Boy Howdy's Expert Sudoku has four tricky types of Sudokus to try:

• X Sudoku is the same as regular 9x9 sudoku, but both diagonals must contain 1 to 9 once only.
• Hyper Sudoku is 9x9 but with an additional set of four 3x3 blocks that must contain 1 to 9 once only.
• Jigsaw Sudoku is 9x9 but instead of 3x3 smaller blocks, the blocks are shaped like jigsaw pieces.
• Samurai Sudoku (iPad only, because it's HUGE!) is a super combo of five regular 9x9 sudoku puzzles, overlapping on one corner of one of the 3x3 blocks. Note that the normal row/column constraints are only within each 9x9 square.

• There are 40,000 Sudokus for each of the four types! (10,000 Easy, 10,000 Medium, 10,000 Hard, and 10,000 Evil Sudokus)
