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!

I don’t usually leave reviews for apps I dislike, but this one will not allow me to delete from App Library, only from Home Screen. So just beware before downloading it and getting stuck with it.

I enjoy playing many of your games with Sudoku being one of my favorites. However, just in the past few days there seems be a glitch. When I am trying to put my numbers in the boxes, the numbers often will jump to a different (wrong) square which can be quite annoying. It would be great if you would check into this. Thank you for many hours of normally relaxing entertainment!
