Plastris

Plastris is a Finnish Tetris clone from 1996 whose original FILE_ID.DIZ cheerfully declares it "simply the best Tetris clone ever made". That may be a stretch, but for a shareware title from the home-computer scene it offers a lot: a single-player mode, a two-player mode, and even a duel between two PCs connected by a serial cable.

The falling blocks are joined by special pieces that liven up the classic rules, the action plays out over nice backgrounds, and owners of a Gravis UltraSound card get sound as well. The in-game texts come in both English and Finnish. Polished little games like this circulated on Finnish BBSes throughout the 1990s, yet remained almost unknown abroad and are still overlooked by international retro sites.
