Lie about your cards... or get caught bluffing.
El Mentiroso depends more on who you are playing with than any other game in the house. Four to six is where it sits best: enough eyes on each play that lying costs something, and a pile that does not grow so fast that challenging is suicide.
Before the deal, the host picks whether the called rank stays fixed for the whole round or climbs by one each play. The ascending variant changes the game a lot: you can work out what you will have to call ahead of time and set up the bluff.
Because cards are played face down, challenging is a button: anyone can call "Liar!" at any point before the next play resolves. The table reveals the cards and hands out the pile automatically.
In a private room the mode is set by whoever creates it and does not change mid-game, so it is worth agreeing on before the deal.
On a public table no host decides this: everyone votes for the option they want and the tally shows on each button.
Cards are played face down, so nobody can see whether you told the truth. All the table sees is how many cards you put down and what rank you called: everything else is whatever you manage to sell.
Challenging is a button, and anyone can press it, not just the player after you. It resolves itself: the table turns the cards over and hands the pile to whoever has to carry it.
The clock is twenty-two seconds, longer than most games in the house, because the decision here is not mechanical - it is reading people.
