Take a break. Find your next move. Enjoy the satisfaction of solving Sudoku.
Sudoku: Infinite Classic brings a fresh, modern design to the classic number puzzle, and new ways to play it: race a friend live, scan a puzzle from paper, play a chain of linked boards, and see which techniques every puzzle took.
RACE YOUR FRIEND LIVE
• Duels: you both solve the same puzzle, and live progress bars show how far each of you is.
• Finished first? Your friend races your ghost: how far you were at the same moment of your solve.
• Join a public duel, or challenge a friend with a code.
• Friend Leagues: share a code with family, friends or the office. Everyone's daily challenge scores add up over the week, and a new table starts every Monday.
SCAN A PUZZLE FROM PAPER
Photograph a Sudoku in a newspaper or book, check the digits, and play it here with hints and error checking. The grid is read on your device; the photo never leaves it.
INFINITE CHAIN
One puzzle that keeps going: finish a board and its corner box starts the next one. Three mistakes end the chain. How far can you go?
KNOW WHAT IT TOOK
Every win names the techniques the puzzle needed, hardest first.
LEARN YOUR NEXT MOVE
