Four games, one grid

Seven tetrominoes, ten columns, gravity that speeds up. Clear lines to score, four at once to score properly.

Three shapes at a time on an eight by eight board. Fill a row or a column to clear it. It ends when nothing fits.

Eat, grow, and never meet yourself. Twenty-one squared, speeding up as you lengthen, with solid or wrapping walls.

A vertical shooter with a parallax starfield, weaving formations, and three shields. Auto-fire on, so all you manage is position.

A side-scrolling platformer with coyote time, a jump buffer, and variable jump height. Collect coins, stomp what moves, reach the flag.

Five rows of brick, two hits on the top two. The bounce angle comes off where the ball meets the paddle, which is the whole skill of it.

Four by four, slide to merge. Ten doublings from four to 2048 — and the board fills up long before you are ready.

Tap to flap, fall the rest of the time. Every tap gives the same lift however fast you were dropping, which is why it is fair and still brutal.

A generated grid with a unique solution, four difficulties, conflict highlighting, and a pencil-mark mode.

A block of aliens stepping sideways and down, four bunkers, one ship. They speed up as their numbers thin.

Four tokens, one 52-square loop, three opponents who play to win. A six opens the yard, landing on a token sends it back, and only an exact count reaches the centre.
