This is a one size only version of "shisen slowly" with four each of 27 different tiles.
Its fully playable, with no ads.
If you enjoy this, consider getting the full version, which allows you to set the number of different tiles,how many of each you would like, and a number of other features.
Shisen slowly is a puzzle game similar to mahjong. To match two like tiles, they must be able to be connected by no more than three vertical and/or horizontal lines. Lines can be drawn within or outside of the array of tiles, but may not pass through any other tiles.
You decide the goals of the game:
Do you want to draw the least lines possible, or the most?
... the longest lines, or the shortest?
... the fewest external moves, or the most?
... are doubles desirable or not, and, if so, do you want a long series of them?
... or maybe you just want to end up with a drawing that pleases you!
If you run out of moves (or just feel like it) you can always cheat.
