Primary — KS2 (Years 3–6) — Easy (3-letter) and Medium (4-letter) puzzles support vocabulary, spelling patterns and word recognition. Ideal as a starter, early-finisher task, or homework. Pairs with the English National Curriculum's word-reading and spelling strands.

Secondary — KS3 & KS4 (Years 7–11) — Hard (5-letter) puzzles extend vocabulary range, develop orthographic fluency, and reinforce morphological awareness. Useful as a warm-up for English lessons, a retrieval activity, or GCSE-level revision for etymology and word-building. Form tutors can run the daily puzzle in registration as a whole-class challenge.

SEN & intervention groups — The single-letter-change structure makes phonological differences visible, which supports dyslexic and SpLD learners. Practice mode lets you run as many puzzles as needed at a consistent difficulty.
