Games Laboratory

Four tools to better understand the cards in your hand: calculate odds, keep track of your games, deal decks at will and test what you know. They work on mobile, without registration and offline once opened.

What each one is for

Odds calculator

What are my chances of getting something?

Choose a deck, how many cards are drawn and what you are looking for: an As, two oros (coins), a figure… and get the exact result with its explanation.

Open

Game scoreboard

Who is winning and how many points do they have?

Record rounds of Escoba, Brisca, Tute, Guiñote, Mus, Pocha, Chinchón or Continental with the rules of each game, and organise championships.

Open

Deal simulator

How could the cards fall?

Shuffle and deal like at the table, fix known cards, repeat a deal with its code or run thousands to see what usually comes out.

Open

Challenges

How much do I know and how good am I?

A new challenge every day and another every week: deck culture, probability, memory, logic, strategy and speed.

How they are made

  • The calculations are exact: when something is a simulation or an estimate, we indicate it.
  • Rules that change according to the region or the table are presented as variants, never as the only way to play.
  • Nothing leaves your device: there is no registration or personal data.
  • The tools do not touch online games: they are a testbed for learning.

FAQ

Are the tools free?

Yes. They are all free, do not require an account and can be used as many times as you like.

Can I use the scoreboard in a real game with friends?

That is what it is designed for: large screen, comfortable buttons and the game saved on your mobile even if you close the page.

Are the simulator deals really random?

Yes. They are shuffled with the browser's secure random number generator and the Fisher-Yates algorithm, the same method that guarantees every possible order of the deck is equally likely.

Is money involved or is anything bet?

No. The laboratory is for learning and enjoying the deck as a tradition; nothing is bet here.
