From game #169 this puzzle has some special properties

Code: Select all
..1...2...3...4.5.6.......7.....5.3.....2.....5.8.9...7.......6.4.5...8...2...1.. ED=9.3/9.3/3.4


Remove the second "5" and UA of size 61 appears

Code: Select all
59.687.438.721.6.9.2495381.216.459.89783.15644.3.6.721.8513249.1.9.763.236.498.75 #U61
..1...2...3...4.5.6.......7.....5.3.....2.....5.8.9...7.......6.4.5...8...2...1.. #pseudo-puzzle
                              - *


The UA covers all non-givens but one, marked as "-".

Further, the same pseudo-puzzle has 18 solutions and one more of them has U61 too. It can be covered by "6" from the pattern, but this leaves some other UA unhit.
Below are details for the 18 solutions of the puzzle. The valid solution is #4, other with U61 is #13. Some of the alternatives are completable with a single clue too (but outside of the fixed by game pattern), like sol#1 with additional clue "3" which covers all UA.

205 — extra puzzles from champagne

Postby Pat » Wed Apr 24, 2013 12:40 pm


    champagne has very kindly provided
    a large bag of extra puzzles

    and i have made it my task to review them
    with the hope of finding "interesting" puzzles


    for my first post, i chose
    1.......2.3.4..5....2....6..5.31.......7.8..4....95....7....4....6....8.9...2...6 # champagne # 205 # (36210) #
    — it only needs "basic" moves
    but has an oddity, i'm not saying what (not to spoil it for you)

    my 2nd post —
    1.......2.2.3..4....5....1..4.67.......8.5..9....91....3....8....8....4.9...5...1 # champagne # 205 # (226263) #
    — is tougher, requires "advanced" moves

    all are 5.4-or-lower,
    should be fine for human solvers
