Ciphers

Spiral off the pad

Easy–medium. Route cipher. Fill a 3×4 grid row-major, read clockwise from the outside in.

First-night quiz

Five short questions on the 30 August edition. No trick items. Answers under the break.

Binary on the desk

Five ASCII bytes, a three-rail fence, and a one-line quiz about the first edition.

The keyword is stainless

A keyword cipher built on STAINLESS, plus hex that names the unglamorous miracle.

Eight in the yard

A letter matrix of catch, stack, train, and the quiet jobs around them.

Catch, then the ship

A Caesar five, Morse from the pad, and a tiny A-is-1 reflight.

The night sky is a schedule

A substitution cryptogram and a ROT13 of the same Gulf idea. Two cribs, then the lights.

The alphabet, reversed

Atbash, a rails cross, a power matrix, and a hex coalition.
