Hashi is a logic puzzle which consists of an array of "islands" with numbers on them. The solution requires that "bridges" be drawn between the islands, subject to the following restraints:
- Bridges can only be drawn horizontally or vertically
- The total number of bridges connected to each island must equal the number shown on that island
- No more than two bridges can be drawn on each side of the island (therefore no island will ever have a number higher than 8)
- All islands must be connected into one single mass once the puzzle is complete
