With one set of numbers, you have to solve 12 different problems, and that is both remarkable and challenging. I was instantly convinced by the game's simplicity and efficiency. Yet, when my friend pointed me to Quento, I installed it, put my head down, and didn't raise it for another three hours. There are no settings (only a mute button), no various board sizes, no rankings, no levels, and none of the extras that usually entice gamers. It's straightforward enough that any kid or adult should be able to play and enjoy it. Collect all stars and you can move to another board. There are three stars to collect in four difficulty levels that differ by how many numbers are required to get the total. Start with a number, swipe to an operator, and then back to another number in order to obtain the total asked by the game and earn a star. Quento gives you a 3x3 board consisting of five numbers and four operators.

For now, the score to beat is 3.35 seconds for solving 10 questions.

A detailed statistics page keeps a tab on your efficiency and best results, and connects to Google Play Games for Leaderboards and Achievements. The more you solve and score in any of these, the higher your level and rank are. Math Effect has a time mode, a fixed equation one, and an unlimited mode with five seconds for every equation.
