Bullshit (a.k.a. Cheat / I Doubt It) — Complete Rules

This is a complete, unambiguous ruleset for the card game Bullshit, written to settle the "house rule" gaps that so often come up mid-game. Where multiple common variants exist, the Standard Rule is marked, and common alternatives are listed as Optional Variants you can agree on before dealing.

1. Overview

Bullshit is a card-shedding game of bluffing and memory. Players race to be the first to get rid of all their cards by placing them face-down in a central pile while claiming a rank (e.g., "two Sevens"). Players do not have to tell the truth about what they played. Any other player who suspects a lie may challenge by calling "Bullshit!" The loser of a challenge (either the liar, if caught, or the challenger, if wrong) picks up the entire discard pile into their hand.

• Players: 2–8 (best with 4–6; see Section 11 for scaling notes)
• Cards: One standard 52-card deck (no Jokers) for up to ~6 players. For 7–8 players, use two combined decks (104 cards) — see Section 11.
• Objective: Be the first player to have zero cards in hand.
• Core tension: You must play a card (or claim to) on your turn; you may lie about what you played; other players may call your bluff.

2. Components

• 52-card standard deck: ranks Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, in 4 suits (Clubs, Diamonds, Hearts, Spades). Suits and card "power" never matter in this game — only rank matters, and only for the purpose of matching a claimed rank.
• No Jokers used by default (Optional Variant: include Jokers as wild cards — see Section 10).

3. Setup

1. Shuffle the deck thoroughly.
2. Deal the entire deck out one card at a time, face-down, to all players in clockwise order, until the deck is exhausted.
   • Hand sizes may be uneven if the deck doesn't divide evenly among players (e.g., 52 cards / 5 players = 10, 10, 11, 11, 10). This is normal and not an error.
3. Players may look at their own hands but must keep them hidden from others.
4. Determine the starting rank and starting player:
   • Standard Rule: The starting rank is always Ace, and the player to the dealer's left goes first. Play proceeds in ascending rank order from there (see Section 5).
   • Optional Variant: Randomly determine the starting player and starting rank (e.g., deal or draw to determine).
5. A discard pile (a.k.a. "the pile" or "the center pile") starts empty in the middle of the table.

4. Turn Order and Direction

• Play proceeds in a single fixed direction (clockwise by default, though the table can agree on counter-clockwise) and does not change during the game.
• Exactly one player acts at a time, in what is called a turn.
• A turn consists of:
  1. The active player makes a play (Section 5).
  2. A challenge window opens in which any other player may call "Bullshit!" on the play just made (Section 6).
  3. The challenge (if any) is resolved (Section 6).
  4. Turn passes to the next player in turn order — regardless of whether a challenge occurred or who picked up cards (see Section 6.4 for the important edge case of what happens when the active player themselves is forced to pick up the pile).

5. Making a Play (The Core Mechanic)

5.1 Rank sequence

The game is built around an ascending (or descending) rank cycle that dictates what rank must be claimed on each turn. The default cycle is ascending from Ace to King, then wrapping back to Ace:

A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, (back to A), ...

• Standard Rule: The claimed rank is forced — each player must claim the next rank in the sequence, one greater than the rank the previous player claimed (wrapping King → Ace). Players cannot choose what rank to claim; the sequence dictates it. This is the classic "Bullshit" mechanic and the primary source of forced bluffing (you must claim a rank whether or not you hold cards of that rank).
• Optional Variant ("Free Call"): Players may freely announce any rank they wish on their turn, with no forced sequence (this is common in the "Cheat" variant). If this option is used, there is no sequence to track; the acting player simply states any rank.
• Under the Standard Rule, the required rank keeps advancing one step every turn — regardless of whether the previous play was truthful, whether it was challenged, or who ended up picking up the pile. The sequence only depends on turn order, never on challenge outcomes.

5.2 What a play consists of

On their turn, the active player must:

1. Choose 1 to 4 cards from their hand to place face-down onto the discard pile (a player cannot claim more copies of a rank than physically exist — see 5.3 — and cannot play 0 cards; if a player has any cards in hand they must play at least 1).
2. Announce out loud (or via UI action) a claim of the form: "[quantity] [rank]s" — e.g., "two Sevens," "one Jack," "four Aces."
   • The quantity claimed must equal the number of cards physically placed face-down. A player cannot say "three Kings" while only placing two cards — the claimed quantity always matches the physical count placed; only the claimed rank can be a lie.
   • The rank claimed must be the current required rank per the sequence (Standard Rule) or any rank of the player's choosing (Free Call option).
3. The cards are placed face-down on top of the discard pile, merging with cards already there. Once placed, a player's own cards are indistinguishable from the rest of the pile to everyone else — no one knows their true identity until a challenge forces a reveal.

