NAGI: Bridges Logic Puzzle

Got five minutes? Connect the islands with bridges and give your mind a calm workout.

NAGI is a number logic puzzle that is easy to learn and deeply satisfying to solve. Each island shows how many bridges it needs: draw them horizontally or vertically and join every island into one network. No timer, no rush: perfect for a coffee break, the commute or winding down before sleep. If you enjoy sudoku, nonograms or kakuro, you will feel at home. The puzzle is also known as Hashi, Hashiwokakero or Bridges.

600 generated puzzles, each individually verified to have exactly one solution. Six chapters progress from small boards to demanding networks. All levels are available from the start.

Play offline, with automatic local saves, undo and redo, board zoom, day and night themes, optional sounds and haptics. A playable tutorial teaches the rules. Earn a completion mark without hints, or reveal a bridge when you want help.

The daily challenge selects a puzzle from the included collection and tracks your streak. No account is required. Progress stays on your device, with Android backup where enabled.

A few rules. Endless possibilities.
• Each number is the total number of bridges that must touch that island.
• Drag between two islands, or tap one and then the other. Repeat to add a second bridge; repeat again to remove both.
• Bridges run horizontally or vertically. They cannot cross or pass through an island.
• Connect every island into one network. Matching the numbers alone is not enough.
