Tips and strategy

• Read every island number first, then count how many neighbors each island can reach. The number divided across its available links tells you where to begin.
• Remember that each line cycles from zero to one to two and then wraps back to zero, so you can always tap onward instead of undoing.
• Use the green outline as live feedback. When an island glows green its total is right, so check that neighbors still balance before moving on.
• Every bridge counts toward two islands at once. Placing one connection changes both ends, so consider both numbers before you tap.
• Press Check Answer only after the outlines look settled, and use the thickness of each line to scan your bridge counts at a glance.

What it exercises

Bridges practices constraint satisfaction, which is the skill of making one choice fit several rules at once. It encourages careful counting, step-by-step deduction and verifying that a local decision still holds when you look at the whole network of islands.

Frequently asked questions

How do you add a bridge in Bridges?

Tap a line between two islands. One tap gives a single bridge, a second tap gives a double bridge, and a third tap removes it again.

How do I know an island is correct in Bridges?

Its outline turns green when the bridges touching it add up to the number inside. Match every island, then press Check Answer to finish.

Can bridges cross each other in Bridges?

In this puzzle the bridges only run along the four sides between neighboring islands, so they never cross. The challenge is getting the counts right on every island.
