Getting your game ready…
Join the islands with horizontal or vertical bridges. An island’s printed number is the total of bridges touching it. You may put one or two parallel bridges between a pair of facing islands. Select two aligned islands to cycle their connection through none, one and two.
A bridge cannot cross another bridge, travel diagonally or pass through an intervening island. Count both lines of a double bridge. A correct number at one island does not prove that every bridge beside it belongs in the final network.
Finish when every island has its required total and all islands belong to one connected network. Separate finished groups do not count as a solution. Undo takes back a connection change; Restart restores the selected puzzle. There is no time limit.
Start with an island that needs nearly every bridge it could receive. An island with two visible neighbours has room for at most four bridges. Its number may force a double connection or rule out leaving one side empty.
Before finishing a pair or group, check how it can still reach the rest of the board. Giving every island in that group its exact total can trap a disconnected network. Keep at least one required connection available until the wider route is settled.
This version presents bridge connections as short wooden spans between stone islands. You choose the links rather than rotate existing tiles. Six fixed puzzles combine local number counts with one global question: can every island reach every other through the bridges? Completion badges and your puzzle selection are remembered; unfinished changes are not.
