123 Dice - 3-Piece Set Size: 16mm "123 Dice" (Hifumi Dice) are used in the dice game Chinchiro. When you're losing badly and want to use 456 dice, your opponent might know about them, preventing you from using them. These dice are your lifeline in a crisis, designed to bring about a dramatic comeback with a single roll for a winning "Pinzoro" (three ones). The back of the 1 is 1, the back of the 2 is 2, and the back of the 3 is 3. These dice only show 1, 2, or 3. They're essentially a 123 version of the 456 dice. The probability of rolling Pinzoro with normal dice is 1/6 x 1/6 x 1/6 = 1/216. However, with the 123 Dice, it becomes: 2/6 x 2/6 x 2/6 = 1/27 This is an increase of approximately 8 times! The probability of rolling "2-Zoro" (three twos) and "3-Zoro" (three threes) also increases similarly. However, be aware that you can only get a maximum of 3, and the probability of losing hands like "123" also increases. These dice are a double-edged sword, offering a chance for a stunning comeback.
