Soda Block Jam

Soda Block Jam takes the familiar sliding-crate puzzle and gives it a collection rule that changes everything. You swipe a crate and it moves in a continuous motion across the board, picking up bottles of its own colour as it travels — but bottles of other colours and other crates both block the way, so the route a crate can take is constrained by everything else on the board. Once a crate is full it exits through its designated exit, freeing space for the rest. That makes the puzzle a question of order and of route simultaneously: which crate moves, in which direction, and what it clears for the next one.
