The Match engine is the most common name for the algorithm that simulates the matches in Hattrick. Often blamed for unlikely results, the Match engine might just be one of the most cursed features of Hattrick.
Last ME update was performed on 19-03-2010. On the new engine there is no chance in the 45th and the 90th minute (the most chances seem to happen between min. 25-37) and the regular chances distribution was enhanced.
There is an opinion (do not confuse it with a rule) that says that the match engine will consider first the general probability of winning for both teams, after that it will consider the exact score and in the end it will decide the distribution of the chances (which one will be goal and which one not). This would explain somehow how at times a wretched attack rating will score against an utopian defending rating or how a divine attack rating doesn't score against a solid defending rating, for example.
The match engine start calculating the matches exactly when the matches start. It is a wrong common belief that the 20 minute period before matches are the time when the calculations take place, but that period is merely a buffer so that managers submit their line-up in good time. This was stated on the forum by HT-Bjorn in the following post:

|Calculations start at kick-off :o) The 15 mins before match start is like a "time buffer" for different kinds of stuff and so that ppl won't place orders at the same moment matches are about to start, which could mess things up a bit.|
