“I Need Practice Programming”: 49 Ideas for Game Clones to Code

So you know a little bit about programming (perhaps you’ve read the free book, “Invent Your Own Computer Games with Python”, a free programming book for beginners whose author shamelessly plugs at every chance) but you want to get better at coding. You can’t seem to find any open source projects that are at your level or easy for new people to contribute to. You’ve gone through a few of the practice problems at Project Euler but you want to create something more substantial, or at least a cool thing you can show your friends. (Not that finding the 31337th prime number isn’t cool.)

Here’s a list of game clone ideas for you to implement. Each has a short description of the game, links to videos of the game, and descriptions of what kind of algorithms you’ll need to know in order to implement them. These games have been selected for their simplicity, so you don’t have to spend several weeks designing art, levels, scripted dialogue, or complicated AI. These are clones designed to be doable in roughly a weekend. A Mario or Zelda clone would be complicated to put together, but a Tetris or Asteroids clone would be doable in a weekend.

Orisinal Games:

The Orisinal website has a great collection of Flash games with very simple mechanics that can be copied. http://www.ferryhalim.com/orisinal/

I especially recommend Winter Bells, A Daily Cup of Tea, Bugs, and Hold the Rope!

The Wikipedia entry for video game clones also lists some ideas.

Games from “Invent Your Own Computer Games with Python” and “Making Games with Python & Pygame” books:

These games are described in these free Python programming books and their source code is available. However, you can make your own variants.

1. Dodger

Description: Several bad guys fall from the top of the screen, and the user must avoid them. The player can be controlled with the arrow keys or more directly with the mouse. The longer the player lasts without being hit, the higher the score.

Variations: Have enemies fall at different rates and be different sizes. Have enemies fall from more than one side of the game. Have power up pickups that grant invulnerability for a while, slow down bad guys, give the player a temporary “reverse bad guys” power, etc.

This game is covered in Chapter 20 of “Invent with Python”

2. Memory Puzzle

Description: A board full of overturned cards. There is a pair for each card. The player flips over two cards. If they match, then they stay overturned. Otherwise they flip back. The player needs to overturn all the cards in the fewest moves to win.

Variations: Provide “hints” in the form of four possible matching cards after the player flips the first one. Or, quickly overturn groups of cards at the beginning of the game.

3. Sliding Puzzle

Description: A 4×4 board of numbered tiles has one missing space and is randomly set up. To win the game, the player must slide tiles over to put the tiles back in order.

Variants: Instead of numbers, you can have a scrambled picture cut up into 4×4 tiles.

This game is covered in Chapter 4 of “Making Games with Python & Pygame”.

4. Simon

Description: Four colored buttons light up in a specific pattern. After displaying the pattern, the player must repeat the pattern by clicking the buttons in proper order. The pattern gets longer each time the player completes the pattern. If the player presses a wrong button, the game ends.

Variant: A nine-button version can add challenge to this game (but more than that would probably just be tedious.)

This game is covered in Chapter 5 of “Making Games with Python & Pygame”.

Download Pyhton Source: simulate.py

5. Nibbles

Description: A worm or snake constantly moves around the board. The player controls the direction the “head” of the worm moves, and the worm must try to eat apples that randomly appear. Eating an apply causes the worm to grow in length. The game ends if the worm crashes into the edge of the board or into itself.

Variants: Add walls to the level, instead of just a blank rectangle. Add power ups that the worm can pick up. Add bad guys that move around the board that the worm must avoid. Have two worms that the player must control simultaenously. Tron (see below) is a two-player variant of this game.

This game is covered in Chapter 6 of “Making Games with Python & Pygame”.

Download Python Source: wormy.py

6. Tetris

Description: Shapes made up of four blocks fall from the top of the board. The player must rotate and place them to create full rows with no gaps. When a full row is made, the blocks in that row disappear and the blocks above it move down. The game ends if the board fills up.

