About the game

OSIRIS is a classic DOS puzzle game that stands out through its straightforward logic and distinctive style. It is aimed at fans of vintage thinking games who still enjoy discovering these older releases today.

Our release includes a loader with a legacy protection fix for the game. To keep things appropriate, the download is intended for owners of the original game; you start it through LOAD.COM in the installation directory.

D.O.S.I. says

OSIRIS does not just place stones on a board; it turns them into a compact tactical puzzle with a very early-90s attitude. MobyGames lists it as a 1993 DOS release from Pixlers Entertainment, published by Boeder Software GmbH, and describes a pyramid-shaped playfield with move limits and a nasty little struggle for the center. That setup is the whole charm: the rules are easy to grasp, but every careless move can come back and bite you two turns later. The way it sits between puzzle and strategy also fits the game’s clean, board-game-like structure. If you enjoy old logic duels, this is the kind of design that still snaps into place nicely.

The DOSGAME.AT loader smooths out the old protection routine and includes the level codes, so getting the game running is less about wrestling with aging copy checks and more about actually playing it. For an archive release like this, that matters a lot: the game itself stays intact, while the path to launch it becomes far more practical. Since the download is meant for owners of the original, the whole package stays in the right lane. In short, OSIRIS gets a fresh runway without losing its stubborn little puzzle heart.
