Tangled Climber Escape

A group of climbers has ended up hopelessly tangled on a mountainside and only you can sort out the mess. Tangled Climber Escape asks you to move climbers between anchor points until none of the ropes cross, and it gets properly tricky once the levels start piling on more climbers and less room to work with. There are power-ups for when you get stuck, including one that cuts a rope outright and one that buys you time. A genuinely good brain workout, free in your browser.
