How to play

Tips to get better
- Learn the single-combination sums: 3 in two cells = 1 + 2, 4 = 1 + 3, 16 = 7 + 9, 17 = 8 + 9; in three cells, 6 = 1 + 2 + 3 and 24 = 7 + 8 + 9.
- Where two sums cross, keep only the digits possible in both.
- Digits in a sum are all different: a two-cell sum of 10 can never be 5 + 5.
