Welcome to the Fibbing Dice game. This is an implementation of the "Dudo" dice game, that can be played in a group over a video/audio call.

As with many games, explaining the rules can seem pretty complicated. This isn't a difficult game though, so either read the below or pick it up as you go along, assuming you're playing with experienced players.
Every player starts with five dice. The aim of the game is to be the last player with any dice. The game consists of a number of rounds where players can only see their own dice, and take turns to make calls predicting what dice are present.
The full instructions begin below, but if you can also see an example game.
When you join a room that has not got a game playing, you will see all of the current players. Your player has a blue border as shown. The arrow indicates the direction of play.
The host (indicated by the lightning bolt) should wait until all players are present, then press . The host also has the ability to change game settings before the game starts - see the cog, or to remove players at any time by clicking on them.
All players should click the to roll a single dice. The player with the highest value becomes the first player to make a call. If there is a draw, keep rolling until there is a winner. The starter for each round is highlighted in green. Once the starter is decided, click again to receive your dice.
The call (which is made through the video/audio call) should be of the form "four fives", which means "I predict that there are at least four dice on the table that have five spots showing". The next player (indicated by the arrows) has to either make a larger call, or call Dudo ("I doubt").
For the first call, it is not allowed to start with a dice value of one, because ones are special in most cases (explained below). This means the lowest value starting call is "one two".
The player above may wish to consider a call of "threes", or they may decide to bluff about what dice they have.
To make a larger call, the next player has to either increase the quantity of dice to increase the dice value, or even both. If you increase the quantity of dice then it is allowed to decrease the dice value. By making a larger call, the player accepts the call of the previous player, and play moves on to the next player who then either raises the call, or calls Dudo.
The diagram below shows some example possible calls, assuming a first call of "five fours". The first option "five fives" increases the dice value only. The second example, "six fours" increases the dice quantity but leaves the dice value unchanged. The third example, "six twos", increases the dice quantity and takes the opportunity to reduce the dice value. It is perfectly acceptable to make bigger jumps, so a call of "eight sixes" in this case may be bold, but is allowed.
The remaining two options are explained in the sections below.
For most of the game, the dice value of one can be used as a wildcard value which matches with all other dice values. This means that a call of "five fours" actually means all dice values that are either four or one. With 25 dice, you would expect there to be approximately eight of each value from two to six. When making a new call, it is possible to change from using the regular dice values of two to six, to calling "ones" instead. This is shown in the fourth option in the diagram above. When a call with ones is made, the quantity of dice called must be halved and rounded up if necessary. So a call of "four fives" could be followed by a call of "two ones", or a call of "five sixes" could be followed by a call of "three ones".
When a call of ones is made, it is only the dice with ones showing that count.
It is also possible to respond to a call of "ones" by changing back to a call of dice values two to six. To do this, the quantity of dice called must be doubled, plus one. So a call of "two ones" could be followed by a call of "five threes", but not "four threes". A call of "six ones" could be followed by a call of "thirteen twos".
The player starting a round is not allowed to have their first call be "ones".
When the player that is due to make the next call does not believe the previous players call, they should say Dudo, and click on the button. This will result in all dice being shown player by player, starting with the player that called Dudo. Once all dice are shown, the relevant dice values (including ones or not, depending on the call) should be counted up to see whether the call was correct. If the call is correct - there were at least as many dice with the called dice value - then the player who called Dudo lost. If there were not enough dice, the playing making the call lost. After determining which player lost, they should press the button. The losing player has a dice taken away from them
If you press the Loser button when you didn't mean to, don't worry, the Loser button transforms into an which you can use to go back and let the other player press the loser button.
The player who lost their dice starts the next round, unless they lost their final dice, in which case the player after them starts. Each player clicks "Roll" to get their new dice.
When a player loses their fourth dice, i.e. they have a single dice left for the first time, it is a special round called Palifico. In this round, ones do not count as wild, and the starting player can start by calling ones if they wish. After the first call, the dice value cannot change. So if the first player calls "one one", the second player could call "two ones", but not "one two". The round then continues as normal.
A player who is "ex-Palifico", i.e. lost their fourth dice but has survived to later rounds, has a special ability in any later Palifico rounds they take part in. An ex-Palifico player can increase the dice value, but without decreasing the dice quantity. So if the call is "one one", an ex-Palifico player may call "one two". But if the call was "one six", then the ex-Palifico player has no choice but to call "two sixes", or call Dudo, because they are not allowed to reduce the dice value.
When there are only two players remaining Palifico rounds do not apply.
