Something not working, an idea for the game, or a level that has you stuck? We read every message.
If something isn't working, tell us your device, its iOS or Android version and the level, for example "Hard #12".
Questions and answers
How do I play?
Lay one continuous track from the entry to the exit. The numbers show how many track pieces each row and column holds. Tap a square to cross it out, double-tap to place track, and drag to do many squares at once. When every piece is found, drag from piece to piece to connect them. The app's How to play screen has the details.
What happens when I run out of hearts?
You have three hearts, and placing track where there is none costs one. When they are gone, the level starts over. Hints never cost a heart.
How do hints work?
Tap the lightbulb during a level. The hint first shows where to look. Tap Why? to have the reasoning explained, or Show me to have the move made for you. If a cross or a connection on the board is wrong, the hint points that out first and offers to remove it.
Do I need to be online?
No. The app comes with levels to play, and downloads new ones in the background whenever you are online. Before a trip, go to Settings → Offline levels → Download more levels to have up to 200 levels ready per difficulty.
Where is my progress saved?
On your device only. There is no account, so your progress doesn't move to another device, and deleting the app deletes it.
I have solved every level. Now what?
New levels are published from time to time and download by themselves. If the app says to connect to the internet, do that and open the difficulty again.
Can I get a refund?
The store you bought the app from handles the purchase. For the App Store, ask Apple at reportaproblem.apple.com. For Google Play, see Google Play's refund help.
