You did it great, did you announce it before you start this promotion or it is like a surprise giveaway? Means that players got it without knowing it earlier that they will get the t-shirt from playing one of your game (plinko)?
It was previously announced by Noah on October 16 by saying that they
have perfected the merchandise.
Then he said he would send out these shirts for free by dropping 50k Plinko balls by November 1 with a $0.01 bet.
But I see no announcement from @shufflecom twitter and this twitter account only retweeted Noah's tweet.
Maybe only a few know about this promotion.
