How to play Sumplete

Sumplete is a logic-based number game recently created in collaboration with ChatGPT!

Sumplete is inspired by Sudoku, Kakuro, and Hitori, but with a twist.

In Sumplete, the twist is that each row and column also has a "sum clue" associated with it. This clue tells you the sum of the numbers in that row or column. For example, if the sum clue for a row is 21, then the numbers in that row must add up to 21.

By default, every number on the grid is an "unknown" state. Your goal is to identify which numbers to delete and which to keep to ensure that the sum in each column and row matches its corresponding "sum clue".

4
Deleted
5
Keep

To mark a cell as deleted, click or tap once and you'll see an X.

To mark a cell as one you for sure want to keep, click or tap again and you'll see a green circle.

Click or tap one final time to reset to "unknown" state.

You'll need to keep track of the sums of each row and column as you go along to make sure you're on the right track.

Once all numbers on the right and bottom of the grid are lit up, you’ll have won the game!
