The word "Kugelach" comes from the word "Kugel" {or ball} which is a Jewish food, a type of thing that Jews {we} usually eat on Saturday, its made out of eggs and either potatos {potato kugel} or luksihin {spaggetti - Lukshin Kugel} or even with cooked vegetables and spaggeti {Yerushalmi Kugel} and more... So the meaning of "Kugelach" is - it is a game, similer to Jacks, that you have 5 of these dices {kugs - which are in the shape and similer color of kugel}, and you toss one up and you pick up 1 until the set is done... then you have twosies threesies foursies and then sweep, then bridgies then Al Yad {on the hand} then Pach Koifel {double smack} and so on.... You can buy Kugelach at practicaly every Jewish store! and also at "JET"inc. {Jewish Educational Toys}. Prices range from $1.00 to $4.00 for a five set {some also come with a pouch}. Kugelach is the most popular Jewish game. You will find kids playing with Kugelach at every Jewish school.
To answer your question in simple {not recommended} - its a Jewish game.
