"At last! There are dozens of maths apps out there for this age range & they're either all animation but no substance or just very dull. This strikes the right balance. It's cute & straightforward but it's genius is in its addictive quality. Maths answer to Candy Crush. My (nearly) 7 yr old loves it & it's improved her ability to quickly find the answers, when she'd be slowly counting up with her fingers before. There's a lot of drivel out there. This hits the spot. Highly recommended!"
