Ra! Ra! Ra!

Ra rocks. I especially like the scenario the OP lays out, where one or two players have a shot at filling up the draft with tiles after everyone else has bid out, hoping no sun tiles appear. It's like that old game show Press Your Luck.

"Come on, big bucks, NO WHAMMIES".

Sometimes you get the big bucks, sometimes you get the Whammy.

I have yet to figure out the correct strategy, but nothing beats a group chanting "RA, RA, RA" hoping the last player craps out. Even when I come in dead last, almost always the case, I still have a ton of fun playing.
