Frog-In-A-WellTM is a form of Round Sudoku. Traditional Round Sudoku usually has 5 rings and involves 10 numbers. Frog-In-A-WellTM is for younger players and contains only 4 rings and involves 8 numbers. Because it has a different structure than traditional Round Sudoku, this puzzle has more exposed numbers, but a bit more concentration is required to solve it.

Rules: Each ring (there are 4) must contain 8 numbers from 1 to 8. Each wedge of the well (there are 8) plus its opposite wedge must also contain 8 numbers from 1 to 8. It takes 5 to 10 minutes to solve.
