Islands and bridges puzzle
Bridges: free islands logic puzzle online
Connect numbered islands with straight bridges. Every island needs the right count, bridges cannot cross, and the finished network must hold together as one group.
What you solve
Bridges gives you numbered islands with clear horizontal and vertical lanes. Place single or double bridges between visible island pairs until every number is satisfied.
Casual, checked boards
LoopAndGrid grows a solved bridge network first, then turns that network into island numbers and validates the result. The boards load fast, but they still feel fair and readable.
