Tidalis is a block-based puzzle game with casual appeal, hardcore depth, and an addictive new “streams” mechanic. The basic rules of the game are this: blocks fall down into the board and have a color and an arrow direction. If a stack of blocks exceeds the height of the board, you lose. In order to clear blocks, you must right-click and drag paths through the arrows to set up chain reactions of like-colored blocks.
