About Mathlip

Mathlip hands you a grid of numbers that is already full but in the wrong order, plus a set of constraint chips above it: this group sums to 128, these cells descend, these multiply to 5082. Each chip shows its target and how close you are. You drag or tap two tiles to swap them, and you keep swapping until every chip is satisfied at once. Tapping a chip lights up the cells it covers, so you can see which tiles it depends on.

The grids run from a 3x3 tutorial to 7x7 Expert boards with up to nine constraints. There are eight kinds of rule: sum, unique, sequence, odd or even, ordering, arithmetic sequence, product and divisibility. Harder grids layer several of them over the same cells, so one swap can fix one rule and break another. There are no timers that end the game, no lives and no account; a move counter and clock are shown, and there are three hints per puzzle by default, with undo and redo.

The daily challenge is one puzzle a day, the same for every player. Monday's is gentle and the week climbs until Sunday's is an Expert grid, and solving daily keeps a streak. The listing is clear about the cost: the first week of dailies is free, and after that the daily lives in a one-time pack called The Daily Grind. The app has 35 free puzzles and 180 more in four one-time packs, with no ads and no subscription.

Mathlip is made by XpMind and came out on the App Store in April 2026. It works offline and has a colorblind mode with letter markers. It suits players of KenKen, Kakuro and other arithmetic logic puzzles who want a different mechanic: rearranging rather than filling in.

How to play Mathlip

1. Open Daily Challenge to get the day's grid and its constraint chips.
2. Tap a chip to see which cells it covers and how far it is from its target.
3. Swap two tiles by dragging one onto the other or tapping both.
4. Keep swapping until every chip is satisfied at the same time; use undo or a hint if you get stuck.
5. Solve it to keep your streak, and come back the next day for a harder or easier grid depending on the weekday.

Tips

• Start with the most restrictive chip, such as a product or an ordering rule: it fixes the most tiles.
• Tiles covered by only one chip are free to move without breaking anything else; use them to fine-tune sums.
• Watch the running totals on each chip after every swap, not only the one you are working on.
• Expect Monday to be easy and Sunday to be Expert: plan longer sessions for the weekend.
