Mummy, Dino, and Mandala Mazes

Creative expression, learning, and focusing are some of the most important activities which children should be encouraged to do from an early age. Driven by this idea, Elizabeth Carpenter has published several oversized books, which give kids the opportunity to solve beautifully drawn line mazes, color them, and learn interesting trivia all at once. The Mummy Mazes Monumental Book contains 28 poster-size mazes based on Ancient Egypt themes, along with explanations about each of the included objects. The Dino Mazes Colossal Fossil Book contains 31 poster-size mazes, depicting various dinosaurs, accompanied by descriptions and quick facts about them. Recently, Elizabeth also published a Mandala Mazes book, which can be popular among older people looking for fun, relaxing activities as well. In terms of difficulty, the Dino and the Mummy mazes seem to fall on the easier side, while the Mandala mazes are a bit more challenging. After being completed, the mazes can be detached and used as posters, even though we think they look best organized together. All three books offer great quality and we would highly recommend them to any maze enthusiast.

Knight and Coins

Bob and Jane are taking turns, placing knights and coins respectively on a chessboard. If Bob is allowed to place a knight only on an empty square which is not attacked by another knight, how many pieces at most can he place before running out of moves? Assume that Jane starts second and plays optimally, trying to prevent Bob from placing knights on the board.

Bob can place at most 16 knights. One way to do this is to keep placing knights only on the 32 white squares. In order to see that Jane can prevent Bob from placing more than 16 knights, split the board in four 4x4 grids. Then, group the squares in each grid in pairs, as shown on the image below. If Bob places a knight on any square, then Jane will place a coin on its paired square. This way Bob can place at most one knight on each of the four red squares, one knight on each of the four green squares, one knight on each of the four brown squares, and one knight on each of the four blue squares. Therefore, he can not place more than 64/4 = 16 knights on the board.
