Help & support

Tap a connection between two islands to cycle through a single bridge, a double bridge and no bridge. A single counts as 1; a double counts as 2. Each island needs exactly the number of bridges printed on it. Bridges cannot cross, and all islands must form one connected network.

Rescue levels also need a route from the turtle to the lighthouse made entirely of double bridges. Single-bridge entrances to the lighthouse cannot complete that route, even if every number is correct. Connections outside the rescue route may still use single bridges.

Open Guided practice on Home to revisit bridge building, connectivity and double-bridge rescue. Reset asks for confirmation before clearing the current board. It keeps other completed levels and does not restore a used free hint.

If you started or continued from Home, Back returns to Home. If you entered through the level list, it returns to that list. Your current progress is saved when you go back.

Each hint has three stages: Observe, Think it through, and Next step. Consider the clue, then reveal the reasoning and the specific connection when you need them. Revealing the same hint’s later stages does not use another hint or play another ad. The first hint in each level is free and works offline. Hints never change the board for you.

For free players, each additional hint in the same level requires completing an optional rewarded ad. Cancelling, closing early or receiving no reward grants no hint and does not increase the hint-use count. Remove Ads owners can use unlimited hints directly.

All 120 levels and normal progression work offline. After a free player’s first hint in a level, further hints wait until a rewarded ad is available. You can still solve the puzzle and move to the next level. Remove Ads owners can also use hints offline.

No. Hint counts are saved per level on this device and survive resets and app restarts. Rule explanations are free; using a hint to find a connection that needs correcting follows the normal hint-use rules.

Yes. It uses the puzzle rules to identify a connection to reconsider, names its two islands, explains the number, crossing, connectivity or rescue constraint, then offers a specific next step. Your existing bridges and marks stay unchanged.

The one-time purchase removes ads and includes direct access to all hints without rewarded ads. All 120 levels are already free. The price shown by the App Store inside the app is the price that applies.

Use the Apple Account that made the purchase, connect to the internet and choose Restore purchases in the Shop (the bag beside the Home gear, or Shop in the in-game menu). Allow the App Store verification to finish. If the purchase still does not restore, contact support with the message you see.

A purchase awaiting approval or verification may not be active yet. Check its App Store status, then try Restore purchases. If something is wrong, send your device, app version and the displayed message. Do not send your Apple Account password or payment details.

The first four distinct level completions are protected. An interstitial can first appear after your fifth distinct completion, once the animation finishes and you choose Next Level or Level Select. After a successful ad, four more distinct completions and at least 120 seconds are required. A new installation also has a 120-second grace period. Ads are skipped when unavailable, offline, privacy consent does not permit them, or Remove Ads is active.

There is no sign-in or developer-operated cloud sync. Progress is saved locally. Whether a system backup restores app data depends on your device and backup settings; restoring a purchase does not restore level progress. Do not delete the app to troubleshoot if you want to keep your progress.

Settings includes English, Traditional Chinese, Japanese and Korean, plus music, sound, haptics and display preferences. Open the gear at the top right of Home, or access Settings through the top-right menu during a game.
