Liar’s Dice is a popular bluffing dice game widely played in bars and social gatherings across China, Singapore, Malaysia, and other Asian regions. During the game, both sides roll their dice and keep them hidden, then make declarations based on the visible dice faces. Players rely on probability and psychological judgment to decide whether the opponent is telling the truth or bluffing.

2UP’s Original version simplifies the traditional gameplay into a Player vs Dealer duel, where each round is generated through the Provably Fair system — ensuring randomness that is transparent and verifiable.

Gameplay

Dice values (1–6) are used only for counting quantities.
There is no comparison of size, and no special combinations such as pairs or straights.

The outcome depends on whether the total number of dice showing the declared face value (including both your five dice and the dealer’s five dice) meets or exceeds the quantity you declared.

The game includes two counting modes:

Wildcard (Default)

A dice face value of one counts as a wildcard and can be included as any chosen face value.

No Wildcard

Face value 1 counts only as itself, and cannot be used as a wildcard.

Special Rule

If you declare the dice face value one, the round will automatically switch to No Wildcard mode.

Declaration Rules

You may only declare a quantity that is 1 to 5 higher than the number of that face value you currently hold.

Example:
If you have ”2“ fives, you may declare “3 to 7” fives.

Round Flow

After placing your bet:

You and the dealer each roll five dice.
You can only see your own dice.
Choose a dice face value (1–6).
Choose a quantity (1 to 5).
Select Wildcard (default) / No Wildcard mode.
Submit your selection.

The system then reveals the dealer’s dice and counts the total number of the declared face value according to the chosen mode.

If the total count is equal to or greater than your selection quantity, you win.
Otherwise, the declaration is considered a bluff, and you lose the round.
