Hi there, thank you for posting your query to Helpowl. I would be happy if my answer solves your problem.
It's not possible to play a game on Casio FX-991ES.
A lot of people own an FX-991ES, but I've found that very few of them realise how powerful this unassuming little calculator actually is. Here's a (not entirely comprehensive) guide to getting the best out of the Casio fx-991ES. The guide assumes basic knowledge of how to get around the calculator (changing mode, changing from degrees to radians, memory etc). For more information, consult the manual.
