Play Sonic Eraser (Japan) (SegaNet) [En by D v1.0] Online

Game Overview

Sonic Eraser is one of those weird little Genesis games that never left Japan—somehow, Sega decided Sonic needed a puzzle spin-off, and this is what we got. You’re dropping colored blocks (because of course you are), trying to clear them before they pile up. There’s a weirdly satisfying crunch when you erase a big combo, and the music has that classic early ‘90s Sega jingle vibe.

It’s not exactly a hidden gem, but if you’re into retro puzzlers or just curious about Sonic’s stranger side projects, it’s a neat time capsule. The controls are simple, though the difficulty ramps up fast—I got wrecked by level 3 the first time. Still, there’s something charming about its weird little existence.
