Read full description

You're the escort: ferry prisoners across the river. But if the guards are outnumbered, they escape! Load officers and prisoners into the boat and get everyone to the far bank without losing a single one. [One simple rule] On a bank or in the boat, prisoners escape if they outnumber the guards. Leave prisoners with no guard, and they escape too. [Plan your moves on a river island] Leave people on an island mid-river. The boat can't go straight across; it stops at the island on the way. But the island needs guards too. Who stays where? [New helpers, tougher prisoners] - Boss: needs two guards alone - Police dog: guards, but can't row - Chief: guards two prisoners alone - Cuffed pair: chained together, takes two seats [120 levels, 3 stars for the shortest route] Every level is solvable. Cross in the fewest trips to earn 3 stars. Stuck? Watch a short video to see your next move (no video with Remove Ads). Undo before anyone escapes; restart any time. The puzzles play offline (hint videos need a connection). Contains ads. The in-app purchase Remove Ads turns off full-screen ads and lets you use hints without videos.
