I'm pretty there's some wrong answers here. In the Spatial section, The Navigator is often wrong and doesn't display the correct answer as one of the choices. Please take a look and check the answers, I've come across this fault many times that I'm certain it's there..
I liked it a lot but now ads will pop up in the middle of games. They cover the entire screen. I get slow times because I end up clicking on ads and it's just annoying.
They really put effort in the problems you'll find here. And the support is great.( ...in case you get stuck)
