Pyramid Sudoku reinvents the classic puzzle with a nested twist you have never seen before. THE PYRAMID Every grid is a real sudoku hiding inside a bigger one. Solve a small puzzle and it reveals a single number in the grid above it. Fill an entire grid to unlock the next level of the pyramid. Go 2, 3, or 4 levels deep — the deeper you go, the greater the challenge. GUESS AND DEDUCE On the larger grids you can place your own guesses. But be careful: the game will not tell you if a guess is wrong. You will only find out when you complete the grid or solve the puzzle beneath it. Just like real sudoku — think before you commit. CLASSIC MODE, FOUR WAYS Prefer a traditional game? Play Easy, Normal, Hard, or Extreme. Extreme adds a 15-second move timer and three lives for true masters.
