I had a difficult time with this one. There was a Hidden UR on 46; r5c1<>6, r5c5<>4. After that I saw nothing so I finished it off with Medusa, my technique of last resort.
Who or what is Patrice and why does the puzzle have two numbers? |

Patrice is a player in the Patterns Game on the Players' Forums, and he might not appreciate being referred to as a "what." As to the two numbers, the first is the game number, the second is the entry number for the puzzle within that game. |

Look for a hidden quad.
Hint: usually in a blank row column or box.
been so long since I've seen one I missed it.... |

| After trying it again on Draw/Play, and playing the Hidden UR, I found a quint in box 9 which finished it off. |

yes, quad is rare
and i especially liked Patrice's puzzle because i
needed a triple before reaching the quad |
