While the speed bonus is the MUST to do it, to do those you need 5 matches.
Five matches are very easy to do. As for the fact that many of you jsut do 3 matches, do them in multi matches, so say bye bye to them unless it is a MUST since you can't do anything else
First, get the screen up to 5 rows. Then search for anything that will give you a five. If only the bottom 4 rows have a match and another one of those blocks is coming, wait for it. Then match. Again, you need to remove as many blocks as possible to improve your score.
So pictures are coming soon!
