Boring math is history! Sumon, the magic formula for you to exercise your mind as you play addition games, has arrived to the App Store. Train your number skills with Sumon, a game for all ages, where Math operations turn into fun that will keep you entertained for hours on end.

The objective is easy: you have to tap the numbered boxes and put them together until they add up to the correct sum. As you clear levels, the challenge becomes greater. Choose your gameplay mode (classic, progressive or respawn) and become the king of addition.

Only the brightest and quickest minds will reach the highest levels.

It's all a question of practice. How high will you be able to go?

How to play:

1- Tap the necessary numbers to join them until they add up to the correct sum.

2- Clear the entire panel to move on to the next level

3- The more boxes you use, the more points you'll rack up / get

4- Points are multiplied for using many numbers.

5- The further the numbers are away from each other, the more points you will get.

What are you waiting for? Put your mind to the test!

Good game. It's definitely math related. Real nice, try it out if you like puzzles.

Would've gotten 5 stars if it weren't for the ads.

All math, no game

I love math, especially puzzles like sudoku. But this is just a pointless game. Maybe this "game" is good for kids needing to learn faster math skills, but not for anyone else.

Here's the "game" in description: Gives you a number (like 13), has a short timer, you have to click numbers that would add up to that, keep going until all numbers are gone.

Sound fun? No? That's because it's not. It could be classified as a teaching tool for the children that are addicted to their iPods that have poor math skills...but this is definitely not a "game". Do not get, ever.

Needs work

The game has a good concept & is a fun way to build up your quick math skills but it keeps using the same numbers over & over. Mostly just 11 to 15. Sometimes it even gives you the same number for 2 or 3 turns in a row without changing it. Never goes above 18. Needs to use higher numbers!!
