Color Block Fall

Fill the arena with blocks!

Shapes fall from the top of the arena. Your job is simple to describe and properly satisfying to do: fit every one of them below the line, with no gaps left over.

There is no scoring combo to chase and no clock running down. A level is cleared when the last piece lands and nothing pokes above the dashed line. The arena is meant to end completely packed — which means every piece has a place, and finding it is the whole game.

ONE THOUSAND LEVELS The campaign climbs gently. Early boards are small and forgiving, with chunky shapes and a flat floor. Later ones bring pentominoes, wider arenas, uneven terrain to build around, and a quicker fall. The curve was tuned by hand, level by level.

EVERY BOARD IS SOLVABLE Each level is checked by a solver before it ships, and only boards with at least three genuinely different solutions are kept. You will never be handed something impossible — if it feels stuck, there is another order that works.

A PUZZLE EVERY DAY One fresh board daily, the same one for everyone, with a calendar of what you have solved and a streak to keep going.

DEAL YOUR OWN Five difficulties, from a quiet warm-up on small boards to eight columns of pentominoes over deep terrain. Enter a seed to replay a board you liked, or pass it to someone else.
