How to play TenSum

A 10x10 grid of digits: select groups of adjacent numbers that sum to exactly ten and they clear from the board. Longer chains and rapid consecutive clears score higher through the combo system, and clearing the entire board earns a perfect-clear bonus. A counter shows how many distinct tens remain, so you always know when a board is still alive.

Tips & strategy

• Clear awkward digits like 7s, 8s and 9s early - they need specific partners (3, 2, 1) that grow scarce late in the board.
• Longer combinations score more than pairs: a 1+2+3+4 chain beats 6+4 even though both make ten.
• Watch the remaining-tens counter before committing - sometimes one greedy clear kills the only path to a perfect board.

TenSum FAQ

Do the numbers have to be adjacent?

Yes - a selection must be a connected group of neighbouring cells whose values total exactly ten.

What is a perfect clear?

Emptying the entire board. It pays a large bonus on top of your combo score and is the mark of a truly solved board.

How does the combo work?

Consecutive clears in a short window build a multiplier - keep finding tens without long pauses to hold it.
