Initial setup required registration, which is annoying enough, but also it is buggy. Wouldn't let me register with my email (just sent me back to login), and when I tried to login with a third party, app just spun a circle for 5 minutes and never went anywhere so I gave up. Too bad because we have this game on a tablet and it is fun. (This review was on a Samsung Galaxy S21 FE 5G.)

I bought this app a while ago and loved it for home school, but now I'm having trouble re-downloading it. Trying to sign in isn't working as well (forgotten password link never sent to email). It looks like if even if I bought it I'll have to buy it again. There are so many one star reviews on here regarding glitches, freezing or even being charged double and not being refunded. It's too bad, because it was great when we used it originally. Don't want to pay for it again - it's too expensive.

I paid for this game when it was Dragon Box. Now, when I try to open it, I can't get past the screen that asks if I already purchased this app through dragon box. Nothing on the screen reacts when tapped. This was an amazingly fun game when it functioned. Kahoot destroyed it.
