Raja, also known by his full name A. Rajathilagam, is pleased to unveil the launch of Cross Number Puzzle (Book 1)—the inaugural release in a new series designed to captivate number puzzle fans. Featuring a thoughtfully crafted collection of fifty puzzles, the book ranges from straightforward sums to intricate logic grids, offering mental stimulation for solvers of all ages.
Diverging from conventional word-based puzzles, this book is built entirely around numbers and logic. Each puzzle invites the reader to fill in digits so that every defined shape within the grid reaches a specific total. The initial puzzles employ simple addition techniques, making them ideal for children, families, and educators introducing numeracy in an enjoyable format. As readers progress, the complexity increases—demanding foresight, multi-directional reasoning, and patience.
Raja’s passion for numerical patterns began early, sparked during his school years through a fascination with magic squares and mental arithmetic. He recalls experimenting with numbers long before modern tools like calculators and smartphones were widely available. This lifelong interest in structured number play inspired him to design puzzles that are both mentally challenging and visually intriguing. The book includes puzzles shaped like animals and geometric figures, drawing solvers in to explore and complete each challenge with care and determination.
Each grid includes a full solution, helping to prevent solver frustration and encouraging learning by example. Beyond recreational use, Cross Number Puzzle (Book 1) is a valuable asset for publishers seeking quality logic content. Its universal, language-neutral format allows for easy integration into international publications. Editors can license individual puzzles or the full collection to enrich reader experiences with a novel alternative to crosswords or sudoku.
A. Rajathilagam has been creating numerical puzzles for more than thirty years. His deep passion for logical deduction and pattern recognition inspired this unique collection, offering thoughtful challenges that reward persistence and creativity.