Variant: Several Tetris variants are listed on Wikipedia. http://en.wikipedia.org/wiki/List_of_Tetris_variants

This game is covered in Chapter 7 of “Making Games with Python & Pygame”.

Download Python Source: tetromino.py

7. Katamari Damacy

Description: The original Katamari Damacy game was in a 3d world, but a 2d version is also easy to implement. The player controls a small object in a world of different-sized objects. Touching the smaller objects grows the player, touching the larger objects damages or shrinks the player. The player wins when they reach a certain size.

A flash version of 2D Katamari is available.

This game is covered in Chapter 8 of “Making Games with Python & Pygame”

8. Sokoban

Description: The player is in a level with objects that need to be pushed over goals. The objects can only be pushed, they can’t be pulled. This game does require some effort to design levels for, but Sokoban levels have been designed by others and published on the web.

Variant: Add all sorts of level gimmicks: teleport tiles, conveyor belts, buttons that open doors/bridges, buttons that need an object left on them to keep a door open.

This game is covered in Chapter 9 of “Making Games with Python & Pygame”.

9. Othello

Description: On a grid, a black and white player places tiles of their color on the board. The opponent’s tiles between the newly placed tile and that player’s existing tiles are flipped to become the color of the player’s tiles. The game ends when the board fills up and the player with the most tiles of their color wins.

Variant: Three player Othello with three different colors. Non-square boards.

10. Flood It

Description: A grid of six colors of tiles starts off randomly. The player can do a “flood fill” on the top left tile, changing the color of any adjacent tiles of thesame color. The player wins if they are able to make the entire board a single color within a certain number of moves.

Variants: Power ups gained when a certain tile is changed.

11. Connect Four

Description: Two players of different colors drop their tokens on an upright board. The player to make four tokens in a row, column, or diagonal wins. Creating an AI for this requires a simple minimax algorithm.

Variant: Different board sizes. Walls inside the board that appear when the spaces beneath them are filled.

This game is covered in Chapter 10 of “Making Games with Python & Pygame”.

12. Bejeweled

Description: The board is filled with seven different types of jewels. The player can swap two adjacent jewels to form a three-in-a-row, causing the jewels to disappear and the jewels on top of them to fall down. Creating chain reactions gives bonus points.

Variant: Different power ups for matching a particular jewel. Be able to sometimes swap jewels that are not adjacent to each other. Timed games.

Board Games:

Board games are a good source for game clone ideas. A game like Monopoly has far too many rules to put together in a short time frame, but here’s a list of board games that have simple mechanics. Chess, Go, and Stratego may be too complicated to create an AI opponent, but in that case you can just make it a two-player game. These games don’t really have variants,

13. Mancala

YouTube video showing gameplay. Mancala rules

Description: A stone capture game where the board is made up of 12 pits and a “score pit” that the player tries to move their stones into. A simple minimax algorithm can be used by the AI.

Variants: Wikipedia has a list of “mancala games”.

Source code for Awale, a Mancala variant.

14. Tic-tac-toe

Wikipedia page explaining rules.

Description: Players put down their X or O symbol on a 3×3 board and try to get three in a row.

Variants: Using a 3x3x3 board for 3D Tic-tac-toe. Wikipedia has a list of variations.

15. Quarto

Description: Two players take turns setting one of the 16 pieces which is either: tall/short, light/dark, square/circular, and hollow/solid. The goal is to get four in a row of a common trait.

Variants: You can increase the board size and the number of types of pieces.

16. Abalone

Wikipedia page with game rules. YouTube video explaining the rules.

Description: Players move their marbles around a hexagonal board, trying to be the first to push six of the opponent’s marbles off the edge of the board.

17. Quoridor

YouTube video explaining the Quoridor rules

Description: Two players try to move their token to the other side of the board. On their turn, they can either move their token one space or place a wall on the board. A player cannot completely seal in the other player with a wall. An AI for this game may be too complex, but a two-player version should be simple to implement.

