Su Doku Live

Su Doku Live is a sodoku competitive game that includes sprint races, with up to 32 players peeking at each other games, while rushing to solve the puzzle.

Looking at the opponents board does help, but it's also a distraction no one can afford.
Mature players enjoy cooperative games. No guessing should be involved in Sudoku, so chat, ask players the deduction techniques, share notes and become a better player.
Not connected while flying somewhere? No problem! Sudoku Live saves you friends best times to give you something to look for in single player games. Play against the clock and share your records.
Besides the usual "solver", the unlimited puzzle generator, Su Doku live also has some less comon features like full networking support, drag n drop of puzzles, player hints with visual explanation of the solving techniques and much more.
