Big Brain Simulator is a simple, but no less interesting and addictive Roblox clicker in which your goal will be to increase your character's IQ. By reading books you will increase your IQ, which you can then convert into IQ Coins, the local currency needed for all upgrades.

To facilitate the process of progressing in the game, especially from the very beginning, we recommend that you redeem Big Brain Simulator codes, the list of which we have collected below. Each of the codes will reward you with a bunch of freebies, both currency and other equally useful and important stuff, so don't neglect it.
