How exactly is damage calculated for 4 & 5 matches?

Unknown

So say a blue gem does 50 damage with your team.

There are 4 other gems in the row, we'll say 2 yellow and 2 black. Each do 40 damage.

You do a match 4 on that row with blue. The damage doesn't end up as 200 (just the 4) or the entire row (200+160 for 360).

How do the calc's work for this?

The person that makes the row match uses his value for all the color. For example if Magneto does 50 per blue and 5 per red, and Thor does 50 per red and 5 per blue and you match 4 blue and there 4 more red on the side, you get 4X50 + 4X5 = 220. It's subject to cascade so if something else formed a match on top of that match 4 the damage for the match 4 may be reduced. Also if the match 4 forms multiple matches in that row, you get the damage for both matches even though some of the tiles will be counted twice.

Say, that's neat. Thanks for the clarification!
