All sorts of turbot moves to play on 4s and 7s - a nice respite from bivalues! I noticed this interesting grouped move early on (4 had a nearly identical pattern).
Quote:
grouped x-loop(7) (7)r1c2 - r2c13=r2c6 - r13c5=r7c5 - r8c46=r8c2 - r1c2; r1c2<>7
type 1 UR(47); r1c5<>47
(It's probably easier to play the UR first but grouped moves are fun!)

Yes, 47s were the game................

Quote:
Performing the TYpe 1 UR47 first provides two sets of 6-cell Remote Pair (47), one of which results in r8c2=3 to complete the puzzle.
