Sudoku OneTouch

SUDOKU ONE TOUCH doesn’t change a thing about the classic number puzzle game that millions of people know and love. It offers a nearly infinite supply of classic nine-by-nine grids sorted into five difficulty levels. It also keeps time, provides ongoing statistics, and allows players to choose whether the computer should check errors in real time.

However, it differentiates itself from the competition in one key way: Interface. Every action in the game requires just a single, simple swipe. Simply hold your finger on the cell in which you want to enter a number and swipe your finger toward the digit you wish to enter. Entering notes for potential answers requires the same movement, finishing with a downward motion. Benefits of this interface come both in speed -- it’s very quick -- and ergonomics (swiping is much less stressful on one’s hand than repetitively tapping the screen). Fans of this traditional Japanese number game will be in heaven.
