It's flexible, portable, can be played anywhere any time, and doesn't need batteries. With its addictive and broad-ranging appeal, Australian puzzle invention The Kaleidoscope Classic is set to be on everyone's minds and wish lists this Christmas. Based on the traditional checkerboard it looks deceptively simple.

The challenge of the puzzle is to fit 18 unique, four-coloured pieces into a square frame in various patterns and designs, ranging in difficulty from very easy to exceptionally hard. Offering one new challenge each week for the next 100 years, the lifetime supply makes it the challenge that everyone can solve but no one can conquer. From children as young as six to students, puzzle and game enthusiasts, executives and professionals, corporate organizations and retirees, players can create everything from animals to space craft, flowers to sports and science to abstract art. The Kaleidoscope Classic has already been dubbed the new Rubik's Cube, however Australian inventor and psychologist Dr. Mark Wood said it had the potential to become a much bigger social phenomenon with its many dimensions creating a fun challenge for everyone. "Everyone on the family can play" he said. "What makes it extremely addictive is the joy and sense of achievement you experience when you complete each of the many challenges". "In comparison the Rubik's Cube only had one challenge".

Once you've tried The Kaleidoscope Classic, you'll be booked for life. Without a doubt, it pushes the boundaries of your creativity, intelligence and thinking powers. Dr. Wood and the game was also great for self-esteem, as various challenges were met more effectively as your skill developed, and as a useful aid to help concentration. "It's the game that actually responds to your thinking", he said. Players can also become part of an online community where they can share their solutions, play online, create their own personal gallery and won prizes. The new revolution in puzzles is already starting to sweep Australia with more than 200 outlets selling the game. Dr Wood said it was expected that one in three households in Australia would eventually own The Kaleidoscope Classic, with many likely to be found under the Christmas tree this year.

Ranging from $ 24.95 to $ 59.95 the game is available from Myer and leading toy, game and puzzle stores nationwide. The Kaleidoscope Classic is tipped to be the best-seller puzzle this year.
