Rules
Each player starts with 5 dice
Each player rolls 1 die to decide to goes first, highest wins
Each player then rolls their 5 dice at the same time
Each player looks at their five dice, but does not reveal to other players
On a player's turn, they have one of two choices:
1. Make a claim about the total number of dice in play, for example, "five fours", then pass the turn on the next player
2. Call "liar" on the previous player's claim
The number 1 on a die is considered "wildcard" as a part of the claim
The claim MUST be higher than the previous player's claim (see the chart)
If liar is called, all players reveal their dice and push forward those relevant to the claim
For example, if a previous player claims "five fours" and the player in turn calls "liar", each player reveals their dice and pushes forward all 5 and 1 dice.
The total of the pushed dice is counted
If the previous player's claim is higher than the counted dice, that player loses the round and forfeits the amount of dice by which their claim was false into the discard pile
If the previous player's claim is lower than the counted dice, the player calling "liar" forfeits the amount of dice by which their claim was false into the discard pile
If the previous player's claim is exactly the counted dice, the player calling "liar" forfeits 1 die into the discard pile
The loser of the round goes first on the next round
Once a player has forfeited all dice, they are out and do not participate in future rounds
The last player with one or more dice wins

House rules
The adult version may use a substitute term when calling "liar"
If a player asks, "whose turn is it?" or "is it my turn?", forfeit one die to the discard pile
If a player asks, "how many are left?", forfeit one die to the discard pile (use the discard pile to find how many are left!)
Table talk, fishing and probing are allowed before a player makes a choice, for example, "so you have a lot of fives hey?"

Summary
Roll your 5 dice, have a look, but show nobody else
On your turn, either:
1. make a higher claim than the previous player
2. call the previous player a "liar"
If anyone decides "liar" everyone reveals their dice and pushes forward the relevant dice
Count the dice to decide if you there was a liar
Depending on the count, one player will lose one or more dice
Loser goes first for the next round
The overall winner is the last person with one or more dice

A claim is "higher" by being:
a higher count
the same count with a higher dice value
the higher count and a higher dice value

For example:
"four fives" is higher than "three fives"
"seven threes is higher than seven twos"
"twelve sixes is higher then "eight fours"

The 1 dice value is a wildcard and is included in the claim, except when the claim itself is about 1.
If the claim is for ones, then the count must be more than half of the count in the previous claim to be considered higher.

For example:
"two ones" is higher than "three sixes" because two is more than half of three
"three ones" is higher than "five threes" because three is higher than half of five
"four ones" is higher than "six fours" because four is higher than half of six

See the table over the page for a detailed breakdown of the ordering of a claim.
