Numbered islands scattered across the sea. Join them with straight bridges, horizontal or vertical, one or two between each pair, so that every island has as many bridges as its number. Bridges never cross and in the end all islands are connected. You play by dragging your finger from one island to another.
No guessing. Every board has exactly one solution and you reach it by reasoning. If you get stuck, the hint places the next bridge and tells you why; if you have one too many, it says so.
Three modes. Classic with four levels, from 7 × 7 up to an 11 × 11 Expert with some thirty islands. A Daily challenge with the same board for everyone. And Zen, with no timer.
Genuinely calm. No ads, no purchases and no accounts. Your games, stats and achievements stay on your device.
For everyone. Islands turn green when complete and red when something is off, dark, light and high-contrast themes, left-handed controls, keyboard play and a reduce-motion option. In Spanish, Catalan and English.
Drag your finger from an island to its neighbour to build a bridge; do it again to make it double, and a third time removes it. You can also tap an island and then the other one, or tap the water between them. Each island needs as many bridges as its number, with no crossings and all islands joined at the end.
