[help] Creating a game like Festive Fallout!

Hi. I would really like to create a similar game to this one…
http://www.addictinggames.com/festivefallout.html

Does anyone have an idea of how this was created. I’m NOT just looking for someone to give me the whole game. I am willing to create the game myself. But It would be great if someone could point me in the right direction. Like I’m not sure how they make it so that after a column disappears, all the columns shift together. I am really unsure of where to even start with this, but I am really keen to learn anything.
Thanks!:b::thumb:

I have a game that does this kind of thing. I did this by basically creating an array that represented the grid of rows/cols.

So, when objects are removed, you basically just loop through each column backwards, and move blocks down to the lowest available position. If you need help, give me your Yahoo or IM chat screenname and I’ll show you how I did it.

Thanks a million. If I run into any trouble i will definitely contact you. Thanks a million!!
