Love this app. Loved the old one & love the new one. Great fun questions, my kids & I love to play. Great to play when waiting for coffee or at the doctors. I started with the free version but had to buy the full version & I never purchase apps!

I like it

Trying to sharpen my skills for work trivia and thought I’d give this app a go. I like it because you are only competing against yourself and the commentary is positive.

Great lite experience!!!


The control of adverts in this lite version is great no need worrying about watching the full advert !!! Looking forward to the premium
