Another math game with interesting take on countdown. I am more surprised by the fact that you made it with react and typescript lol. You must be amazing front end developer lol.
I can see myself playing again and again.
Feature suggestion: Display upcoming cards (this would allow to strategize even more, like if current value is 18 and there is divide by 3 and upcoming card contains subtract 6, then we could use divide by 3 and wait for subtract 6 to show up)
