This game had a much different focus than I expected when I picked it up. Instead of providing challenging puzzles, the sudoku grids range from very easy to middling and you strive to solve them quickly and improve your solving times.
The puzzles that the game provides are much simpler than what you would see in a newspaper, even at the highest difficulty level of the game and near the top of the career mode.
The tools the game provides for helping you solve puzzles are great. It highlights rows, columns and mini-grids as you move around the grid. It gives you a graph of how many of each number have been placed, which is perfect for choosing a starting point in the puzzle. It also lets you place pencil marks and erase them. The video tips in the game clearly explain and demonstrate solving strategies that you might not otherwise understand by reading about.
The controls have just one problem with them: if you hold down a direction, or hold the joystick in a direction, the game doesn't keep scrolling. This means you're in for a strenuous thumb workout if you play for an extended amount of time.
Sudoku Coach is a nice simple game with great tools provided for helping you solve the puzzles. Pick it up at a bargain price and use it for a stocking stuffer. But don't give it to someone who is already quite good at sudoku puzzles, otherwise they may feel insulted.
