Sudoku 2

By Finger Arts released on: 2010-05-07T07:55:16Z

Sudoku 2 is Sudoku + Point System, Runs, and Online Leaderboards. Discover the next evolution of Sudoku with amazing graphics, animations, and ease of use. This is a Sudoku like one you have never experienced before ;)
To the classic Sudoku, we added:

=> A smart point system, wherein your score is based on 1) the value of each number multiplied (at the time of its match) by a multiplier that decreases in time and 2) the value of each block, row, column multiplied (at the time of its completion) by the decreasing multiplier

=> Thanks to OpenFeint, you can now rank and compare Sudoku scores and achievements against friends and strangers

=> Sudoku 2 also counts the runs, that is, each uninterrupted sequence of games won, and adds them to the online leaderboards
In Sudoku 2, you win a game when you solve a puzzle with 3 errors or less (we used this threshold to give a bit of slack for mis-tapping :) Also, you have a number of hints to help you play (more at the easy, less at the hard level). To fit any taste, you can choose between a lush tile look or a more classic board look :)
You gain access to medium level after you win the easy level 2 times consecutively, same for hard level (3 times)
And remember, as always, your five stars (★★★★★) are very important to us, and they help us to bring you free updates and new exciting games!
