How do I match a group of connecting blocks

Hi

I'm wondering how to do a check to see if a group of the same items are connected. Like this:

I want the blue ones to be destroyed. I have looked at some match3 tutorials, but they don't do grouping like this, and they are insanely complicated. If possible, I need it to be as lightweight as possible, it's for the Wii U.

I guess by using plugins and this is about as simple as it gets:

Match 2, incredibly easy. Match 3, yeah that's going to require some logic.

Basically it's done by looping over all the pieces and flood filling to the other pieces of the same color. Use a variable to label each group and to make the pieces that were processed already.

The only optimization is to use an array to do a piece lookup instead of picking by collision or general picking.

Here's an example to peruse:

Oooooo nice

Thanks!

I have tried to analyze you example the best I can, but I just cannot get it to work with anything, nor how to modify it to suit my needs. Here's the capx I'm using - https://www.dropbox.com/s/t2yce9669c21g ... .capx?dl=0

I need the matching to happen once the icons have stopped falling, if there's at least three or more in group. I'd be forever grafeful for any assistance.

Here is an example that matches clusters of 3 or more pieces and then applies gravity.

The Matching bit is based on an example posted by ROJOhound (flood fill) but I don't have a link to the original.

This looks like it should work, thanks!

FloodFill, how it works a bit explained.
