Buy at your own risk. This guide does NOT cover anything related to calculation, graphing, and which calculators are the best at this. Rather, this guide DOES cover the calculators that have the most EOP/hack/homebrew potential. Of course, this list can still influence which calculator you buy for it's purpose of calculating, but that topic is something that you decide on your own.

On this guide, you will find what is essentially a “ranking” or “priority” of calculators, based off of the non-calculation things you can do with them. Whether it's hacks, games, homebrew, exploits, or alternative operating systems entirely, this guide demonstrates the calculators that have the most.
