Double Trouble

Double Trouble - by the legendary Larry Nichols - who invented the first 2x2x2 Rubik's Cube. The Grabarchuk Framily is hosting this little gem. It's an online puzzle that resembles the 15 puzzle. Here's the catch: you must shift 2 tiles at a time.

It would be great to have a mechanical version of this. But this online version is great anyway.


  1. It seems quite different from a regular sliding block puzzle. It didn't "grab" me and I found it rather confusing. But perhaps spending some more time with it ...

  2. It's extremely difficult! I have not solved it - yet!
