Ride the BusThe Complete Rules
Also known as: Bus Driver · Riding the Bus · Bussen (Scandinavia)
Ride the Bus is a card-based drinking game played in three phases. First, each player answers four prediction questions about the next card. Next comes the Pyramid: a face-down stack of cards flipped one at a time, with players giving and bluffing drinks. Finally, the player with the most cards left in hand has to "ride the bus" — guessing through a punishing card sequence that resets on every wrong answer.
It plays in 20 to 40 minutes with 4 to 10 players and one deck. Below: full rules for all three phases, the actual odds behind every guess, and the house rules worth adding.
What is Ride the Bus?
Ride the Bus is a card-based drinking game built around prediction. Each phase reuses the same four prediction questions — red or black, higher or lower, inside or outside, and suit — but layers them into different group dynamics. In Phase 1, each player makes the predictions in turn. In Phase 2 (the Pyramid), the cards are predicted collectively while players bluff drink-credits across the table. In Phase 3, one unlucky player has to clear the entire prediction sequence in one clean run.
The game spread out of Scandinavian student bars (where it's called Bussen) and became a fixture at North American college parties through the 2000s. Today it's the most-played multi-phase card drinking game in English-speaking countries, edging out Pyramid and President for groups that want more than just "draw and drink".
The simplified "pub version" of Ride the Bus is just Phase 1 played until someone gets all four right in a row. The full game on this page is the three-phase Pyramid version, which is what most American and Northern European groups play. If your friends only know Phase 1, ride the bus into Phase 2 — you'll never go back.
What you need & how to set up
Setup takes about a minute:
- One standard deck. 52 cards, jokers removed.
- Drinks for each player. Beer is traditional; cocktails work too. Avoid shots-only — Phase 2 can stack drinks fast.
- Pick a dealer. Whoever shuffled, or rotate clockwise from a previous round. The dealer doesn't play Phase 1 — they ask the questions and flip the cards.
- Seat the players. Round table is best, but a sofa cluster works. Everyone needs to see the dealer's hand.
Before Phase 1: shuffle. Phase 1 will use 4 cards per player, so for 6 players you'll burn 24 cards before the Pyramid begins. Keep that in mind if you have a small deck or a lot of players.
The Four Questions
Each player answers four prediction questions in order. Right = give drinks. Wrong = take drinks.
Going clockwise from the dealer's left, each player faces the same four-question sequence. The dealer flips one card per question in front of that player, and the player keeps every revealed card face-up in front of them. By the end of Phase 1, every player has a four-card "hand" sitting in front of them — these stay visible and matter for Phase 2.
Four stops in fixed order. Make it through clean and you skip the next phase's drinking — almost.
The questions, in order
Red or Black?
Guess the color of the first card. Hearts and Diamonds are red, Clubs and Spades are black. The dealer flips the card and you find out instantly.
Wrong: drink one. Right: give one. Tie: not possible.
Odds: 50 / 50Higher or Lower?
Will the second card be higher or lower in value than the first? Aces are usually high. If the second card matches the first card's value, that's a loss in most house rules — drink double.
Wrong: drink two. Right: give two. Tie: drink double (most rules).
Odds: depends on card 1Inside or Outside?
Will the third card fall numerically between the first two cards (Inside) or outside that range (Outside)? Equal to either of the first two = drink double.
Wrong: drink three. Right: give three. Tie: drink double.
Odds: depends on cards 1+2Suit?
Which of the four suits is the fourth card? Hearts, Diamonds, Clubs or Spades. Pure 25% guess — you cannot improve your odds with information from the previous three cards.
Wrong: drink four. Right: give four. Tie: not possible.
Odds: 25 %The actual odds (a quick math interlude)
The total Phase 1 expected drinks for a single player, assuming you guess randomly:
| Question | Win odds | Drinks if wrong | Expected drinks |
|---|---|---|---|
| 1 — Red or Black | 50% | 1 | 0.5 |
| 2 — Higher or Lower | ~58%* | 2 | 0.84 |
| 3 — Inside or Outside | ~50%* | 3 | 1.5 |
| 4 — Suit | 25% | 4 | 3.0 |
| Phase 1 total | ~5.8 |
* Higher/Lower averages around 58% for an optimal player who picks the side with more remaining cards (a 6 has more room to move higher than lower, etc.). Inside/Outside is closer to 50% on average but skews toward Outside when the gap between cards 1 and 2 is small.
