Every island takes its number.

Each island shows how many bridges it needs. Lay exactly that many, counted in every direction.

All rules
Rule 01Every island takes its number.

Each island shows how many bridges it needs. Lay exactly that many, counted in every direction.

Rule 02One or two bridges between two islands.

Bridges run straight across or down, from island to island. Tap or drag again for a second; a third time takes them up.

Rule 03Bridges never cross.

A bridge cannot pass over another. The board refuses one and shows where it would have gone.

Rule 04All the islands join up.

Every island must reach every other over the bridges; a finished group cut off from the rest is marked. Every day has one answer. Stuck? A hint lays or corrects one bridge.

Tap the water between two islands, or drag from one toward the other: one bridge, two, then none · keyboard: arrows move between islands, Shift+arrow lays a bridge
