About expert hashi

Fifteen-by-fifteen grids with 25 to 40 islands. Multi-step deduction chains are required: a bridge forced by connectivity in one corner of the grid triggers an elimination in the opposite corner. Each deduction depends on the previous one.

At this level, tracking which bridges are placed and which remain possible requires focus. The grids are dense enough that bridge crossings become a real constraint. Placing one bridge often blocks a path that other bridges need, so think ahead.
