Stay when your number cards add up to about 25. With six different numbers in your row, push on until 35, because the 15-point Flip 7 bonus is worth the risk. Those two numbers come from working through the real 94-card deck, and they beat playing on gut feel.

How We Worked This Out
We shuffled the published Flip 7 deck 200,000 times in a simulation and dealt one player’s row card by card. The deck has one 0, one 1, two 2s and so on up to twelve 12s, plus 15 action and modifier cards (as listed in the rulebook). At every step we measured two things: the chance the next card busts you, and whether flipping again gains or loses points on average.
The numbers are for a fresh deck from one player’s view. Cards showing in other players’ rows lower your real risk a little, which the tips below use.
Your Bust Odds by Cards Held
| Different numbers in your row | Chance the next flip busts you (average) | Range, depending on which numbers |
|---|---|---|
| 1 | 7.8% | 0–12% |
| 2 | 15.5% | 0–24% |
| 3 | 23.1% | 1–35% |
| 4 | 30.6% | 5–45% |
| 5 | 37.9% | 8–54% |
| 6 | 45.1% | 17–62% |
The rule of thumb is about 7.5% more risk for every card you hold. The range matters as much as the average. A row of high numbers is far riskier than a row of low ones, because there are twelve 12s and only one 1.
Which Cards Are Risky to Hold
Each card in your row adds its own risk, based on how many copies are left. With about 88 cards left in the deck:
| Card in your row | Chance the next flip matches it |
|---|---|
| 12 | 12.5% |
| 10 | 10.2% |
| 8 | 8.0% |
| 6 | 5.7% |
| 4 | 3.4% |
| 2 | 1.1% |
| 1 or 0 | 0% (there’s only one) |
Add up the cards in your row to get your total bust chance. A row of 12, 11 and 10 is already about a third likely to bust on the next flip. A row of 1, 2 and 3 is under 4%.
The 25 Rule (35 With Six Cards)
Flipping is worth it when the points you expect to gain are bigger than the points you expect to lose by busting. Here’s where that flips over:
- Under 20 points: flipping again gains points on average in every situation we tested.
- 20 to 24: it depends on your cards. About a third of the time, flipping loses on average, mostly when you’re holding high numbers.
- 25 or more: flipping again loses points on average every time. Stay.
Six different numbers change the math. One more new number ends the round with a 15-point bonus, so flipping stays worth it up to a total of 34. At 35 and above it’s a loss nine times out of ten.
The ×2 card doubles what you’d lose by busting as well as what you’d gain, so stay a little earlier when you hold it. A Second Chance does the opposite: while you hold one, a duplicate can’t bust you, so keep flipping.
When to Break the Rule
The math assumes you just want the most points this round. Game position changes that:
- You’re far behind. Banking 22 points won’t catch the leader. Take bigger risks.
- You’re far ahead. Bank early and let others bust trying to catch you.
- Someone is near 200. If a rival will likely finish the game this round, your only job is to beat their total, not to play the averages.
Using the Other Rows
Cards in other players’ rows are out of the deck. If three 12s are already showing, your 12 is safer than the table above says. Before each flip, glance at what’s out for the numbers you hold.
Action cards are tactics too. Freeze banks the target’s points, so give it to someone with a small row, not a big one. Flip Three is best aimed at a player with a long row of high numbers, who is most likely to bust.

Frequently Asked Questions
When should you stay in Flip 7?
Stay when your number cards add up to about 25. Below 20, flipping again gains points on average; at 25 or more it loses points on average. With six different numbers, keep flipping until about 35 because of the 15-point Flip 7 bonus.
What are the odds of busting in Flip 7?
On a fresh deck, your next flip busts you about 8% of the time with one card in your row, 23% with three and 45% with six. High numbers raise the risk because the deck has more copies of them.
Which card is the riskiest to hold in Flip 7?
The 12. There are twelve of them, so each 12 in your row gives about a 12.5% chance that the next flip matches it. A 1 or a 0 can never be matched because each appears only once.
Is Flip 7 all luck?
Mostly, but not entirely. Knowing when to stay and who to target with action cards gives a steady edge over a full game to 200, even though any single round can go wrong.
