Quento is a delightful little math puzzler without ads that is fun for kids and adults. Over the past 8 years it has been played all over the world by children, parents, students, teachers and basically anyone during commutes, in schools, on camp sites, during lunch breaks, at offices and in bed before going to sleep. Enjoy endless rounds of quick play, a unique daily challenge, different sets of numbers and a zen mode. And with the special “Quento for Schools” mode, students can play together in class, in smaller groups or engage individual challenges.   How does it work? Simple! Quento gives you the solution to a sum and you’ll have to do the math. To play, just swipe from a number to a + or – and to another number again. Stars are earned when the sum adds up to the challenge above and before you know it you’ve progressed a round!
