Play Number Merge 10 unblocked

Number Merge 10 is a math puzzle with one rule: make 10. Select a rectangular area of the board, and if the numbers inside add up to exactly 10, they're all cleared. It's easy to learn, and the fun is in spotting the boxes that work, like a 3 and a 7 side by side, or a 1, 2, 3 and 4 packed into a square.

How to play

• Drag to select a rectangle of numbers.
• If they add up to exactly 10, every number inside disappears.
• If they don't, look for a different group.

Tips

• Start with pairs: 1 and 9, 2 and 8, 3 and 7, 4 and 6, 5 and 5.
• Bigger rectangles work too, as long as the total is exactly 10.
