ICOSOKU

"IcoSoKu combines the deduction of placement puzzles like Minesweeper or Blackout! with the mathematical puzzling of a magic square or a Sudoku puzzle. And by making the puzzle three-dimensional, it places a healthy demand on your puzzly faculties . . . as soon as you’ve placed the final tile and searched the puzzle ball all over, confirming a successful solution… all you want to do is strip away all of the tiles and pegs to test your wits again."
