December Daily Block Puzzles

Every day in December has its own permanent daily block puzzle — 31 in total. Each 9×9 board is generated deterministically from the date, so the starting layout, the difficulty, and your first three pieces are identical for everyone who plays that day. Pick a date below to open its fixed challenge, or start the main block puzzle for an endless run.

Weekday boards play Easy, weekends step up to Medium, and Sundays bring the Hard set with chunkier shapes. Clear full rows, columns, and 3×3 boxes, and chase combos for the high score — then compare with friends on the same board.
