Move over, Candy Crush.
Meet your next addiction: Trivia Crack.
The app from Argentine company Etermax is topping the charts in both Google Play and the Apple app stores, thanks to the perfect coupling of useless trivia facts and some friendly competition against friends.
Here's how it works:
After downloading the app, players can choose to connect through Facebook or email.
They're then ready to start a game with a random opponent or a friend. Once a match is set, the first player will give a bright wheel, nicknamed Willy, a spin to decide which category they'll play first.
Trivia Crack has six categories, including science, entertainment, art, geography, sports and history. Each category has a corresponding character and answers are timed.
Answer three questions correctly and earn one of the six total characters needed to win a game or you can challenge an opponent for one they're holding. If a user answers incorrectly, it is then their opponent's turn.
The app also comes with a chat feature, allowing for plenty of friendly banter during the competition.
"Slowly draws you in and then won't let go At first I was like, 'This game ain't even that fun.'" a reviewer named Amy wrote in the Google Play store. "But for some reason I just kept playing. And playing... And playing. Now I'm considering checking myself into rehab for my Trivia Crack addiction."
Before you get hooked on Trivia Crack, a warning: If you neglect a game for more than two days, the win goes to your opponent.