Variants: See Minotaurus, the next game.

18: Minotaurus

YouTube video showing gameplay.

Description: This game is essentially a more complex and multiplayer version of Quoridor, with a “Minotaur” monster added in that can attack players.

Variants: Add different level/wall designs instead of the standard board. Add teleports, or buttons that can activate doors and bridges.

19: Stratego

YouTube video explaining the rules and demonstrating gameplay. Wikipedia page explaining rules.

Description: Two players set up army units on the board and try to determine the strength of their opponent’s units. Disinformation is an important aspect of the game.

20: Blackjack

Variants: There are too many to list here. See the Wikipedia entry for Scrabble Variants.

22: Grid Lock / Traffic Jam

YouTube video showing gameplay.

Description: The player must slide a target car through an exit, but other cars are blocking the way. Cars can only be moved vertically or horizontally depending on their starting orientation. Level designs can be copied from existing games.

23: Yahtzee

Yahtzee rules explained.

Description: Dice rolling game where the players try to achieve specific patterns of rolls.

Variants: Variants are listed on the Wikipedia page.

24: Risk

YouTube video of Dicewars gameplay.

Description: Each territory has a certain number of armies which can be used to attack adjacent territories. The player can attack as often as they want, but conquering too many territories stretches out their troops so that the territories can be reclaimed easily. Additional armies are given based on conquered territories, so not expanding fast enough will also lead to losing. A straight forward AI is relatively easy to produce.

Variants: Dice Wars is a high-speed Flash game that is similar to Risk.

25: Checkers / Draughts

YouTube link of a Checkers game.

Description: A player moves their pieces diagonally on a board and tries to “jump” the opponent’s pieces.

31: Missile Command

YouTube video showing gameplay

Description: Missiles are shot up from the ground to hit falling meteors before they hit cities. The missiles must be timed so that they reach their target at the same time that the meteor is there.

Variants: See Rampart below. Different weapon types (the kind used in Scorched Earth) are also possible.

Python source code

32: Pong

YouTube video showing gameplay

Description: A tennis game where players bounce a ball passed the other.

Variants: Several of the same variations found in Arkanoid can be used in Pong. Obstacles can be placed on the map instead of just an open field.

33: Arkanoid

YouTube video showing gameplay

Description: The player controls a paddle that bounces a ball off of bricks in the level. The bricks break when the ball bounces off of them. The level is cleared when all the bricks are destroyed.

Description: Players control tanks on a 2D hilly terrain and enter the numeric angle and velocity of a cannonball shot. The object is hit the other player’s tanks.

Variants: Angry Birds is a version of this game that adds a physics engine instead of hills. Different weapon types besides the standard cannonball can be added. Several UI improvements can be made over the original game (using the mouse to enter the angle and velocity, displaying the previous turn’s angle and velocity, etc.) Destructible terrain and being able to move the tanks adds a new dimension to the game.

36: Lunar Lander

YouTube video showing gameplay

Description: The player controls a ship that must gently land on a flat surface of the moon. The ship has limited fuel, and using the thrusters affects the momentum of the ship (much like Asteroids).

37: Snood / Bust-a-Move

YouTube video showing gameplay of Snood YouTube video showing gameplay of Bust-a-Move

Description: The top of the board is filled with different colored bubbles. The player must shoot bubbles from the bottom to form a set of three bubbles of the same color in a row to make them disappear. The ceiling lowers over time. The player wins if the board is cleared of bubbles, and loses if the bubbles reach the bottom.

Variants: This is a similar game to Bejeweled, and the power ups used in that game could be used in this one.

38: Fruit Ninja

YouTube video showing gameplay

Description: Objects are thrown up over the screen and the player must drag the mouse over them.

Variants: Bonuses for combos. Some objects cause the player to lose if they are touched.

39: Last Stand

Variants: Different enemy types (slow moving, armored ships or fast moving airplanes) and weapons can be added. Add different strength walls to build.

