I've designed a set of dominoes puzzles that I call Donimoes. You slide the dominoes like the cars in Nob Yoshigahara's Rush Hour puzzle, always along their long axis. The goal of Blocking Donimoes is to slide all the dominoes into a rectangle, without sliding any matching numbers next to each other. See Monday's problem for complete rules and and an example solution. Tuesday's and Wednesday's problems would make a good warmup.

Today's problem is a little bigger and a little harder. Good luck, and post your solution as an answer.

If you like this puzzle, watch for one more problem tomorrow.
