Great way to pass time and still feel somewhat productive. I remember being introduced to a game of a similar premise called "Just Make 10" by a teacher in elementary school, except it was a physical card game. I'm in university now, randomly remembered those times and dug through the app store before finding this game. Exactly what I was looking for. No gripes with this game at all, it's relaxing and stumps my sleepless brain at times. The soft haptic is also incredible, but that's just me :)

Thank you for the review and sharing your story. It is interesting to hear how many (re)connect with basic math. I wanted to make basic math fun/interesting, without cheap tricks like gems and badges. Help people dive into the numbers and see the patterns. Too many people fear math, usually because it is taught in a bad way IMO.

The game is dead simple... 4 digits, 4 operations, make it up to 10. There's literally nothing else but damn it keeps you engaged no idea how. Has 500 levels and 0 ads. The background animations are really subtle and interesting everytime you clear a level. One of the best games I've played in quite a while.

Congrats to the Devs, because it's an ad free game and it's pretty simple and well done. Howevery o have a couple remarks. I find it difficult to drag and drop the symbols to place them between the numbers...it seems that I have to always wait a fraction of a second more before releasing my finger. I also find it not challenging enough. I'm at puzzle 200 and I almost always spend more time in the drag and drop, rather than thinking. It should be possible to jump to harder levels.

Hi Cláudio and thank you. A new version, 1.0 5, has been deployed to address these problems with drag and drop. Also offering a tap and tap mode. Enjoy.
