Metro puzzle (August 2017) - Moderate

Postby 999_Springs » Tue Sep 18, 2018 7:34 pm

for those not living in the uk, the metro is a free trashy tabloid newspaper filled with celeb gossip and mindless chit chat, designed for casual light reading on buses and the underground, to be silently discarded upon reaching your destination and left behind for the next person who sits down in your filthy seat. their best bit is their weekly mcdonalds vouchers that give you a big mac and fries for £1.99. they've published sudokus since 2005, and now publish an easy, moderate and tough puzzle every weekday. here's a puzzle that a friend of mine sent me, dating back from a year ago or so, which was rated a "moderate" on their difficulty scale:
Code: Select all
.4.|3.5|.9.
2..|8.4|..5
...|.6.|3..
---+---+---
83.|...|.46
..7|...|5..
96.|...|.78
---+---+---
..9|.8.|4..
3..|4.6|..7
.7.|9.1|.8.

because this is only a "moderate" difficulty level puzzle, not to mention found in a trashy newspaper, it shouldn't be any trouble for any of you. the "tough" puzzle from that day was an all singles, and if you trust their difficulty ratings (why wouldn't you?) this ought to definitely be easier than that. so i'm sure you certainly won't need aic's or fish to solve this puzzle. nope, none at all. no really i mean it. what, you think i'm lying? i find your lack of faith disturbing.
Once upon a time I was a teenager who was active on here 2007-2011
ocean and eleven should have paired up to make a sudoku-solving duo called Ocean's Eleven
