• Year: 2016
• Original Price: $0.00 USD
• Current Price: No Data

This puzzle is similar to the previous Tricopter 9DS puzzle in that the jumbling cuts have been moved deeper, to a position 1/3 along the edges of the shape. However, this puzzle is also similar to the previous Tricopter 9SD in that the non-jumbling cut have been moved to a deep position, going through the origin of the form. As with all the previous Tricopter puzzles, moves on these two axes types can be combined in either order, allowing the puzzle to become fully scrambled.

This is arguably the most complex puzzle in the Tricopter series, featuring stacked axles, floating axles, a cheese core, and the highest part count for this puzzle series. Unfortunately the geometry is very unstable, and the puzzle is highly prone to popping apart, making it virtually unplayable.
