The Next Tetris: On-Line Edition for the Sega Dreamcast is a classic puzzle video game with a twist on the traditional Tetris formula. Released for online play, this title introduced new gameplay mechanics with varying block shapes and a special cascading feature that allowed blocks to fall into gaps below, creating new strategic possibilities. It maintained the genre's addictive tile-matching gameplay, where players aim to clear lines by fitting geometric shapes together. With competitive online multiplayer modes, this edition added a new level of challenge and replayability to the iconic puzzle genre.
