Cube Collapse

Cube Collapse is a classic collapse puzzle built from chunky, bevelled cubes. The board is a grid of bright colours: tap a group of two or more connected cubes of the same colour and it crumbles to pieces. Everything above falls into the gap, and any column that empties out slides across to close the space. Points rise with the square of the group, so a pair is worth 10 while a group of ten is worth 810, and the real puzzle is setting up those big groups before you take them. Clear the whole board for a 2,000 point bonus; leave just a few cubes and you still get something for it.

Big groups leave a special cube behind. Pop six or more at once to build a Rocket that clears its row or column, nine or more for a Bomb that blasts everything around it, and thirteen or more for a Rainbow that removes every cube of the most common colour. Specials set each other off, so a rocket that runs into a bomb turns into a chain. Levels has fifty boards, each with a target score and up to three stars, starting with three colours and working up to six. Every level ships with a full solution found by our own solver, so every target is known to be reachable.

Endless is the quick, frantic one: new rows push up from the bottom on a timer that speeds up as you go, and the run ends when the stack hits the top. Your high score is saved in your browser. Daily gives everyone the same board for the date, a nice brain warm-up with your best score for the day kept. Levels and Daily have no clock, so you can relax and plan every move; a move counter keeps track, and when no groups are left the board ends gracefully and adds up your bonus. Click or tap a group to pop it, or use the arrow keys and Space; P pauses and M mutes.
