How to play
The goal
Each level is a small grid of wires, one battery and some lamps. Rotate the wires so that the battery is connected to every lamp, with no open ends (a wire leading nowhere) and no loops. The level is solved the moment the circuit is correct.
Controls
Tap a cell to select it, then turn the Digital Crown to rotate it by a quarter turn in either direction. A tap on the selected cell rotates it too. Undo takes back the last turn.
Move limit
Every level has a move limit shown at the top of the screen. Each quarter turn counts as one move. If you run out, tap Restart to try the level again; Undo also gives moves back.
Fuses
Some wires carry a fuse: a small capsule with dots in the corner of the cell. Each turn uses up one dot. When the dots are gone the fuse blows and the level fails, so plan those turns first. Undo repairs a blown fuse.
Gears
Cells marked with a toothed ring are linked. Turning one of them turns its partner as well: neighbouring gears turn in opposite directions, gears one cell apart turn the same way. A linked turn counts as one move.
Other elements
Riveted wires are bolted down and cannot rotate. Crossings carry two independent wires. Larger levels scroll sideways: swipe to see the rest of the board.
Purchases
What is free and what is paid?
The first 15 levels are free. Everything after that is unlocked by Full Game, a single one-time purchase billed through your Apple Account. No subscription, no consumables.
How do I restore a purchase?
Open the app, go to Settings → Restore Purchases, and confirm with the Apple Account that made the purchase. Full Game supports Family Sharing, so family members in your group can restore it on their own watch.
Can I get a refund?
Purchases are made through the App Store, so refunds are handled by Apple at reportaproblem.apple.com.
Progress
Where is my progress stored?
On your watch, and in your own iCloud account so it follows you to a new Apple Watch signed in with the same Apple Account. Nothing is sent to the developer. Deleting the app removes the local copy; the iCloud copy is restored when you reinstall.
The Digital Crown does nothing
Tap a cell first so the board has focus. If the watch display went to sleep, raise your wrist and tap the cell again. Crown sensitivity can be changed in the app's Settings.
