A little FYI here...
9 times out of 10, if you click like crazy on the groups in the lower right corner you can get up to level 4 or 5 in about a minute.

Those early levels aren't worth many points so getting up to the higher levels as quickly as possible will save you the time of trying to grab the big groups (and larger points) at those lower levels and risk an early end to your run up the high score lists.
Once you get to above the 4th and 5th levels, then those points really start to add up.
Well, at least that how Sara and I have been doing it.
