How to play Hashi Bridges
- Select an island, then a neighbouring island in the same row or column. Each pair cycles through no bridge, one bridge and two bridges.
- An island’s number is the total bridges touching it. Green islands currently match their clue; pink islands have too many bridges. You may adjust an incorrect pair again.
- Match all nine island clues and connect every island into one network to win. Bridges cannot skip an intervening island. This compact layout uses a 3×3 island lattice, so allowed links do not cross.

Matching numbers is only part of the goal
Each bridge consumes capacity at both endpoints. Before adding a second bridge, compare what both islands still need. A local group can satisfy its numbers while remaining disconnected from the rest of the puzzle; that is not a finished network. Keep at least one possible connection between developing groups as you approach the final clues.
A corner needs four bridges
A corner island has only two neighbouring islands. If its clue is 4, both links must be double bridges because each pair allows at most two. Add those bridges, then subtract their contributions from the neighbours’ remaining needs. A forced corner can determine several later choices.
A focused practice session
- Look for corner clues that force one or two double links.
- After adding a bridge, recalculate both endpoint totals.
- When every island is green, check whether the whole network is connected.
What to keep in mind
Some generated clues can admit several valid networks. Any clue-matching connected network is accepted. The 3×3 lattice is a compact introduction rather than a full irregular-island generator.
