Hashi (Bridges Puzzle) is a logic game played on a rectangular grid. Certain cells contain numbered circles – known as “islands.” Your goal is to connect all islands with bridges to form a single, continuous network. Each number indicates how many bridges must extend from that island. Bridges may only run horizontally or vertically, must not cross, and a maximum of two bridges may connect any pair of islands. Through logical reasoning, combination, and elimination, you gradually work your way toward the complete solution.

5 Tips for Solving Hashi Successfully

1. Start with islands that offer clear guidance

Islands with low numbers (e.g., 1 or 2) or high numbers (e.g., 7 or 8) often have limited possible configurations – making them ideal starting points.

2. Pay attention to island placement

Islands located on the edge or in the corner of the grid have fewer possible bridge directions. Use this restriction to your advantage.

3. Keep the overall network in mind

All islands must be part of a single, connected structure in the end. Avoid creating isolated groups that cannot later be linked.

4. Use the process of elimination

If a bridge in a specific direction is clearly not possible, rule it out consciously. This will help you focus on the remaining viable options.

5. Place double bridges strategically

In some cases, it's clear that two bridges are required between two islands. Establishing these early can help narrow down possibilities for nearby islands and lead to further progress.
