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.
Zag has compiled fifteen puzzles that all use a 3x5 grid. These puzzles will be referred to in an article that will appear in Mathematics Today which is an IMA publication. They can be used as practice for the Ritangle competition. You can download the puzzles using the link below.
There's a brief introduction followed by the puzzles, hints, full solutions and lists of useful numbers.
