Not an hour after I made my previous post, Sheldonista Jesse S. pulled out a big win. Not only did he find the correct name ("Tunge!" I never would've guessed that spelling!) he found the full rules on a UK site. Check it out!

Jesse, I can't thank you enough. We've literally been looking for this game for years. Years!

I can't wait to bust out a deck and give it a whirl again. And if any other Sheldonistas enjoy a card game from time to time, try it out and let me know how it goes. And don't let the rules deter you (...looking them over, they kinda read like a NASA training manual). Trust me: This is a genuinely awesome game. Give it a try!
