RemTris v1.0 is a 1996 freeware DOS puzzle game created by Remi Veilleux of the demogroup INCa Master. It is a fast, polished Tetris‑style game featuring two gameplay modes:

• Standard Mode — classic line‑clearing rules

• Chain Mode — a unique recursive chain‑reaction mechanic inspired by Columns and Dr. Mario, allowing multi‑stage collapses and line clears beyond the usual four

RemTris supports two‑player competitive play, where clearing multiple lines sends penalty lines to the opponent. The game was originally conceived as a network‑enabled Tetris clone (then called Netris), with possible modem/network support planned for future versions.

The package includes full credits, system requirements, and gameplay instructions. Distributed as freeware; no known bugs were reported at release.
