Frequently asked questions
How do I play?
Tap two numbers that are the same or add up to 10. They can be next to each other across, down or diagonally, or have only crossed-out cells between them. The end of a row also connects to the start of the next. Clear the board to finish the stage. How to play in the app walks through it with a practice board.
I'm stuck. What now?
Tap Add numbers to copy every remaining number to the bottom of the board. You get 5 per stage. You also get 3 free hints each stage; a hint shows one pair, and is not used when there are no pairs.
What is the Daily Puzzle?
One board per day, the same for everyone. Solve it on its day to build your streak. Missed days from the past week can still be played; they just don't extend the streak.
Are there ads?
No, and there never will be. The whole game is free. Optional hint packs and tips help support development.
I bought hints. Will I lose them if I reinstall?
Your purchased-hint balance is kept in your iCloud account, so it comes back when you reinstall or use the same Apple account on another device. Tap Restore purchases in Settings if anything looks wrong.
Can I get a refund?
Purchases are handled by Apple. You can request a refund at reportaproblem.apple.com.
Can I turn off haptics, undo, or the no-pairs alert?
Yes, in Settings, along with the theme, large digits and high contrast.
