Having solved and studied the Tuttminx previously didn't hurt my mixed martial art match with the Icosaix. Drawing from some methods and algorithms I learned with the Tuttminx, I had the Icosaix pinned in about 3 hours.

The only really disappointing thing about it mechanically is that you can rarely make counter-clockwise turns. Most times you must make two clockwise turns when you want one counter-clockwise turn. I'd really love to see Oskar come out with a version 2 that fixes this problem.

It's a great challenge and fun solve. And now... I hear Eitan's Star calling my name.

Love the packaging, extremely impressive out of the box, nice weight and feel as well as aesthetically eye popping, especially once scrambled. Really glad it came with stickers already on, though I guess some might like to sticker it themselves, The real issue and why I cannot give 5 stars is the mechanics. Faces generally turn clockwise well but counter-clockwise almost always will jam or result in popping of the corner petals. I had to make two clockwise turns to effect counter-clockwise about 80% of the time. Not sure if lube or tuning can help. That said it was incredibly satisfying to finally solve this marathon monster! As the largest and most complex of the Platonic Solids, I felt it was a must have for my cube collection. Kudos to Oskar!
