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.
Good game to all of you and do not forget to leave us a comment in order to allow you to know your opinion.
-We released two new modes: The Expert Mode! where you need to play with the 4 operators and Beat the clock! where you earn stars based on the time you take to solve a grid. The times have been minutely studied so that they are achievable but challenging in a same time
-We improved some buttons (leaderboards)
-We are waiting for your suggestions to continue to improve the game or if you have ideas for a new mode or any new features

classic won't open but still very fun!
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 still doesn't work
What's the point of making new play variations for a game when you can't play them?
