How to play Bridges

Islands with numbers. Join them with straight bridges, across or down, so each island has exactly its number of bridges.

Goal

Place every bridge: none crossing, at most two between a pair, and every island connected to all the others. Each puzzle has one answer.

Tap the water between two islands to add a bridge; tap again for a double; once more to remove them.
Or tap one island, then the other.
An island turns green when it has its number and red when it has too many.
The sea grows from 7×7 with about 8 islands on Easy to 10×10 with about 22 on Expert.

An island whose number is twice its number of neighbours needs double bridges to all of them.
Two 1s can't join each other - they'd be cut off from the rest.
On Easy and Medium, a hint sets one bridge of the answer.

Every correct answer is worth 100 points, scaled by difficulty (Easy ×0.8, Medium ×1, Hard ×1.3, Expert ×1.6).
Answering within 3 seconds adds a 25-point speed bonus.
Each answer in a row adds a 15-point streak bonus, up to 10 in a row.
Using a hint halves the points for that answer and skips the bonuses. Hints are only available on Easy and Medium.
Your score, streak and achievements are saved to your account when the game ends.
