About game
Numbers fall from above. Matching ones collide and merge. Two into four, four into eight. Place it right and you chain them — multiplier, points. Place it wrong and the board fills up.
No timer. Game ends when there's no space. Difficulty adjustable, records saved.
How to play
Keyboard: ← → move the block, ↑ or Z rotate, ↓ soft drop, Space hard drop, ESC pause.
Mobile: swipe left/right to move, swipe down to speed up, tap to rotate.
Two matching numbers end up next to each other — they merge. The new number lands on a match — merges again. The longer the chain in one move, the higher the multiplier. Board fills to the top — game over. No timer, just space.
