About this game
3Detris presents falling blocks as part of an experimental three-dimensional scene. The bundled Russian instructions identify freeware version 0.777 and distinguish the block controls from the viewpoint controls. You can play in the ordinary single view; the split stereo display is an optional visualization mode.
Press Enter for a new game. Number keys 1–6 control the blocks and Space drops the current piece. Num Lock pauses. The arrow keys move through the surrounding space rather than serving as the usual two-dimensional Tetris layout.
Backspace switches mouse control between the game field and the surrounding space. Page Up and Page Down change the viewing tilt, while the numeric-keypad plus and Enter alter the field’s tilt. Tab switches stereo and mono display. The bottom readouts report score, scoring rate and elapsed play time.

Quick tips
Use mono display first to learn the unusual layout.
