4=10

Would highly recommend for kids learning their arithmetic functions to see how numbers can interact with each other. Quick brain teasers.

And has no ads. How nice is that?

At the first few levels, it seems pretty easy to get 10 and you will fly through those levels, but for me after level 300+ it gets really challenging and makes you think deeper and more critical about how to create your equation. Great brain game!

This game is really well made and I appreciate not being bombarded with ads every 3 seconds, I can also play this game offline if I chose to do so. Very well made

It’s worth it for kids, gives them a good training in calculus. It’s free with no adds. A big thank you to the developers.

Surprisingly interesting and addictive

There is no difficulty progression. It feels like they went for a high number of levels instead of sorting them by difficulty. I was hoping after solving 20 there would be more challenges. If you know your order of operations, this gets boring in 5 minutes no longer providing any challenge.

Having a well-made simple game free without ads is like winning the lottery in today's e-culture. This is an (if not the only) example.

very calmy and cool, no ads so you can stay in the moment
