About This Game
Bridges brings the beloved Japanese logic puzzle Hashiwokakero to your browser in a clean, elegant format. Islands marked with numbers are scattered across the board, and your task is to connect them with horizontal or vertical bridges so that each island's number matches the total bridges attached to it. Bridges cannot cross each other, and all islands must form one connected network when the puzzle is complete. Every puzzle has a unique solution that rewards careful deduction over guessing. With difficulty levels from gentle introductions to fiendishly complex grids, Bridges offers a deeply satisfying exercise in logical reasoning. Play this free browser puzzle anytime — no downloads, pure deductive thinking.
How to Play bridges
The puzzle presents a grid with numbered circles called islands. Each number indicates exactly how many bridges must connect to that island. Click or drag between two islands in the same row or column to build a bridge. You can place up to two bridges between any pair of adjacent islands. Bridges run in straight horizontal or vertical lines and cannot cross other bridges. All islands must be connected into a single network when the puzzle is complete — no isolated groups allowed. Start with islands showing the maximum possible connections. An island numbered 8 in a corner position must have two bridges to each of its neighbors, so fill those in immediately. Islands with only one possible neighbor must connect to that neighbor with all their required bridges. After placing obvious bridges, look for islands where subtracting already-placed bridges leaves only one valid configuration for the remaining connections. Use elimination logic — if placing a bridge in a certain direction would make it impossible for a neighboring island to reach its number, that bridge cannot go there. Work outward from the most constrained islands to the least constrained ones. Double-check connectivity by mentally tracing a path through all islands. When only a few bridges remain, the correct placement usually becomes apparent through process of elimination.

Tips & Tricks for bridges
- Start with islands at maximum capacity — an 8 in a four-neighbor position fills all connections automatically
- Islands with only one neighbor must send all their bridges in that single direction
- Use subtraction — count existing bridges on an island and deduce how many more it needs
- If a bridge would isolate a group of islands from the rest, that bridge placement is wrong
- Work from corners and edges inward since those islands have fewer possible connections
FAQ
