Your goal is to steal the ill-gotten treasures from the pirates. They are hidden on nine islands and are guarded by ferocious, merciless pirates. Watch the demo first to see how it is done. You start from island 1 and progress towards island 10. Each island is guarded tighter than the one before.

Many have ventured, very few have returned alive, and rich. Most became skeletons piled up on the islands or became shark bait. Are you brave enough and smart enough to steal all 10 treasure chests from the pirates?

This puzzle is an adaptation of a famous ancient Chinese puzzle. The highest level, level 10, is so difficult it has been researched by well-known mathematicians. The shortest known solution is 81 steps, found in 1964 and published in Scientific America. You will have fame if you can find a better solution to Level 10, but you have to reach there first, can you?
