There are tons of correct answers that they mark wrong (eg "What is something you find in a cave?" Fossils was incorrect), there are tons of 30s+ unskippable ads, they try to force you to spend in game currency on a mini game, and WORST OF ALL you are only playing against bots. Left a game for 20 minutes and came back to finish the same game. That would not have happened if it was PVP. It is a great concept with lots of potential. Shame that this company doesn't deliver what is advertised