42: Bloxorz

YouTube video showing gameplay

Description: A puzzle game where the player must roll over a 2×1 brick to an exit point on the map. The brick cannot be moved off the edge of the board, and since it can only be flipped end over end and not slid around, the 2×1 nature restricts the types of moves it can make.

43: Dr. Mario

YouTube video showing gameplay

Description: A Tetris-like game where two-colored pills fall on different colored germs. Forming four in a row of the same color germ/pills causes them to disappear. The player wins when all the germs are cleared from the board, and loses if the pills fill up the board.

Variants: Similar to Puyo Puyo.

44: Kirby’s Avalanche / Puyo Puyo

YouTube video showing Kirby’s Avalanche gameplay Wikipedia entry for Puyo Puyo

Description: Essentially like a two-player Dr. Mario without the germs.

45: Fire ‘N’ Ice

Description: A very original but obscure puzzle game on the NES. The player controls a wizard who can make and unmake ice cubes, which need to fall on all the fire in a level to clear it. The ice can also be used as platforms, and individual blocks of ice can be pushed around. (As a platformer, making a clone of this might be a bit more involved. But the concept is original enough where I think it’d be worth the effort.)

46: Typespeed

YouTube video showing gameplay

Description: A typing game where words slowly move to the right side of the screen. The player must type the word to make them disappear. The player loses after enough words hit the right side of the screen.

47: Diner Dash

Variants: Usually there are ways to streamline tasks by doing them in a certain order (e.g. the player can carry meals for two tables at the same time).

48: Pipe Dream

YouTube video showing gameplay

Description: The player must put down different shaped pipes on the board. The pipes cannot be rotated or moved after placement, but the player does get to see the next several pipes that will be used. A little after the start of the game, water begins to flow through the pipes.

49: Zoop

YouTube video showing gameplay

Description: Colored bubbles begin to appear from four sides of the board. The player can assume the color of the bubbles, and then destroy bubbles of a similar color. The game ends if the bubbles fill up one side of the board.


  1. [...] (el cual sacó recientemente un libro para aprender a programar con Python y PyGame) ha publicado una lista de 49 ideas de juegos para clonar cuando quieres aprender o practicar tus habilidades de [...]

  2. There are many games with “doodle jump” mechanic.

    It’s easy to implement, and very fun to play.

    I think it’s unfairly forgotten.

  3. Great list, only one I disagree with being called “simple” is Rampart, mainly due to the checking required (via flood fill etc) to determine if you have a fully walled off zone.

  4. Nah, recursion and the flood fill algorithm are really easy. I have a tutorial on it here: Recursion Explained with the Flood Fill Algorithm (and Zombies and Cats)

  5. Great List!!
    I was considering about 1/3 of it when learning new platforms.

    Agree with others that rampart not so easy one.

  6. Really nice list! Too bad I didn’t have it back then when I start programming games.

  7. Fire n Ice. I forgot about that game altogether. Nice list.

  8. Don’t list Go here. Is one of the most dificult AI problem. It can took years…

    NOTE FROM AL: An AI for Go is indeed difficult, but a two-player human vs. human game is simple.

  9. Awesome list, and how about this one for #49:


  10. these are much needed! thank you
    im a beginner game programmer(iv been using python for about 2 years now) and i have picked up you books to learn game programming. they are very handy and im learning alot. but im not really sure how to incorporate somethings into making game copys. im working on a pong game right no so far i have the two pong sticks moving together but im not sure how or where to add the rest of the coding.( i know how to draw images, move objects with the mouse and keys but after that im lost.) any tips?

  11. awesome game examples. excellent ways of teaching new beginners how to manage game controls in python.

  12. These are cool ideas, I imagine these could be done using any other language such as C++????

  13. i want a suggestion for a simple easy to make game something like cars dodging obstacles?
    any suggestions?

  14. Thanks that realy helped
