i didn't quite get the ranges mechanic. does it mean how far the guess is from the target? it looks like always betting on 3 will win everything that's not hard.
it also got me thinking about the street origins of the craps. i think that dice-light systems are ok for streets and public spaces if executed well. my group actually tried Cairn on the go, but it required a little too much dice. Did anyone tried EZD6 on the go yet?
