This is the 2013 iOS version of the Qwirkle boardgame.
The game features 108 blocks with six different shapes in six different colors. Players begin the game with 6 blocks. The start player plays blocks of a single matching attribute (color or shape but not both). Thereafter, a player adds blocks adjacent to at least one previously played block. The blocks must all be played in a line and match, without duplicates, either the color or shape of the previous block.
Players score one point for each block played plus all blocks adjacent. It is possible for a block to score in more than one direction. If a player completes a line containing all 6 shapes or colors, an additional 6 points are scored. The player then refills his hand to 6 blocks.
The game ends when all tiles have been distributed, and one player plays all of his remaining blocks, earning a 6 point bonus. The player with the high score wins.
This implementation features 4 levels of AI opponents, and the ability to customize the colors of the blocks.
