1. Basic Rules

• Each player holds five dice, which are cubic and have six faces numbered ①②③④⑤⑥ respectively.
• When not in a "pure" (zhai) state, ① can represent any of the other numbers ②③④⑤⑥.
• Players take turns to judge whether the previous player's call about the number of a certain dice across all players is correct. If deemed incorrect, one can choose to "open" the call. For example, if the previous player calls six ③s, you must determine if the total number of ③s across all dice is six or more. If you believe it's not, or if you find the claim unreliable, you can "open," and if there are indeed six ③s or more, they win; otherwise, you win.

2. Calling Rules

• Before the game starts, the minimum starting call is agreed upon, categorized into three types: the number of ①s, the count excluding ① (zhai), and the total count of ① plus other numbers (non-zhai).
  • For a 4-player game: The minimum calls are four ①s, five for zhai, and six for non-zhai.
  • For an 8-player game: The minimum calls are eight ①s, nine for zhai, and ten for non-zhai.
• Assuming a 4-player game, the default consensus is 4, 5, 6 | "four ones, five zhai, six to start."
• The first round starts with one player making a call, for example: four ①s, five ②s zhai, or six ②s non-zhai.
• The next player can:
  1. Agree with the previous call and:
     1. "Add one," i.e., X+1 of Y
     2. Not follow the previous call and call X of Z (Z > Y) / X+1 of k (k being any from ② to ⑥)
  2. Change the previous call to zhai, with the count being X of Y but without restriction on Y.
  3. Choose to "open" if disagreeing with the previous player's count.
  4. "Bounce back" by adding two on top of the previous call, i.e., X+2 of Y back to the previous caller.

Specific Scenarios Illustrated:

• If the previous player calls six ③s, the next can call six ④/⑤/⑥, or seven of any from ② to ⑥, or revert to calling six of any including ① as zhai.
• When the previous call is zhai, you can add three to "break zhai," for example, from six ③s zhai to calling nine of any from ② to ⑥ as non-zhai.

3. Terminology Explained

• Sequential dice: Need to reroll as there are no identical dice.
  • ①②③④⑤ ｜②③④⑤⑥
• Surrounding dice plus one/two: When all dice show the same number, it counts as one or two higher.
  • With ①s, it counts as X+1, and if all dice show the same number, it's X+2.
  • Example: ①①③③③ counts as six ③s | ⑥⑥⑥⑥⑥ counts as six ⑥s.
• Adding one: Build on the previous call by adding one more, i.e., X+1 of Y.
• Breaking zhai: For a zhai call, adding three changes it to a non-zhai.
• Opening: The next player opens the previous player's call to determine the win/loss.
• Bounce back: Add two on top of the previous call and give it back to the previous player.
