A cute critter by the name of Fitz is on a quest to gather gems from an ancient city. Each room in the city presents a brain teaser which must be solved to get all of the gems and safely to the exit. This is a puzzle game for people who like really thinking about their puzzles.

New Game mechanics is the best surprise in this game:
- game board is moveable part of the game
- tokens inside the completed set are moving from path to path instead of from field to the next field
- token pushed out of the game board immediately re-enters from the other side of the same row or column (we say On-Torus moving).
Tokens are transparent, which makes the game goal reflexively obvious, i.e. one token set fits one pattern colour.

Click and drag: Token is moveable inside of its belonging row or column. All tokens are floating in one single layer over the game board.
Game Board: Background fields are arranged in unique CMean pattern of 3x3 fields. Pattern consists of 4 pathways that are painted by different colours.
Tokens are divided in 4 different sets, where one-set is corresponding to one-pathway.
Yin Yang is the token and the background field simultaneously.

This highly addictive game will keep you thinking for hours.

Plus - an optional Internet gaming mode is included.

Oktagon comprises two separate octagonal puzzles. In the first, you must rearrange a set of four to eight irregular shapes to form an octagon. This is based on a puzzle in our shareware game Uncle Julius and the Anywhere Machine. In the second puzzle, you must rotate six concentric octagonal rings until all have the same orientation. The catch is that the rings are linked, so that rotating one also rotates one or two others.
