The dreidel game is played (
rules) like in the put-and-take game with finger tops (teetotums). The four faces should be: nothing, put one, take half, take all. But this dreidel has all the faces with the same character, gimel, that means
take all: you always win!
But there are other "trick" teetotums that are more subtle. This one currently on ebay:
can be secretly set to be loaded on any of the colors. I have a similar one with the numbers 1 to 6.
Now, how would a real (string) tricking dreidel look? Perhaps by having the upper stem to be a tip it could be accomplished.
