Welcome to Crossnumbers Quarterly
A puzzle world where digits and numbers rule as opposed to letters and words.
The puzzles are of the type seen in The Listener Crossword and The Magpie.
Whoops again! In Which Clue by Zag the clue for 1dn should read has the same number of factors as 4dn and 5dn. Once again sincere apologies for this oversight.
Whoops. In Diagonal Primes in CQ8 the clue for 1ac should read The smallest prime in the grid and sum of the digits of 6dn. Apologies.
CQ8 was emailed to all subscribers on Thursday 27th September 2018.
Prize puzzle - The Fisher Maze by Zag
As of today, 14th Sept, we have received 4 entries. Climbing slowly but surely!
There's just about a week left to get your entry in and a chance to win a copy of the book or a free sub for 2019.
CQ7 was emailed to all subscribers on Thursday 28th June 2018.
CQ5 Errata.
Find the Intruder by Zag : 18dn should read 16dn + 17dn
Unbelievably It's Real by Encota : 7ac should read factor of E
Buzzard Point III by Zag : 1ac should read friendly, multiple of the digit sum of 12dn. Also in the preamble hole 12 should be 2dn and not 3dn as stated.
Apologies for those typos.
CQ5 was emailed to all subscribers who have renewed their subscription for 2018 on Thursday 28th Dec 2017. It's never too late to renew!!
Check out the puzzles section for the odd little extra.
CQ4 Clarification
It has been pointed out that the preamble instruction in Whodunnit? by Moog is imprecise. The statement 'Factors and multiples are non-trivial' does NOT apply to 16ac.
The clue for 16ac should read
'The population of the village which has 20 factors including 1 and itself'
Apologies for this oversight and the frustration that it has caused. We hope it hasn't detracted from your enjoyment of the puzzle.
It should be noted that in Pandigital Products by Oyler the clues for 13dn and 18dn should read
13dn it has 6 factors including 1 and itself.
18dn it has 10 factors including 1 and itself.
The launch issue is free and is still available to anyone interested.
