Best for ages 10–16
Easy Mental Math Games
Looking for mental math games for kids that start easy and build up gradually? Mind Games is best for ages 10 to 16 — the first levels use small numbers and simple addition, making it a gentle on-ramp for building speed and confidence with basic arithmetic, whether you're a student, a parent looking for practice, or a teacher previewing it for class.
It's a free math puzzle game that runs right in your browser. No download, no account required to try the example below.
Try one challenge
Which two of these numbers add up to 15?
4 9 6 11
Reveal answer
4 + 11 = 15
That's the idea behind every early level — pick the numbers that add up to the target. As you go, the numbers get bigger and the puzzles ask for three or four numbers instead of two.
Frequently Asked Questions
What age group is this for?
The games are best suited for ages 10 to 16, though the earliest levels are simple enough for younger kids just starting arithmetic, and the difficulty settings let older students find a comfortable challenge too.
Does it require an account?
Yes — a quick free sign-up (email or Google) is needed to play, since it's also what saves your level progress and stars across sessions and devices. There's no cost and it only takes a few seconds.
Can students play on a school Chromebook?
Yes. Both games run in any modern web browser, including Chrome on a school Chromebook — there's nothing to install.
How long does one round take?
Most early levels take under a minute. Timed levels add a countdown (typically 40 to 65 seconds depending on difficulty), so a handful of rounds fits comfortably into a five-minute break.
Is it free?
Yes, both games are completely free to play.
