Play Diamonds 3D Online
Bounce a neon ball through a twisting wireframe maze, watching it ricochet off shimmering blocks as the whole playfield tilts under your mouse. Those deceptively simple angles will wreck you before the retro sound effects finish crackling.

Diamonds 3D was part of the MS-DOS Classic Games collection, though it didn't carry a specific release number. It was developed by a small team, and it fits right into that early 90s era of experimental 3D games, when developers were still figuring out how to make polygonal spaces feel interactive and fun. The graphics are simple, just wireframes and basic shapes, but they get the job done.
You control a small ball that you guide through a series of maze-like, three-dimensional levels. The main objective is to collect all the diamonds scattered throughout each stage while avoiding obstacles and pits. The signature mechanics involve navigating the ball across tilting platforms, using the mouse to adjust your view and the angle of the playfield to roll the ball precisely. The pacing is deliberate, almost puzzle-like, as you judge each bounce and roll to avoid falling off the edge. It feels like a careful balancing act where one wrong move sends you back to the start.
Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
