Jamble: Block Puzzle

Slide the bricks out — and mind the mixed doors. Every brick is red, yellow or blue. Every door on the edge of the board is one of those three, or a mix of two: orange takes a red AND a yellow, green takes a yellow and a blue, purple takes a red and a blue. Send the first brick through and the door holds that colour, waiting for its partner. So the question is never only which order to clear in. It is whether the partner can still reach the door once the first brick has changed the board. Get it wrong and undo is free and unlimited. 240 hand-checked levels, every one of them solvable.
