In Liar’s Bar , the Liar’s Deck mode uses 1 to 3 cards per turn, played face down. The game also has a separate Liar’s Dice mode, so “cards” only applies to the deck variant.

Quick Scoop

  • Cards per play: 1–3 cards
  • Mode name: Liar’s Deck
  • Separate mode: Liar’s Dice, which uses dice instead of cards

What that means

If you were asking how many cards are in the hand or deck overall, the sources I found don’t give a single fixed total. They do confirm that in the card mode, players announce and play up to three cards at a time, then others can call the bluff.

TL;DR

For Liar’s Bar / Liar’s Deck , the number you’re looking for is 1–3 cards played per turn.
