Hextris is a fast hexagonal twist on falling-block puzzles. Coloured blocks fall toward a spinning hexagon; rotate it to stack three or more matching colours and clear them before the pile reaches the edge.
Blocks slide in from the edges toward the centre hexagon. Rotate the hexagon so each block lands on a matching colour. Three or more touching blocks of the same colour disappear. The pace rises steadily - keep the stacks low.
