wwwmwww@IronManMark44 Yes, I have met Oskar face-to-face I believe a total of 4 times over the last 4 years at events like International Puzzle Party (IPP) and Gathering for Gardner (G4G). I own a number of his puzzles. I have collaborated with him on a number of his puzzles, Mosaic Block, Real 6x6x6, and Ring Bracelet come to mind. And he and I have both been regular posters in the forums at twistypuzzles.com for years. I've been on there since 2004, Oskar since 2009. Though Oskar has been designing puzzles for decades. I got into designing about 5 years ago.
wwwmwww@IronManMark44 Yes, the Doctor Cube only allows slice moves. The Mixup Cube allows both slice and face turns. On the Doctor Cube opposite pieces always remain opposite so there are really only 9 pieces that need to be solved. You can think of them as 3 rods through opposite faces and 6 rods through opposite edges. The corners can not be scrambled. The Mixup Cube as 6 face centers, 12 edges, and 8 corners all of which need to be solved. And no... not rude at all. I know Oskar well and I appreciate those that stick up for Puzzle Designers. I know your heart was in the right place. All is well.
wwwmwww@IronManMark44 Are you thinking of Oskar's Mixup Cube which itself is a copy of the Makarov's Cube?
If so, you are wrong. The Doctor Cube and the Mixup Cube are not the same puzzle. The Doctor Cube is much easier to solve.
wwwmwww@Rover36 There are 2 links above. One is to the original Untouchable 11 puzzle which uses the 11 unfoldings of a cube. That puzzle has 7 solutions and has a different green piece then my puzzle. The puzzle you see here and in the other link is the Untouchable 11 Master Challenge. This is a different subset of the hexominos and yes it uses a different green piece. This puzzle only has 2 solutions so its a fair bit harder then the original, which is already a very hard puzzle. I have off and on been looking for a subset of the hexominos which only has a single solution to this puzzle but as yet a set with 2 solutions is the best I've been able to find.
