tap an island to start a bridge

📖 How to play

• Tap an island, then tap another island in the same row or column to build a bridge.
• Tap the same pair again for a double bridge; a third tap removes it (cycle 0-1-2).
• Each island needs exactly the number of bridge ends shown on it: green means done, red means too many.
• Bridges cannot cross each other, and in the end every island must be part of one connected network.
• The win is detected automatically. Fewer taps = more points: each level is worth 150 pts minus 3 per extra tap (min 50).
