Rullo is a minimalist math puzzle game where you have a board full of numbers.
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.

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.
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
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
