I am stuck here at Sumplete.
I have tried looking for numbers that must be used/must not be used using https://combinationsumcalculator.com/ and all of them are either not used in all combinations (when I try to achieve a value by adding) or used at least in one combination when I sum the whole row/column and try to subtract to reach the target value.
Some of my techniques so far:
- if the target value is low (e.g. 4, you can exclude all higher values).
- if you need something like 8 and you have 3, 4, 5 and 6 you can exclude 4 and 6 because they can never be combined with something that results in 8.
- exclude single odd values. If the target is 12 and you are sure about 6 (e.g, 2 + 4 or 6 alone) and one of the values you have is 3 and that is the only odd value, you can exclude that because you can never combine that with something that results in an even value
The goal of this game is to pick the numbers that add up to the target number outside of the grid.
Trivia: it is ChatGPT who "developed" this puzzle game, although it is more or less a copy of one or several existing games.
