Logjam: River Logic

Morning on a forest river, and the raft is stuck in a logjam. Slide the logs out of its way and guide it out through the gap in the bank – in as few moves as you can.

Logjam is a calm, clever sliding-block puzzle. Nothing is hidden and nothing is random: every river has a known shortest way out, its par, and the fun is finding it.

HOW YOU PLAY
• Drag a log along its length: logs lying along the river slide left and right, logs lying across it slide up and down.
• A log slides as far as the water is free, never through another log or a rock.
• Get the raft out through the gap in the right bank.
• Reach the gap in par for three stars; a few moves more still earns two.
• Undo any move, or start the river over.

HINTS THAT HELP
Stuck? The hint first outlines the log to move, then shows where it goes and how many moves are left from there, and can make the move for you.
