Enigma is a brain-stretching puzzle game similar to Oxyd and Rock 'n Roll. The aim is to use your marble to open all matching pairs of the Oxyd stones scattered across each landscape, solving various puzzles and avoiding traps as you go.
Occasionally you will also encounter 'meditation' levels where you must control two or more marbles at once, your task being to manoeuvre each one into small pits on the floor.
The game has a large library of levels split across various styles so there's sure to be something for everyone. The download page has links to versions for Windows, MacOS and some flavours of Linux. - Prospero
