Shinydoku

Love sudoku? You’ll love Shinydoku!

Features

Designed especially for the iPhone and iPod touch
Shinydoku is designed exclusively for the iPhone and iPod touch. Large text and buttons and a simple interface makes it easy to play sudoku on the go.
Touch to select, and swipe to “nudge”
Touching a cell selects it. But, not quite the cell you want? Simply swipe your finger across the touch screen to move the selection in the same direction.
Two marking modes

Pencil mode allows you to record possible numbers in a cell, and pen mode sets your answer. Don’t worry, you can easily change your answer by simply selecting another number.

Tip: Pressing the number a second time removes it from the cell. This is really handy to erase a cell. Simply press any number twice in pen mode.

Unlimited undo history
Made a mistake? No big deal! Simply hit the undo button.
Five levels of difficulty
Shinydoku includes five difficulty levels to match your skill level. Anyone from the novice to the most skilled sudoku solver will have fun puzzles to solve.
Fun, symmetric puzzles
Real life loves symmetry, and sudoku does too. Symmetric puzzles are more fun to solve than a purely random puzzle.
Over 70,000 puzzles
Always have a new puzzle to solve. Each puzzle has only a single solution and is solvable exclusively with logic. No guessing required!
