About Number Merge 10
Number Merge 10 is a clever math puzzle that swaps the usual tile-sliding mechanics for something far more inventive. Instead of matching colors or symbols, you draw a rectangle around any cluster of numbers on the grid — and if those numbers sum exactly to ten, the entire selection vanishes. The challenge is surprisingly deep: small rectangles are easy to plan but clear the board slowly, while larger selections demand quick mental arithmetic and sharp spatial awareness. Each successful clear reshuffles the surrounding numbers in ways that demand constant reassessment, making every move feel like a small puzzle inside a larger one.
How to Play
Drag to select a rectangular region on the number grid. If the total of all numbers inside equals exactly 10, they are removed and you score points. Plan your selections carefully — overlapping and chaining clearances earns bigger combos. The game ends when no valid rectangle of ten can be found on the board.
Tips & Tricks for Number Merge 10
- Look for lone 9s or 8s first, since pairing them with a 1 or 2 guarantees an easy clear to open up the board.
- Larger rectangles with many small numbers can hide a sum of 10 — scan rows of 1s and 2s for hidden opportunities.
- Avoid clearing isolated corners too early; keeping numbers clustered gives you more rectangle options as the board fills.
