I know what you mean about the students take a while to get into the game. Hmmm... I wonder if maturity level feeds into that. If you play with high school or college students it might work better. Unfortunately, it looks like the 2003 Japanese published version is out of print! It provided good scaffolding and Japanese cultural references for my students. You can keep checking with beverly enterprises though for a future reprint.

I think this game is about persuading, not arguing. Although it IS fun if you get argumentative players playing it. Even in English, though, being quiet so as to not reveal which card is yours occasionally is a good strategy.
I wonder how we might adjust the game to add more gamelike motivation so that students will produce more spoken English while playing.
How about this idea? Bring a bunch of chips (bingo, transparent, beads, whatever) and put them in a box/cup.
OPTIONAL RULE #1 A student who wins a green card gets three chips.
OPTIONAL RULE #2 Each round, if any student speaks at least one complete sentence to support one of the cards on the table, the judge must give one and (only one) chip to that student. This way, each student who is not the judge can get one chip just for speaking.
OPTIONAL RULE #3 If one of the non-judge students speaks two or more sentences, **and the judge is impressed by what they say**, the judge MAY give a maximum of a second chip to that student.
OPTIONAL RULE #4 Play the game for chips, not just for green cards. The first student to get 15 chipos is the winner. (Could make it more or less chips to make a longer / shorter game)
What do you think? This would encourage students to say **something** about one of the cards on the table - remember it doesn't have to be their own card if they're trying to fool the judge!
