Evolomino (Evolmino)

Game Rules: Evolomino

Build shapes along each arrow. The next shape keeps the previous one in the same orientation and adds exactly one square.

Tap white cells to draw squares. Grey cells are blocked and dark outlined squares are fixed. Squares sharing an edge form a block. Each block must have exactly one square on an arrow. Each arrow visits at least two blocks. Along the arrow, each next block keeps the previous shape without turning or flipping and adds exactly one square. Hold to mark a cell empty, and repeat an input to clear its mark.
