Overview
Everyone builds a face-up line of cards. Another draw can improve your score or wipe out the whole round if it repeats a number.
Edition scope. Base game, English ruleset 3.1 (2025). Compare the printed rules in your box, especially Flip Three timing. Not Flip 7: With A Vengeance. For more than 18 players the publisher recommends a second deck.

Objective
Have the highest total when a round ends with at least one player on 200 or more points.
Setup
- Shuffle all 94 cards well. Prepare a score sheet and choose a dealer; the dealer also plays.
- Numbers are unevenly distributed: one 0, one 1, two 2s, three 3s, and so on up to twelve 12s. There are also six score modifiers and nine action cards.
- Deal one face-up card to each player in turn order, including the dealer. Pause to resolve action cards immediately, then continue the initial deal. Not everyone necessarily starts with a Number card.
How to play
Initial deal → on your turn Hit or Stay → resolve cards → everyone stops or someone gets seven different numbers → score.
Hit or Stay
On your turn, Hit to receive one face-up card, or Stay to bank your current round score and leave the round. Skip players who have already stopped or busted. You may Stay once you have a card in front of you.
Check numbers
Keep a new number. A number already in your line makes you bust for 0 this round, unless Second Chance saves you. Zero counts as a unique number even though it scores 0.
Resolve special cards
Keep score modifiers. Use Freeze or Flip Three on an active player, including yourself; if only you remain active, target yourself. See the action table below for Second Chance and forced draws.
End the round
Seven different Number cards immediately end the round for everyone and give that player +15. Otherwise continue until nobody is active. Everyone who did not bust scores their line.
| Card | What happens |
|---|---|
| Freeze | The target banks their current score and exits the round. |
| Flip Three | The target takes up to three cards, one at a time. All card types count toward three. Stop early on a bust or Flip 7. Second Chance can protect them during these draws. |
| Actions inside Flip Three | Set aside Freeze and further Flip Three cards until the three-card sequence finishes. Under ruleset 3.1, resolve them only if the receiver did not bust. A Flip 7 ends the round immediately. |
| Second Chance | Keep one. On a duplicate number, discard the newly drawn duplicate and Second Chance; keep the original number and continue. A second Second Chance goes to another active player without one, or is discarded if nobody can receive it. Unused protection expires after the round. |
| +2, +4, +6, +8, +10 | Add these bonuses after calculating Number-card points. These are not Number cards. |
| ×2 | Double only the Number-card sum; then add modifier bonuses and any +15 Flip 7 bonus. |
Worked example
Your numbers are 11, 5, 12, with ×2 and +4. Staying banks (11 + 5 + 12) × 2 + 4 = 60. Drawing another 12 would bust you unless Second Chance protects you.
Seven cards in total is not necessarily Flip 7: you need seven different Number cards.
Ending & scoring
Record each round: a bust scores 0; otherwise sum Number cards, apply ×2 if present, then add bonus modifiers and +15 if you made Flip 7. Check the 200-point target only after scoring the whole round; highest total wins. The linked rulebook does not specify a tied-score procedure, so agree a house tie-break before play if needed. Discard the round’s cards and pass the remaining deck left to the next dealer. Do not reshuffle every round. When the deck runs out, shuffle the discard pile; if this happens mid-round, leave every player’s current cards out of the shuffle.
Rules to double-check
- Reaching 200 during a turn does not stop the round. Flip 7 does.
- Action cards and modifiers do not count toward seven different numbers, and do not cause a number bust.
- ×2 does not double the +15 bonus or additive modifiers.
- Do not shuffle cards back each round or recycle cards still in front of players mid-round.
Player tips / 玩家建议
Beginner suggestions based on the rules, not guaranteed winning moves. DMs can share these with the whole table before play.
- Look at the numbers already exposed. High numbers have more copies in the deck, so a line containing many high numbers is risky.
- Protect a good round. Staying can be useful when you have strong points and no Second Chance.
- Count actual Number cards. Being close to seven may justify a risk, but modifiers do not bring you closer.
- Choose action targets carefully. Freeze can protect your own score or stop a rival from improving. Flip Three may help a rival as well as threaten them.
