Fourtris Saving Pigs

A pig family is trapped on a platform rising toward the spikes above in Fourtris Saving Pigs. Pull them down before the platform reaches the top. Logic drives the rescue. The puzzle uses Tetris-style pieces with different rules.

How to play?

Each falling piece is a 2x2 square with four colored cubes. Swap the cubes inside that square to make horizontal or vertical matches of three or more of the same color. Matched cubes vanish from the board. Each match lowers the pigs' platform a little. When the pigs reach the bottom and get off the platform, the next level unlocks. The board does not reset between levels. There are no power-ups or hints. The run ends if the pigs touch the spikes or if the stacked cubes reach the top of the screen.
