# Fridays's Blocking Donimoes Problem

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 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, Wednesday's, and Thursday's problems would make a good warmup.

Today's problem is the grand finale, using a complete set of double-six dominoes! Good luck, and post your solution as an answer.

This was tricky! (The top right corner is particularly difficult to manoeuvre, avoiding putting the 2's and 1's together. The 0's and 1's at the bottom also pose similar problems...)

A winning set of moves is as follows (move sets in brackets can be carried out in more than one order):

24U, 00U, [54L, 05L, 14U, 21U,] 02L, 02L, 02L, [21D, 35D, 14D, 26D,] 22R, 04R, 51D, 51D, 51D, [04L, 65L, 22L,] 26U, 03L, 14U, 21U, 02R, 05R, 54R, 00D, 24D, 35U, 02R, 02R, 21D, 14D, 65L, 03L, 16L, 16L, [26U, 35U, 14U, 21U,] 02L, 02L, 64U, 64U, 43R, 06R, 01R, 11R, 66R, 13R, 63D, 52D, 44D.

In diagram form (read along each row):

56 moves in total!
