I have a suggestion to simplify your code. You could go with this form for slot numbers:

slots = ['one', 'two', 'three', 'four']
slots.each_with_index do |slot, i|
  ...
end

@computer045 thanks, updated it!

Also you could use those values instead of your constants above:

args.grid.w # Always equals 1280
args.grid.h # Always equals 720

It's in the DragonRuby documentation.

@computer045 thanks again, just updated with that change. Much cleaner!
