Rotational Gravity Puzzles
by Pantazis Constantine Houlis

Rotational Gravity (RG) Puzzles are a new breed of puzzles which use change of placement as well as mathematical rotation of pyramid-pieces inside a hermetically closed sphere. Depending on their theme, they can be very easy or very difficult to solve.

In 2008, MindStrat Puzzles mass produced themes based on the original Cubedron design made by Pantazis C. Houlis. Many more themes followed, such as the Aquadron, the very first mathematical puzzle that used water. The Aquadron is so elegant, that once someone sees it, it is very difficult to forget! Besides the cubic design, there are more puzzles based on rotational gravity, such as the tetrahedral design based on the narcissistic Puzzle Ninja, and the Krystalledron based on the Icosahedron.

In 2011, Drumond Park produced the Oginov, using the Cubedron's cubic design and is currently being sold to many famous retailers, such as Harrods and Amazon. More updates (and photos) to follow in the next weeks!

There have been a few professionally made videos released since the launch of the product in August 2011 (see below).
