In a world dominated by a currency known only as "IQ points", it's up to you to climb the leaderboards and take the top spot by reading as much as possible! To start earning some points, you'll need to use the book found within your inventory. Then, once you've completely filled your IQ storage, you'll need to head over to the marketplace where you'll get to exchange your points for coins.
When you've earned enough and are ready to splash some cash, you'll need to visit either the book or upgrades shop. The book shop, if you haven't already guessed from its name, has a range of different books that yield a higher rate of IQ points. The upgrade shop on the other hand will allow you to unlock even larger amounts of brain capacity, meaning you'll spend less time at the marketplace and more time reading your favorite books!
