The TipTop scoring formula has several variables. The first, and most common, being the number of pieces cleared in your set:
Set Size = Points Awarded
3 = 150
4 = 250
5 = 500
6 = 750
+7 = 1000
After your set is determined, the scoring is adjusted per set cleared. For example, clearing a set of 3 earns you 150 points. Now let’s say that move results in a chain reaction that clears another set of 4 - this would award you 500 points (250 for the set of 4, times 2 for the chain reaction), plus the original 150 points. Each chain reaction adjusts the number multiplier up by one. In other words, the 2nd set cleared in a chain reaction is multiplied by two; the third set cleared in a chain reaction is multiplied by three, etc.