The first two questions cost you about 1.3 expected drinks combined. Question 4 alone costs 3 — half of all your Phase 1 drinks come from a guess where you have no information. Don't agonize over Q4; you can't improve the odds. Save your concentration for Q2 and Q3 where math actually helps.
The Pyramid
A face-down stack of cards is flipped one at a time. Players give and bluff drinks based on what they hold.
After everyone has finished Phase 1, every player has a four-card "hand" sitting face-up in front of them. The dealer takes the remaining deck and arranges a pyramid, face-down, with rows of increasing size from top to bottom. Most groups use a 5-row pyramid (1+2+3+4+5 = 15 cards). Smaller groups can use 3 or 4 rows.
Cards are flipped from the bottom row up. Each row's number is the drink-stake on its cards.
How the Pyramid round plays
The dealer flips cards one at a time, starting from the bottom row and moving up. For each card flipped:
- If you have a card in your hand with the same value as the flipped card (suit doesn't matter), you can choose to "give drinks" — point to any player and tell them to drink the row's number.
- You can bluff — pretend to have a matching card you don't have.
- The targeted player can "call it" — challenge the bluff. If the giver has the matching card, the caller drinks double. If they don't, the bluffer drinks double and gets caught.
- You can split a row's drinks across multiple players (e.g., row 4 = give 2 drinks to player A and 2 to player B). House rules vary on whether you can split your own bluff.
- Once you've used a card to give drinks, it's "spent" — flip it face-down. Spent cards can't be used again.
Higher rows are more valuable: by the time you reach row 5 (the bottom of the flip order, but the last to be revealed in some house rules), drinks are worth 5 each. Save your high-value matches for late if you can — but that means risking that you won't see another match at all.
The expected value of a bluff is positive when you think there's less than 50% chance of being called. Beyond that, you double your own drink. In groups that don't bluff much, calling rate is closer to 30–40%, which makes bluffing a strong default. In groups that call everything, bluffing only pays when the row is small (rows 1 and 2).
Riding the Bus
One player faces a 5-to-10 card sequence. Each card asks one of the four prediction questions. One miss = restart from the start.
At the end of Phase 2, count each player's remaining hand cards. The player with the most cards left rides the bus. If two players tie, they play a single Phase 1 question (red or black) to decide. Some house rules tie-break by total drinks given in Phase 2 instead — pick one before you start.
Six cards face-down. The questions cycle through the four Phase 1 questions in order.
How the Bus runs
- The dealer lays 6 cards face-down in a row (5–10 is acceptable; 6 is most common).
- Starting at card one, the rider answers the first Phase 1 question (Red or Black). Card is flipped — right or wrong is immediate.
- If correct: move to card two and answer the next question (Higher or Lower). Right again? Card three (Inside or Outside). And so on through Suit, then back to Red or Black for card five.
- If wrong: drink one (or the row's number, in some house rules), reshuffle the wrong card back in, and start again from card one.
- The rider must reach the end of the bus with no errors. Once they hit the last card cleanly, the game ends and the next round begins.
The catch: every restart costs at least one drink. A truly unlucky run — failing repeatedly on Suit (Q4, the 25% guess) — can produce 10+ drinks before the rider gets off. Most players plead with the dealer to use a 5-card bus if they're already deep into Phase 2.
The expected number of drinks to clear a 6-card bus, assuming optimal play, is around 9 drinks. The hardest single card is Q4 (Suit) at 25% — clearing it means a 75% chance of restart on that single attempt. Most groups that finish the bus do so on luck, not skill.
House rules & variants worth knowing
Beyond the per-question variants noted above, most regular Ride the Bus groups end up adding two or three of these to the standard ruleset. Pick a version, agree before Phase 1, and don't change it mid-game.
Snap on a tie
If the second card matches the first card's value (or third matches first/second), instead of "drink double" the dealer and the player both drink the row's amount. Friendlier for new players.
Mini pyramid
Use 3 rows (1+2+3 = 6 cards) instead of 5. Cuts Phase 2 in half. Recommended for 4-player games or when the night is already past midnight.
Top-down flip
Reverse the flip order: start from row 1 (the top, smallest stake) and end on row 5 (the bottom). Drinks escalate as the round progresses, building tension toward the end. Default in most US versions.
