Hashi Classic - Bridges Puzzle

A grid of numbered islands. Draw bridges between them until every single island is connected into one big network. A logic puzzle where the answer is always there — waiting to be found. Every island has a number. That number is exactly how many bridges must connect to it. Bridges go left, right, up, or down — straight lines only. Bridges can't cross each other. Two bridges max between any pair. When every island has the right count and they're all linked together — the puzzle is solved. Simple rules. But the deeper it goes, the more thinking it demands. One wrong bridge and the whole network falls apart. One right move and suddenly the entire puzzle opens up. A number puzzle that looks easy and plays deep — the kind of brain teaser that stays in the mind long after the phone is put down. WHAT IS HASHI? Hashi (short for Hashiwokakero) is a classic Japanese logic puzzle — like Sudoku, but instead of filling in numbers, it's about building bridges. A favorite brain teaser in puzzle books and magazines for decades. Hashi Classic brings it to mobile with 500+ levels, from beginner-friendly grids to puzzles that demand minutes of focused thinking. A NUMBER PUZZLE BUILT ON PURE LOGIC Every puzzle has a logical path to the answer. No luck, no random chance. Each island's number is a clue — connect islands with bridges, match every number, and the solution reveals itself. Start with the islands that only have one possible move. Work outward. Notice which bridges are forced. Eliminate what doesn't fit. Sudoku fans already know how satisfying that feels — the moment where guessing stops and knowing begins. 500+ LEVELS Six difficulty tiers: Tutorial, Easy, Medium, Hard, Heavy, and Insane. Small grids where the answer is obvious in seconds. Then Insane — a 15×22 grid with islands numbered up to 8, 30+ bridges to figure out. Every level designed by hand — each logic puzzle has a shape, a flow, a moment where it all clicks. A NEW DAILY PUZZLE Every 24 hours a fresh Daily Challenge appears. Solve it to keep the streak going. A small daily brain teaser — like doing the crossword or the morning Wordle. SMART BOOSTERS Two boosters for when it gets tough.
