Number Merge 10 and the rectangle sums that clear the grid
In Number Merge 10, you drag a rectangular selection across the board and clear every tile inside it when the numbers add up to 10. That exact-total rule gives each move a concrete test: a tiny cluster might vanish at once, while a wider frame only works when every value inside fits the sum. It runs in your browser with no download or no signup, so you can start scanning the grid right away.
Levels that make every 10 harder to spot
Each cleared board pushes you into the next level, and the layouts get denser as more numbers are packed into the grid. Instead of hunting one fixed pattern, you have to read rows, columns, and wider rectangles quickly enough to catch the combinations that land on 10. A clear run depends on spotting the right span before the board fills with leftover digits.
It also connects naturally to logic games, because the whole challenge is about reading the board and testing sums instead of matching colors or symbols. If you like exact-total puzzlers, Sum Master feels close for the same reason, while Number Match shares the quick number spotting and board scanning. The drag-based input makes the game easy to handle on a phone or laptop, and the arithmetic stays front and center.
When a row contains several small values, short rectangles are worth checking first; when larger digits appear, wider selections may be the ones that reach 10. That mix of tiny and broad areas keeps every board from feeling identical, and it gives you a clean reason to look at the same grid in a few different ways before you commit to a move.
