This isn't a code, but a game of speed and dexterity (and a way to test if your calculator is a genuine Casio or a clone).
Exploiting firmware bugs by entering specific strings of fractions, matrices, and exponents to overflow the calculator's temporary memory (RAM). This unlocks hidden test modes or forces the screen to render pixels arbitrarily.
The process highlights the unintended programmability of “non-programmable” calculators and serves as a case study in firmware reverse engineering for embedded educational devices. casio fx991es plus games code repack

If the calculator freezes, you can reset it by pressing SHIFT + 9 (CLR), then select 3 (All), and press = to confirm. While not a true moving snake, users simulate
This allows you to generate random, glitched text that looks like a puzzle.
