Fish Escape is a free, browser-based logic puzzle. Every level is a tank crowded with fish, and your job is simple to describe and surprisingly tricky to do: free every fish by tapping it so it swims out through the edge of the tank. Each fish only swims straight ahead, and it can only leave if the whole lane in front of it is clear — no rocks, no seaweed, and no other fish in the way.
The twist is that when a fish escapes, it leaves a trail of seaweed in the lane it swam through, and that lane stays blocked for the rest of the round. So the order in which you free the fish is everything. Pick the wrong order and you can box yourself into a deadlock where nobody can move. It is the kind of game you can dip into for one quick round, or lose an hour to while you hunt for the one clean solution.
Fish Escape started as a small experiment in "sliding-block" style puzzles — the family of games where the challenge is untangling a crowded space one careful move at a time. We wanted something calming to look at, gentle to start, and genuinely hard by the later levels, without timers, energy meters, or anything that nags you to come back. Just you, a tank of fish, and a puzzle to unlock.
The result is 100 hand-tuned and procedurally-generated levels that climb from friendly to fiendish. Early tanks teach you the rules. Middle levels introduce longer fish that stretch across many cells and can face left or right. The final stretch mixes tight spaces, long fish and blocked cells into puzzles with only a handful of winning orders.
Fish Escape is built and maintained by Sarthak Manchanda, an independent developer based in India. It is a solo, self-funded project — every level, illustration and line of code is made in-house. Advertising through Google AdSense, together with a small optional ad-free upgrade, is what keeps the game free to play for everyone.
Because it is made by one person, feedback genuinely shapes the game. If a level felt unfair, a control felt off, or you have an idea, we would love to hear it — write to us at sarthak@smartdietplanner.com.