5.3 Truthfulness is optional, quantity claims are not

• The cards physically played may or may not actually be of the claimed rank. A player may play any cards from their hand face-down while claiming any rank permitted by 5.1 — this is the "bluff."
• A player is not required to have any cards of the claimed rank in order to make a legal play. Even a player with zero cards of the required rank must still play something (this forces bluffing to be a core, unavoidable mechanic — not an edge case).
• Quantity constraint: A player may play between 1 and 4 cards (since there are only 4 cards of any rank in a single 52-card deck). With multiple merged decks (Section 11), more copies of each rank exist, but the Standard Rule still caps a single play at 4 cards regardless of deck count, to keep bluffing meaningful. Some groups raise this cap as a house rule when playing with merged decks.
• A player may choose to play fewer cards than they hold of a rank (true or claimed) — e.g., holding three real Sevens but only playing one and claiming "one Seven" is legal and often a smart hedge against being challenged.

5.4 What Other Players Can See

Other players only ever see the number of cards placed and hear the claimed rank — never the true identity of the cards played, unless a challenge forces a reveal. See Section 9 for the full rundown of what's public information at every point in the game.

6. Challenging ("Calling Bullshit")

6.1 Who may challenge and when

• After a play is made, there is a challenge window during which any one or more of the other players may call "Bullshit!" (i.e., publicly accuse the active player of lying about the rank).
• Standard Rule: Any player other than the one who just played may call Bullshit, including players who are not immediately next in turn order. The active player who just played cannot challenge their own play.
• Standard Rule — multiple simultaneous challenges: If more than one player calls Bullshit on the same play at once, only the first challenge counts; everyone else is too late, since one challenge fully resolves the play.
• Standard Rule — challenge timing: A challenge must be made before the next player begins their own play (i.e., before the next card(s) are placed on the pile). Once the following player has placed their own cards and made their claim, the previous play can no longer be challenged, and only the new play is challengeable.
  • Optional Variant: Allow challenging any play still visibly "on top" of / traceable in the pile, even after subsequent turns have passed, as long as no one has picked up the pile since. Not recommended — it gets confusing fast; most groups stick to "only the most recent play is challengeable."
• A player is never required to challenge; declining to challenge is always legal and simply passes the turn onward.

6.2 Resolving a challenge

When a challenge is made on the most recent play:

1. The cards from that specific play only (i.e., only the most recently placed 1–4 cards, not the entire pile) are revealed face-up to all players.
2. Compare the revealed cards' true ranks to the claimed rank:
   • If ALL revealed cards match the claimed rank → the claim was truthful. The challenger was wrong and must pick up the entire discard pile (every card currently in the pile, including the just revealed ones) into their own hand.
   • If ANY ONE (or more) of the revealed cards does NOT match the claimed rank → the claim was a lie ("caught bluffing"). The active player who made the play must pick up the entire discard pile into their own hand.
3. After the pile is picked up by whichever player lost the challenge, the discard pile is empty, and play continues.
4. All picked-up cards go into the receiving player's hand as normal playable cards (shuffled into their hand order is irrelevant — hand order never matters in this game).

6.3 No challenge made

• If the challenge window passes with no challenge, the play stands unchallenged (its truthfulness is never revealed to anyone), the cards remain face-down in the pile, and play simply passes to the next player.

6.4 Important edge case: turn order after a pickup

• Regardless of who picks up the pile (challenger or bluffer), the very next turn belongs to the player immediately after the one who made the just-resolved play, in normal turn order — even if that next player is the one who just picked up the entire pile.
  • Example: Player A plays and claims "one Jack." Player B (next in turn order) challenges. Player A was lying, so Player A picks up the pile. Play now proceeds to Player B — B still takes their turn next (claiming "Queen" per the sequence), immediately after having done the challenging, since B was already next in line. B does not skip their turn and does not get to challenge again on the same play.
  • Example: Player A plays and claims "one Jack." Player C (not immediately next) challenges instead of B. Player A was telling the truth, so Player C must pick up the pile. Turn order is unaffected by who challenged — play still proceeds to Player B next (the player immediately after A), not to C. Turn order is strictly seating-order based and is never altered by who challenges or who picks up cards.
• Picking up the pile does not grant or skip a turn — it only adds cards to a hand. The rank sequence (Section 5.1) also continues to advance normally regardless of pickups.

6.5 Simultaneous / group challenge variant (Optional Variant)

Some house rules allow every player except the active player to independently decide whether to challenge, and if any of them challenges, the single resolution in 6.2 applies once — challengers don't separately pick up cards from each other. In practice this plays out the same as "first challenge wins," just with everyone free to shout at once. Not part of the standard game.

7. Ending a Player's Turn Without Playing

• There is no pass/skip option for a player's core play — a player with at least one card in hand must play between 1 and 4 cards (per Section 5.2) on their turn, truthfully or not. There is no legal way to decline making a play while holding cards.
• The only ways a turn resolves without new cards leaving a player's hand are (a) they have zero cards already (they have won — see Section 8), or (b) they lose a challenge and pick up the pile (their hand grows, but this happens after their play is already completed for that turn).

