TetraVex



TetraVex is a puzzle computer game, available for Windows and Linux systems.

Gameplay
TetraVex is an edge-matching puzzle. The player is presented with a grid (by default, 3x3) and nine square tiles, each with a number on each edge. The objective of the game is to place the tiles in the grid in the proper position as fast as possible. Two tiles can only be placed next to each other if the numbers on adjacent faces match. Thus, in the final layout, each tile can only be in one specific spot.

Availablility
Tetravex was originally available for Windows in Windows Entertainment Pack 3. It was later re-released as part of the Best of Windows Entertainment Pack. It is also available as an open source game on the GNOME desktop.
