Awesome game!

This is a really clever idea! It is smooth and easy to play. I like that there is no penalty for putting the wrong number temporarily in a box while you try to solve a puzzle. I love this game! It is amazing it only takes a tiny bit of space on my phone. Very well made! Thank you for making this game!⭐️⭐️⭐️⭐️⭐️
There is just one minor issue where sometimes when I find a solution it doesn’t say “correct” even though it is one of the correct solutions. I have to find another/other correct solution/solutions until it is the one that the game recognizes.