Mini bus
5-card bus instead of 6 or 10. The rider's expected drink count drops from ~9 to ~6.5. A common mercy rule for late-game.
Doubling bus
Each restart adds one more card to the bus length. Brutal — used in tournaments or as a punishment when someone is already winning the night. Don't use this with new players.
Sober mode
Replace alcohol with non-alcoholic drinks (or just gestures). The math, the bluffs and the bus tension all still work. Surprisingly fun even sober — it's a real prediction game underneath.
How not to ride the bus
The expected drinks for an unlucky Phase 1 + Phase 2 player can hit 15+. Some of that is luck, but most of the variance comes from three decisions where math and reading the table actually matter.
Phase 1: pick the right side on Higher/Lower
If your first card is a 6, there are 7 ranks higher (7-A) and 5 ranks lower (2-5) — go higher. Always pick the side with more cards remaining. Aces are usually high (so a 9 should still go higher; only 10/J/Q/K/A above it, but 4 of each = 20 cards above, vs 7 ranks below × 4 suits = 28 cards). The exception: when the dealer hands you something extreme (a 2 or an Ace), the call is obvious — go the only sensible direction.
Phase 2: bluff into small rows, give honestly into big rows
The bluff math: when you bluff and get caught, you drink double the row's stake. Small rows (1, 2 drinks) are cheap to lose; big rows (4, 5 drinks) are expensive. Save your bluffs for early rows when nobody is paying attention. By the time the dealer reveals row 5, the table is alert — bluffs there get called twice as often.
Phase 3: if you must ride the bus, ask for the smallest one
Cleanly: the difference between a 5-card and a 10-card bus is roughly 5 expected drinks for the rider. If you're entering the bus already drunk, a 5-card mercy bus costs the table almost nothing in vibes but saves you significantly. Most groups will agree — especially if it's late.
Question 4 (Suit) is the single biggest source of variance in the entire game. It's a flat 25% guess, and on the bus it appears at every fourth card. There's no skill or read that helps. Do not stress about it — accept that Suit will get you about 75% of the time and breathe through it.
Ride the Bus: frequently asked questions
What is Ride the Bus?
Ride the Bus is a three-phase card-based drinking game for 4 to 10 players. Phase 1 has each player answer four prediction questions about the next card. Phase 2 is the Pyramid, a give-and-bluff drinking round. Phase 3 is the Bus itself: one player guesses through a face-down sequence of cards, restarting from the top on every wrong answer.
How many players do you need?
Four is the minimum, eight is the sweet spot, and ten is a comfortable maximum. Fewer than four makes Phase 2 too short and gives the bus rider nobody to bluff against. More than ten and you start running out of deck during Phase 2.
How long does Ride the Bus take?
Plan for 20 to 40 minutes per round depending on group size. Phase 1 takes about 5 minutes per four players, Phase 2 about 10 minutes, and the Bus itself can range from one minute to fifteen depending on how many restarts the rider triggers.
What are the four questions?
Red or Black (the color of card 1), Higher or Lower (card 2 vs card 1), Inside or Outside (is card 3 numerically between cards 1 and 2), and Suit (which of the four suits is card 4). They're answered in this exact order.
What happens on a tie in Phase 1?
Most house rules treat a tie (the second card matches the first card's value, etc.) as a loss for the player — they drink double. Some groups use 'snap': both the player and the dealer drink the row's stake. Pick a rule before you start.
Who is the bus driver?
Two different things in two different versions. In most American variants, the dealer is informally called the bus driver, but the player who 'rides the bus' is whoever ends Phase 2 with the most cards left in hand. In other versions, 'bus driver' is just a nickname for the dealer.
How long is the bus in Phase 3?
Five to ten cards is standard. Six is the most common length. Each card requires one of the four prediction questions in rotating order. Wrong answer = restart from card one.
Is Ride the Bus the same as Bussen?
Yes — Bussen is the Danish, Norwegian and Swedish name for the same game. The phases, the questions and the bus mechanic are identical. The only common difference is house-rule layering — Scandinavian versions often use a smaller pyramid (3 or 4 rows instead of 5).
The bus is loading. Who's the driver?
You've got the rules, the math, and the variants. Grab a deck, four friends, and pull out — and when the bus has done its run, Dronk is in your pocket.
