Crack codes: three practical starting methods

A secret code does not have to be complicated. It may depend on order, a symbol or a simple shift. The useful skill is working systematically.

Logic games do not require advanced mathematics. Often you only need to spot differences, arrange information and test a rule one step at a time.

Three practical tips

1. Write every known symbol down in the order shown.
2. Check whether numbers relate to letters, locations or positions.
3. Reject a rule if it conflicts with a clue you can actually see.

Code Breaker is a free introduction. Code Workshop 25 uses codes within a longer game.
