Color Block Jam is a sliding-block logic puzzle: every colored block must leave the board through the exit of its own color, and the order you choose decides everything.
Each block shows an arrow – the only direction it can move. Tap it (or swipe along the arrow) and it slides toward the colored exit on the border. It leaves only if the whole lane is clear.
If another block or a wall is in the way, the block just nudges or slides up to the obstacle. Free the lane first by sending the blockers out, then come back for it.
Every tap costs a move, even on a blocked block. Finish with moves to spare to earn up to three stars, and send same-colored blocks out in a row for chain bonuses.
Careless partial slides can lock blocks into a loop where none can ever reach its exit. Use Undo to step back, or a Hint to reveal a safe move.
Play Color Block Jam free online: slide colored blocks out through their matching exits, clear blockers in the right order and solve 50 tricky puzzle levels.
