My game is a small twist on the traditional 'Bluff' card game. 

Here, I setup a 4-player “Cheat/I Doubt It” game: each turn there’s a Lead Rank (A,2…10,J,Q,K). On your turn you either Play 1–4 cards face-down and claim they match the Lead Rank (you may bluff), or Pass (which advances the Lead Rank to the next value and moves turn on). After any claim, the next player has 100 seconds to Check (challenge) or Don’t Check. If they Check and the claim was true, the challenger takes the entire face-down pile into their hand; if the claim was a bluff, the liar takes the pile. First player to empty their hand wins. Suit of the card doesn't matter only it's rank matters in this game. Example: Lead Rank is 5; you play two cards face-down and say “two 5s.” If an NPC checks and you actually played 5♥ and K♣ (one isn’t a 5), you bluffed and must take the pile; if you truly played two 5s (eg. 5♥ and 5♣), the NPC takes the pile instead. (You can also chat—e.g., “Vector, are you bluffing?")
