My daughter loves it. The speed you need to get 3 stars for progress is a good challenge. I dont think the time needs extending on the levels because quick thinking and quick math is important. She does struggle with some of the less common pop ups and doesn't know what to press to continue but otherwise has no issues with the challenges.

Good practice although very very repetitive (I guess that's the point). Currently won't let us past level 56 despite getting every question right. We've tried it about 6 times and it only gives one star so have to repeat the level. It seems to be impossible to get 3 stars (I'm a maths teacher and even I can't get them doing it super fast and 100% accurate) but now we are completely stuck. Help please!
