Play Sonic's Edusoft (Unknown) (Proto) Online

Ever imagine Sonic trading his sneakers for a schoolbag? Sonic's Edusoft is this bizarre, half-finished Master System prototype where our favorite blue hedgehog suddenly has to solve math problems between platforming sections. It’s like someone took a ’90s educational game and slapped Sonic into it—awkwardly, but with charm.

The physics feel a little off (probably because Sonic wasn’t built for stopping to calculate fractions), but there’s something weirdly endearing about watching him bounce between equations and springboards. The graphics are pure early-’90s SEGA, all bright colors and blocky fonts, like a lost episode of Sonic Schoolhouse that never got finished.

Honestly? It’s more fascinating than fun—a "what if?" relic for die-hard Sonic fans or collectors who love digging up obscure prototypes. I wouldn’t call it good, but I also couldn’t stop playing just to see how weird it got. If you’ve ever wanted to see Sonic awkwardly pause mid-run to answer a multiple-choice question, this is your game.
