Bridges: Logic Puzzle

🌉 The bridges logic puzzle, with every size and every difficulty open from the first minute.

Islands carry a number. Join them with bridges, straight across or straight down, until every island has exactly the bridges it asks for.

🔑 THREE RULES AND THAT IS ALL
Zero, one or two bridges between two islands, never diagonal. Bridges never cross each other. And when you finish, every island has to hang together in one single piece — that last rule is where the real deductions live, and the one most apps forget.

💸 NO SUBSCRIPTION. NOT ONE EURO A WEEK.
No weekly plan, no "pro" sizes, no coins, no lives. The boards are generated by the app on your own phone, so renting them out would be charging you for arithmetic. Ads pay for it and nothing is locked behind them.

🪜 FIVE SIZES, FROM 7×7 TO 25×25, AND NOTHING LOCKED
Every puzzle the game offers is open the first time you launch it: nothing to grind, nothing to buy, no gate and no "pro" tier. And because the boards are generated, they do not run out.

🧠 A HINT THAT NAMES THE RULE
Ask for a hint and it does not drop a bridge on the board. It tells you in words which deduction you missed, and lights up the islands it is talking about: "This island has a single neighbour left, so every bridge it still needs goes there." You learn the technique instead of being handed the answer.

📅 DAILY CHALLENGE
A new board every day, the same one for everybody. Keep the streak.

👆 MADE FOR THE THUMB
Tap one island and then its neighbour: once for a bridge, again for the double, once more to take it away. Pinch to zoom on the big boards. Undo when your finger slips, and check the board when you suspect a mistake.

🎨 BOARD COLOURS
Four palettes, paid for with the stars you earn playing — never with money.
