4=10

It's good game and Ad free but there is a big issue the difficulty doesn't go higher with your progress I feel it's random like level 20 is more difficult than level 50

I’ve had this game for quite a while now — no, I haven’t finished it yet. Level 374 with no hints!! Despite its seemingly repetitive nature, this game never gets boring. Even when I take a break for a few days, it’s always something nice to come back to. I highly recommend!

I’ve seen this game all over Reddit lately and am totally pleased with it. Ad-free, nice user interface, delivers on the premise with elegant simplicity. I’m captivated!

It seems simple at first. How hard can it be? Very. Makes you see basic math in a whole new way.

I used to do puzzles like this that I made on paper during high school and they were so much fun. This brings me back to that I highly recommend this if you like math.

Good for brain storming. But we need various type of mathematical skills. So we need variation

First game I’ve downloaded in 23 years and it’s addictive

I love this game. Beautiful in its simplicity, yet really engaging.

Great game. Took about a week to do all the levels. Really enjoyed it. Great for kiddies learning their math operations and old dudes like me as well.

This game has no ads! Completely interruption free so you can figure out you math questions in peace! I also love the little fireworks they set off in the background after completing a certain amount of levels!
