01
The rules
- You see an N×N grid of numbers with a target sum beside each row and below each column.
- Tap cells to cross them out (delete them).
- The remaining (non-deleted) cells in each row must add up to that row's target.
- The remaining cells in each column must add up to that column's target.
- Every puzzle has exactly one solution — no guessing.

How to play here
Tap a cell to toggle it deleted (crossed out) or kept. Targets turn green when their line matches. Match all targets to win.
03
A starting tip
Look for a row or column where the target equals the total of all its cells — you keep everything. Or where the target is so low only one subset works. Extremes are free moves.

Solve a mini Sumplete together
Step 1/3:Row 3's target is 3. You could keep 1+2 or just 3 — but check column 2 (target 3): it already needs the 3 from this row. So keep only the middle cell (3). Delete the 1 and 2.
Tap cells showing 1 and 2 in the bottom row.
