A bumper collection of 300 quick crossword puzzles to test your word knowledge and have you reaching for the thesaurus. For those who find standard Sudoku a doddle and the 9x9 grid doesn't offer enough of a challenge, then why not graduate to these big and beautiful 3D style grids? For fans of the great Sir Arthur Conan Doyle detective series comes a collection of puzzles inspired by Holmes' most popular cases and adventures. The puzzles solve as standard dot to dots except that they contains various places where you need to take your pencil off the page and start again from the next dot - this happens when you encounter a white (hollow) dot. By solving puzzles regularly, your brain will stay engaged and active helping you to remain sharp and focussed.

This makes it a great book for anyone who enjoys tackling a range of different Sudoku-style puzzles! Printed in a highly portable format which can be taken on your travels or sit neatly on your bedside table. Read each section to brush up on a particular part of the body, and test how much you learned with crosswords, anagrams, missing letter puzzles, secret codes and more. These puzzles function like standard codewords, however the words you need to enter in the grid wrap around the three visible faces of a 3D cube. And there are lots of custom-drawn images of animals to accompany the facts that children can enjoy colouring in to bring the book to life.With mosaic puzzles, you are given numbered clues inside the grid and must work out from these which of the neighbouring squares are filled, again to enable you to determine whether every square in the grid should be shaded or not. Group sum Sudoku is a great variant of the standard Sudoku puzzle that introduces a mathematical element to the solving process. The book comes with not only answers, but (for some of them) explanations of how to tackle similar problems to point you along your way. All solutions are included at the back of this book - we hope you'll enjoy solving the puzzles in this collection.

Education is a key part of the development of a young witch, wizard or warlock and this book is full of puzzles that will help stretch your mind and test your mettle. If you're missing the time you spent in your garden in the summer months, this quiz and puzzle book may be the one for you. Do you miss the days before sat-navs, when you could navigate the length of the country with just a paper road map? With over 400 puzzles, including logic puzzles, riddles, lateral-thinking and pattern-solving, you'll be tested in every area. So if you are a fan of anagram puzzles or know someone else who is, this book could be right up your street!

There may be - particularly at the start of the puzzle - multiple places in the grid where a word can be placed. The more codewords you solve the more you get a sense for common patterns that occur, for instance the most common double-letters and so forth, which can be very useful when you see the same number occur in consecutive squares in the grid. As such the grids and clues are large and clear, so whilst the puzzles might be a little tricky from time to time, reading the clues and using the grids won't be!