8. Winning the Game

• Standard Rule: The first player to have zero cards remaining in hand at the moment their hand becomes empty is the winner, and the game ends immediately.
  • A player's hand becomes empty only as a direct result of playing their last card(s) as part of a normal turn (Section 5.2).
  • Critical edge case: A player who empties their hand is still subject to being challenged on that final play, exactly like any other play. If challenged and caught bluffing, they must pick up the entire pile and are therefore back in the game with a full hand again — they have not won. If challenged and found truthful (or not challenged at all), they have genuinely emptied their hand and win immediately.
  • The challenge window (Section 6.1) still fully applies on a game-ending play before the win is confirmed — nobody can be declared the winner while their final play is still open to being challenged.
• If the winning player's final play is not challenged, or is challenged and they are vindicated, the game ends immediately — no further turns occur, and no one else needs to also empty their hand.
• Optional Variant — play for last place ("loser" variant): After the first player empties their hand and wins, continue play among remaining players (skipping the winner's turns entirely) until only one player remains holding cards; that player is the outright "loser." Not part of the standard game — the standard game ends at the first winner.

9. What's Public Information

Because the game turns on bluffing, it matters exactly what everyone can and can't see at any given moment:

• Your own hand is visible only to you.
• Cards just played are face-down and unidentifiable to everyone else until a challenge forces a reveal — even then, only that specific play's cards are shown, never the rest of the pile.
• The claimed rank and quantity of the current play, and the running size of the discard pile, are announced and visible to everyone.
• How many cards each opponent holds is always visible as a count — though never which cards. Watching hand sizes shrink is one of the main ways players judge who's close to winning and worth challenging.
• Past claims made earlier in the game are part of the shared history everyone remembers, even though the cards behind them (if unchallenged) are still hidden inside the pile.

10. Common House-Rule Variants (Optional Variants)

1. Free Call (Section 5.1) — players may call any rank each turn instead of following the forced ascending sequence; common in games that go by the name "Cheat."
2. Descending sequence — run the forced sequence King down to Ace instead of Ace up to King.
3. Different starting rank — begin the sequence somewhere other than Ace.
4. Higher max cards per play — raise the 4-card cap, most often when playing with merged decks (Section 11).
5. Counter-clockwise play instead of clockwise.
6. Include Jokers as wild cards — if used, a Joker can be played as part of any claimed rank and always counts as a truthful match, so it can never get a bluff caught when revealed. Most groups add 2 Jokers when using this variant.
7. Play until last-place / "loser" determined — Section 8.
8. Multi-deck play for large groups (see Section 11).
9. Penalty-card variant: Some house rules say that a legitimate four-of-a-kind, played openly, is removed from the game entirely rather than ever risking a pile pickup. Not part of the standard ruleset, but a popular house addition.
10. Table talk: Whether players may verbally bluff, mislead, or make claims about their hand outside of the formal claimed-rank announcement — this is a purely social layer with no effect on the actual rules, and is unrestricted by default. (One thing that's always a hard rule, not a variant: a player can never challenge their own play.)

11. Scaling: Player Count and Deck Size

• 2 players: Playable, if a little repetitive — with only two players, the "next player" after any pickup is always the same single opponent, so play just alternates strictly back and forth. Still deal the whole deck evenly and use the standard rules; it's a valid, if intense, 2-player experience.
• 3–6 players: Standard single 52-card deck, dealt evenly (with remainder cards distributed one-by-one starting from the first player, per Section 3).
• 7–8 players: Standard Rule: combine two 52-card decks (104 cards total, no Jokers unless the Section 10 variant is used) and deal the entire combined pool evenly. Even though there are now 8 copies of each rank in play, the max cards per play stays at 4 unless the table specifically agrees to raise it.

12. Common Misconceptions and Clarifications

A handful of rules trip up new players (and even experienced ones) more than anything else in the game:

• The claimed quantity always equals the number of cards actually placed — it's only the rank claim that can be a lie.
• A player with zero cards of the required rank must still play (forced bluff) — there is no pass.
• Only the most recently played cards are revealed on a challenge — never the entire pile's history.
• The entire pile — not just the challenged cards — goes to whoever loses the challenge.
• Turn order always advances to the next player in normal seating order, regardless of who challenged or who picked up the pile — a pickup never grants an extra turn or skips a turn.
• The forced rank sequence keeps advancing one step every turn, regardless of the challenge outcome.
• A player can go out and still be legitimately challenged on that very last play — they only actually win if the challenge resolves in their favor, or no one challenges at all.
• A player can never challenge their own play.
• Once the next player has made their own play, the previous play can no longer be challenged.
• Uneven hand sizes are normal whenever the deck doesn't divide evenly among players — not a mistake in the deal.
• Card counts (not identities) of opponents' hands are public information throughout the game.