If at some point in a round, you decide that the call that has just been made is exactly correct, and you are neither the person making the call nor the person who has to make the next call, then you can say "Calza" and click the button. At this point, the dice are shown and counted up as normal. If the call was exactly right, i.e. for a call of "five fives" there must be exactly five fives, including wildcards, then you won the call and should click the button. You will win a dice back, up to a maximum of five dice. If there were six fives, then you lost, should click the button, and forfeit a dice.
Calling Calza on a Palifico round is not allowed, nor if there are only two players in a round.
If you are the last player to have any dice remaining, congratulations you won!
If you need to leave the game before it is complete, use the menu button top right to access the button, which is only available at the beginning of a round. You will be asked to confirm your decision. When you leave the game your player and dice will be removed and play can continue as before. It is not possible to rejoin a game after leaving.
If you are in a game that has not yet started, simply closing the page is enough to leave the game.
This section shows a full example game between three players. For simplicity, each player only has three dice to start with. The game plays exactly the same with the normal five dice. We are playing as the player Roger.
The first rolls are to find the starter. Everybody rolls... and Alice wins.
Everybody rolls again to receive their first game dice. There are a total of 9 dice, each with 6 sides. That means each number will appear on average 9/6 = 1.5 times total. On normal rounds, dice with a value of 1 count as a wildcard, so including them in our count means each number 2-5 will appear on average 3 times total.
Alice makes the first call: two fives.
Roger's hand already has two fives, the one and the five, so he cannot call Alice a liar. There are two obvious choices: go to three fives (which is still a plausible call), or go to one one. When moving from a dice value of 2-5 to a value of 1, the quantity of dice always has to halve, rounding up if necessary. Since Alice called fives, that seems a safer bet: three fives
Bob makes his call: three sixes.
Alice calls Dudo on Bob's call, and so all of the dice are shown:
Bob's call is correct - two sixes and a one for a total of three sixes. Alice loses a dice.
Alice lost the previous round, so she makes the first call again.
Alice calls two sixes.
Roger's choice is three of something, or one one. Given that Alice called sixes, nothing we have points us to a call of three, so: one one
Bob calls three threes (moving from ones back to two-six means double the quantity, plus one)
Alice calls four threes.
There are eight dice remaining, four of anything is daft so Roger calls Dudo.
Unbelievably, Alice's call was correct. Roger loses a dice.
Roger lost, so he starts the next round.
Two ones is an excellent hand, but in a normal round starting on ones is not allowed, so a different call is needed. The aim is always to make a call low enough that the next person accept your call but high enough that you don't have to make another call. This isn't always possible... Starting with sixes means that Bob will have to increase the quantity, so: three sixes.
Bob calls two ones.
Alice calls Dudo...
...and loses a dice.
Alice has lost her last but one dice, which makes this a palifico round.
Alice calls one one. Ones are not wildcards on a Palifico round, and starting on ones is allowed.
On a Palifico round a normal player can't change the dice value, so Roger has no choice but to call two ones.
Bob calls Dudo.
Roger loses a dice.
Roger has lost his last but one dice, which makes this a palifico round.
Roger calls one five. It's a good idea not to lie on Palifico rounds.
Bob calls two fives.
Alice calls two sixes. Alice is ex-Palifico, so can change the dice value upwards only (she couldn't have called three fours, for example).
Roger calls three sixes.
Bob calls Dudo.
Bob loses a dice.
This is a normal round again. Ones are wild, and starting on a one is not allowed.
Bob calls one four.
Alice calls one five.
Roger calls one six.
Bob calls one one.
Roger calls Calza. This is a prediction that the call is exactly right. The person making the call, and the person receiving the call are not allowed to call Calza (so Calza is not allowed for two players).
Roger is correct, so wins a dice.
Roger won, so he is the starter.
Roger calls one four.
Bob calls three fours.
Alice calls two ones.
Roger calls Dudo.
Alice loses a dice, and is out of the game.
Roger is the next player after Alice, so he starts the next round.

Bob calls Dudo.
Bob loses a dice.
Bob lost, so starts the round.
Bob calls one three.
Roger calls one one.
Bob calls Dudo.
Bob loses a dice.
Bob has lost his last but one dice, but there are only two players so this is not a Palifico round.
Bob calls one six.
Roger calls one one.
Bob calls Dudo.
Roger loses a dice.
Roger lost, so starts the round. One dice each, this is a normal round and the most stressful round of the game.
Roger calls one five.
Bob calls one one.
Roger calls Dudo.
Bob loses a dice, and Roger wins the game.
Just a note - this example was meant to show certain situations that arise in the game: don't take it as a strategy guide.
There is a user preference for controlling sound effects, available in the drop down menu accessible through the cog icon.
Before the game starts, it is possible to change some options. The host player, normally the first player to create the game and indicated by a lightning icon, is the only player allowed to change the game options.
The host player has the ability to remove players from a game at the end of a round. To do this, click on the player name and then confirm your decision.
