Dear Springbok Puzzler: Thank you for attempting to solve Rubik’s™ Royal Brain Teaser. You’ve taken on a great challenge; we admire your sense of adventure. Yet if you still haven’t solved the puzzle, here are some basic features you’ll need to know about. There are two overlapping sequences of gems that repeat throughout the puzzle, one of color and one of shape. Color sequence: 3 yellow – 2 blue – 1 red – 3 yellow – 2 blue – 1 red, etc. Shape sequence: 3 rectangular – 2 oval – 1 rectangular – 3 oval – 2 rectangular – 1 oval, etc. To make this royal challenge even more curious, Mr. Rubik randomly scattered 20 clear “reversing gems” throughout the chain, which are either oval or rectangular in shape. When the clear oval gem appears, the shape sequence reverses, and when the clear rectangular gem appears, the color sequence reverses (as if mirroring itself). Clear oval: oval – rectangular – rectangular – clear oval – rectangular – rectangular – oval, etc. Clear rectangular: yellow – yellow – yellow – clear rectangular – yellow – yellow – yellow, etc. (Note: There are a few circumstances where “reversing gems” follow each other. When they are of the same shape they cancel each other out.) You may also refer to the box top for additional hints. The sporadic placement of colored gems is accurate. You can use these as reference points to figure out the sequences. The logic challenge created by Erno Rubik is even further enhanced by the fact that the majority of puzzle pieces look identical in shape. However, there are slight variations. Yet like all Springbok puzzles, the right piece fits perfectly. Thanks again for buying Springbok and good luck! Your Springbok puzzle designer p.s.
