In current implementation number may not begin with 0. Any number can be guessed in less than one minute i.e. 60sec. "Exist" column displays total number of digits you guessed right but they are placed in the wrong position. "Match" shows how many of those that exist were placed at the right positions. Once you have guessed all the numbers correctly, then you will be preceded to the further higher levels.
