Sumplete

What is Sumplete?

A number grid where each row and column shows a target sum, and you cross out cells until the remaining numbers hit every target. Famously prototyped with an AI assistant, then polished into a proper daily habit with sizes from gentle to punishing.

How to play

1. 1Compare each row and column total against its target sum.
2. 2Cross out the numbers that cannot belong, keep the ones that must.
3. 3Finish with every row and column matching its target exactly.
