Math game about swapping cards to get the result 21. Despite it being only a few cards, some of the levels were actually a bit tricky if you werent intending to brute force the solution. Simple, works, even if it could use some more bells and whistles and more ideas for a bit of a more unique game concept.

The solution is correct.

[Q] - [+A] / [-A]

10 - (11/-1) = 10 minus -11 = 21

Multiplying and division before addition/subtraction.

A cute game. Takes me back to school Arithmetic primers in a good way haha. 18's maybe a bit weak compared to other puzzles as the setup means that only the placement of one card actually matters. The other others can go in any of the remaining slots and still produce the same results.
