<<< About "Dice" >>>
Dice is a sample program for "DICE" class dialog control.
The program tryies to simulate a gambling game, Cee-lo (so-called "Chinchirorin" in Japan. Hereinafter, descripsions are based on Japanese "Chinchirorin".)
"Chinchirorin" is played between a dealer and a player. A game starts by a dealer throwing three dices. The dealer may immediately win (without players competing)  or lose, because of "hands" or "Point" (See below). After the dealer's dice throw, a player is eligible to compete only when he or she rolls three dices and makes "Point" (the number of the third dice, with the other two dices having the same number) or any of "hands".
A dealer loses, when a player has Storm (triple of the same number) or 456, even though the dealer made Point. Otherwise, a dealer and a player compete by the number of the third dice.

Synopses of Hands or twins follow.
<Your hand> - Gain - Description
Point - the bet amount - In case that the third dice number is 6, the dealer immediately wins and in case of 1, he or she immediately loses. Otherwise, the dealer wins, when he or she gets a bigger number of the third dice than players'.
Storm - 3 times the bet - A dealer or players immediately wins, when the same three numbers come out.
456 (four-five-six) - 2 times the bet - A game is immediately won, when 4, 5 and 6 come out.
123 (one-two-three) - 2 times the bet - A game is immediately lost, when 1, 2 and 3 come out.
