TETRACHROMA adds a new dimension to the block stacking action of classic tetromino stacking games: the colors of the blocks matter! Pieces appear in two or more colors, and to clear a line, every block in the line must match. Transform the board with a new color changing mechanic inspired by the classic board game Reversi. Placing a piece adjacent to a line changes the color of the line to match. Plan ahead to maximize your score and clear 15+ lines with a single piece.
