📚 Game Guides: games picked by genre, one page each
What is Correct Math?
Simple addition and subtraction sums appear and you choose the result from three options. Thinking time is short, so being right is not enough on its own. It fits nicely into a short break when you want mental arithmetic practice.
How to play
A sum sits at the top with three answers underneath it. Tap the correct result and you score a point and move straight to the next question. Every question has a short window, and the round ends if the time runs out or you tap a wrong option. Your aim is the longest error-free run and the highest score you can reach.

Tips
- Look at the units digit of the sum, because on most questions only one option ends with that figure.
- In subtraction the result can never beat the number on the left, so drop the big options at a glance.
- When you are unsure, guess and move on, since waiting burns as much time as a wrong answer.
