Getting started
Swap number tiles until every rule on the board is satisfied. Use the tutorial to learn what each clue means, then work through the free puzzles. There is no countdown timer or lives system.
Daily Challenge access
Your first seven days of Daily Challenge access are free. Continuing after that requires the one-time Daily Grind purchase, which also unlocks Endless Mode. The four handcrafted puzzle packs are separate purchases; a puzzle pack alone does not unlock ongoing Daily Challenge access.
The challenge changes each day and grows harder through the week. If access looks wrong after buying Daily Grind, try restoring purchases.
Restore purchases
- Open Mathlip and enter the puzzle store from More Puzzles.
- Choose Restore Purchases.
- Use the same Apple Account that made the purchase, with an internet connection to the App Store.
Restoring an existing purchase does not charge you again. It restores your purchased access; it does not recover deleted local puzzle progress.
Purchases and billing
If a product will not load, check your connection, close and reopen Mathlip, and try again. Prices are shown in your local currency before you confirm a purchase. For refunds or Apple Account billing problems, visit Apple Support.
Your puzzle progress
Game statistics, completion records, and settings are stored locally on your device. Deleting the app removes this local data. Restoring purchases restores ownership of paid content, not your previous puzzle history.
