Sue Doku is the fastest, simplest, most elegant sudoku app for the iPad.

Sue’s unique quick-entry keypad follows your thumbs wherever they are, resulting in lightning fast game play. Gesture support means you can swipe to delete, press to get hints. Light and dark modes let you play indoors or out.

Sue can be easygoing or cruel depending on the level you choose; she’ll keep track of your best and average times. Thousands of beautifully symmetrical games, each solvable using standard sudoku strategies, mean no guessing required.

And, unlike most sudoku apps that are (let’s face it) downright homely, Sue is gorgeous. She sports a radically minimal, aesthetically pleasing design that’s as easy on your eyes as it is on your thumbs.
