Tetracopter 12 is a continuation of the HeliPrism series of edge turning prism puzzles. It is based on a four-sided prism, and uses pillowing and curved cuts to minimize the number of pieces, resulting in a slice pattern very similar to the previous Tricopter 9 puzzle. Due to the octahedral nature of the core, this puzzle is not jumbling (unlike all the other HeliPrism puzzles), although it does shape-shift and bandage constantly.
