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

Sonic Eraser is a 1991 Sega Genesis release, originally distributed in Japan through the SegaNet service. It was developed and published by Sega, placing it among the many puzzle games that emerged during the console's peak years. The game borrows Sonic's familiar appearance but applies it to a falling-block format, a common trend at the time where popular characters were often used to lend appeal to different genres.

You control Sonic at the bottom of the screen, moving left and right to catch colored blocks as they fall. The main objective is to clear blocks by matching three or more of the same color, with Sonic himself acting as the cursor. Key mechanics include chaining combos for higher scores and managing the rising stack to avoid a game over. The pacing starts relaxed but escalates quickly, demanding faster reactions as the blocks descend more rapidly. It feels satisfying to set off a big chain, though the difficulty can become punishing without warning.
