Dudo
Peek at your dice in secret and bet how many are on the table. Don’t believe the last bid? Call it!
How to playHow to play
Dudo is PASANDOLA's dice cup, a digital version of the classic Chilean dice game, also known as cacho or liar's dice. Every player opens the game on their own phone, shakes to roll their five dice, peeks at them in secret and keeps count of how many they have left. The game itself is played in real life, face to face, trying to work out who is lying.
Unlike the other PASANDOLA games, here every player uses their own phone. There are no rooms, no accounts and no link between the phones, so it works for any table of 2 to 10 people, straight from the browser with nothing to download. The app does not referee and has no idea what the others rolled, it just replaces the physical cup and dice.
- Every player opens Dudo on their phone and the table agrees on the same rules.
- You shake your phone or tap Roll and the cup shuffles your five dice, which stay covered.
- You press and hold the cup to peek at your dice in secret, and when you let go they are covered again.
- In turns, each player bids out loud a quantity and a face over all the dice on the table.
- Whoever doesn't believe the previous bid challenges it, and everyone lifts their cup and counts.
- Whoever loses tells the table and taps the lose a die button on their screen.
- The last player who still has dice wins the game.
The cup
This is the main screen. You shake to roll and press and hold to peek, so nobody sees your dice except you. If your phone has no motion sensor, the Roll button does the same thing.
Your dice
A big counter shows how many dice you have left, with buttons to subtract one when you lose and add one when you get one back. The app only counts your dice and nobody else sees them.
The lifeline
If you are not sure what to say, open the lifeline and enter the previous bid. The app shows every valid answer, plus how many dice your own dice add and how many are expected among the others.
The help screens
There is a guide with the full rules and a what do I do now panel for each situation, such as losing a die, calling spot on or running out of dice.
Who wins
The app does not decide. The last person who keeps at least one die wins, and the table confirms it out loud.
Dudo rules
There is no official rulebook and Chilean versions differ in the details. This game adopts the set of rules below and leaves the variable parts as table rules, which each group picks before starting.
The faces
From lowest to highest they are ace, then the faces from two to six, which in the Chilean cacho are called tonto, tren, cuadra, quina and sexto. Aces are wild and count as any face, except in a forced round.
Bidding
Every player starts with five dice. Whoever opens bids a quantity and a face over all the dice on the table, for example three threes. The next player must raise the quantity, raise the face or both.
Switching to aces
You can lower the quantity if you bid aces. With an even quantity it goes to half plus one or to half, depending on the table rule, and with an odd quantity to half rounded up, so seven threes become four aces. To go back to another face you must bid double plus one.
Challenging
Every cup is lifted and the dice are counted, with aces as wilds. If there are fewer than the bid the bidder loses a die, and if there are as many or more the challenger loses a die.
Spot on
It means claiming there are exactly as many as the bid. It is only allowed if at least half of the starting dice are on the table, or if the player calling has a single die. A correct call gets a die back, or a spare die if the player already has five. A wrong call loses a die.
Forced round
The first time a player is down to a single die, they force the next round and choose open or closed. In an open round everyone sees the other dice but not their own, and in a closed round only whoever forces sees their die. In that round aces are not wild and the face is fixed, unless another player also has one die and can change it.
Who starts
The next round is started by whoever lost the die or called spot on correctly.
Frequently asked questions
Do I need internet?
Only to open the page. Once it has loaded, Dudo makes no network requests during the game. If you close the tab you need a connection to open it again, and when you come back you can pick the game up where you left it.
Does the app know who wins?
No. The app does not referee and has no idea what the others rolled, because every phone is independent. Players announce out loud who loses, calls spot on or forces a round, and each one adjusts their own counter.
What happens when I have one die left?
If the table has forced rounds turned on, the first time you are down to a single die you force the next round and choose open or closed. Also, with a single die you can call spot on even when fewer than half of the dice are left on the table.
When can I call spot on?
When at least half of the dice the game started with are still on the table, or when you have a single die. The lifeline tells you whether you can at that moment. With five dice per player, a table of four starts with 20 dice and you can call spot on as long as 10 or more remain.
