The goal is to make the sum of numbers in each row and column be equal to the number in the box.

What you have to do is to remove some numbers from the equation by clicking on them.

It sounds simple but requires a lot of thinking.

The board sizes range from 5×5 to 8×8. There are also 3 levels of difficulty: 1-9, 2-4 and 1-19.

1-9 means the numbers to calculate will range from 1 to 9.

There are 2 game modes: Classic and Endless.

In Classic mode you can choose which board size and difficulty you want to play

In Endless mode you will be given a puzzle with random size and difficulty.

Your total wins in any mode is saved.

Good game to all of you and do not forget to leave us a comment in order to allow you to know your opinion.

great game! would love hint option though

I love this game! I have trouble focusing sometimes, and being able to think in numbers gives my brain space to focus on what’s being said. I also love the different puzzles that are generated. My only critique is that I am absolutely stuck on a level (1363 on endless), and there’s no way for me to get help or a hint or anything and I’m dying here! update: reducing my rating to three stars, due to the multitude of issues with the app lately. Multiple buttons, including the button to play the actual game, are unpressable. I am also unable to click on the Facebook option to save my progress. And of course, still no hint option. And I’m still stuck.

Classic Button

The classic button doesn’t work, other than that, I love the game.

Classic still doesn't work

What's the point of making new play variations for a game when you can't play them?

Solid Game, Good UI

I found this game online and immediately downloaded the app-- the game generates good puzzles.

Ads don't auto-mute

Great logic puzzle, but I had to delete the app. Even though I went to the settings and muted the music and sound effects, an ad popped up during play with the sound on full blast. I can't have that in the situations where I would use this app. Other games apps I play auto-mute the ads when I mute the sounds in the app's settings.

Very fun

Cute maths/logic game that you can customize to be as easy or tricky as you like. Developers listen to feedback and fix issues promptly

Challenging and addictive

First played this game on Kongregate and was very fun. May be frustrating at times but is extremely rewarding upon level completion. Highly recommended to those looking for a math puzzle challenge

Very addictive. Great exercise for the brain.

Love it, except one thing

I figured out that tapping the sum squares shows the current sum as a pop-up (Try it and see). This is really handy, but after a while, it makes it too easy. (Dumb complaint, right? Just don't tap the squares!) Still, it makes the 8x8 levels a breeze, especially with 1-19. (8x8 with 2-4 is still a nice challenge, though, even though there are usually multiple solutions and trial-and-error is needed to solve, rather than just logic.) It's one of the first games I click on when looking for a quick distraction, and I've paid for ad-free on both iOS and Android, so hopefully that gives an idea how I feel about this game. Great job!
