Spheroku - color sudoku on a sphere - brain puzzle
by: Pawel Bodytko • 115
Spheroku is sudoku. It has the same logic, the same rules, the same addictive qualities. But Spheroku feels different. It is more dynamic & active. Plus, it does not look like you need a math degree to solve a puzzle. Just use your brain. It is all about logic and observation.
Replace the gray tiles on the sphere with 9 colors, so that every vertical slice, every horizontal slice, and 3 x 3 are surrounded by dark line contains only 1 of each color. Each level contains 100 games.
About the Difficulty Levels:
• Beginner and Advanced levels always have at least one cell where you can place the color. You just need to find them. (Expert player game time: 3 to 10 minutes to solve each level)
• Expert level might require using color dots to mark alternatives and to determine which color that can be placed in each cell. (10-20 minutes)
• Master level will need a bit more of your brain power... You will probably have to play different scenarios using markers -- Two dots of the same color on the same cell is a good place where to start a scenario... (15 min-1.5 hr).
