Bridges
Islands, bridges, and nothing crossing.
Hashiwokakero — bridges, or simply hashi — is a map of islands, each numbered with the bridges it needs: straight lines, at most two between any pair, never crossing, until every island has its number and all of them hang together. Here a tap between two islands builds a bridge, a second tap doubles it and a third takes it away — or drag one out from an island. An island’s number turns grey once its bridges add up and red when there are too many; both are counted from your own board, and there are no hints beyond that.
A new board every day — 7 × 7, 10 × 10, and 15 × 15 — the same for everybody, each with a single solution that reasoning alone reaches. No timer and no account needed: a board left half-done waits for you until the day turns, at midnight UTC.

How to play
Join the islands with bridges until each island has exactly as many as its number says.
Bridges run straight — across or down — never cross, and at most two can join the same pair of islands.
In the end every island must hang together in one connected group.
Tap between two islands to bridge them, or drag out from an island. Repeat for a double, once more to clear.
