I'm in the Coinut campaign now.
You guys realy run a cool game, I think everyone should give it a go!
Maybe you should make a double or nothing one ( | 2x | 0 | 2x | 0 | 2x | 0 | 2x | 0 | 2x | 0 | 2x | 0 | 2x | 0 | )
Cheers
Actually, Lucky Bit has a "Make Your Own Game" promotion running in another thread:
https://bitcointalk.org/index.php?topic=873587 - if your line gets selected, you can win 2% of the profits it generates (I haven't followed that thread very closely, but I don't think anyone has made a suggestion similar to yours yet).
EDIT: Oh, it seems the multipliers must always be above 0.2, so that wouldn't work.
