Bridges
Connect all islands in one network. Use one or two bridges per connection, with no crossings, to meet each number.

Time—:——
Drag between islands or tap the space between them to toggle a bridge.
Network connected
Connect islands horizontally or vertically. Two islands can have one or two bridges between them; you can also tap the space between them to cycle the connection.
Each island number tells you how many bridges must leave it. Bridges cannot cross or pass through other islands.
The solution forms one connected network. Repeat a connection to cycle between one, two, or no bridges.
