Step01—Meet the board
This is Hashi.
Numbered circles are islands. Each number tells you exactly how many bridge ends that island needs. Bridges run horizontally or vertically between islands that share a row or column.
Rules in play
- Each island's bridge count must equal its value
- Bridges cannot cross each other
- All islands must form one connected group
Island
The number is the total bridge ends this island requires.
Single bridge
One connection between two neighboring islands.
Double bridge
Two connections — the maximum allowed between any pair of islands.
