Hashi — Bridges
Hashiwokakero: draw horizontal/vertical bridges between islands so each island's number equals the bridges touching it, no bridges cross, and every island joins one connected network. Endless generated levels — each guaranteed to have exactly ONE solution — plus a custom mode for grid size and island count.
Hashi — Bridges is a clean, logical puzzle also known as Hashiwokakero. Numbered islands dot the grid, and you connect them with bridges until every island is satisfied and the whole map links into one network. It's a pure deduction game with no luck involved, ideal for anyone who enjoys a tidy logical challenge.
How to play
Draw horizontal or vertical bridges between islands so that each island's number equals the total count of bridges touching it. Bridges can't cross one another, at most two can run between the same pair of islands, and when you're done every island must belong to a single connected network. Every generated level has exactly one solution.
Tips
- Start with islands whose number forces their bridges, like a corner island needing many.
- A high-value island against an edge has limited directions, so its bridges are often certain.
- Keep the "one connected network" rule in mind — avoid sealing off an isolated cluster.
- Use single bridges as placeholders where a second one isn't yet confirmed.

Objective
Connect islands (numbered circles) with bridges. Each island's number = total bridges touching it. Bridges run only horizontally/vertically between aligned islands, at most 2 per pair, may never cross, and all islands must form one connected network.
Controls
- Tap an island, then tap an aligned island: each tap cycles 0 → 1 → 2 → 0 bridges
- Or drag straight from one island to another
- ↶ Undo, ↷ Redo, ↺ Restart level
- ⚙ Custom mode: pick grid size (6–13) and island count
- Pinch-zoom is allowed on large grids
Tips
- An 8-island needs double bridges in all 4 directions; a 6 on the grid edge needs doubles in all 3
- Corner islands have only 2 directions: a corner 3 has at least 1 bridge each way, a corner 4 has two doubles
- Two 1-islands never connect to each other — they would be isolated
- Likewise two 2-islands never take a double bridge between them
- Satisfied islands turn green, overloaded ones red, crossing bridges flash red — use this as your compass
- Always think connectivity: avoid closed clusters that satisfy numbers but split the network
