Let's see if you can prove it! ⌘ Compete with players from all over the world! ⌘ Make bids, take risks, and earn energy! ⌘ Get to the top of the leaderboard in Game Center! ⌘ Boost your knowledge of the topic by training offline! ⌘ Mind the time: if competitors have an equal number of correct answers, the victory goes to the one who has spent less time on guessing! Short competitions (lasting no longer than 1 min.) consist of 5 rounds. The winner is determined by tallying up the results of all the rounds. Be careful: the competitions are so gripping that you may find it hard to tear yourself away from your device! ;)
