For this series of four A5 spiral-bound puzzle books, I created a bold theme of colours that create a distinctive identity in the series whilst keeping each book unique. Each book, Wordsearch, Crossword, Sudoku, and Brain Training, features its own vibrant palette while maintaining consistent geometric motifs and strong typographic hierarchy to ensure instant recognisability as a set. The covers use stacked block patterns and chunky letterforms to evoke a playful, retro-gaming feel, while the interior layouts are clean, clear, and easy to navigate. The result is a cohesive puzzle series suitable for all ages.
