Vegas has no governing body and no rulebook. Every group plays a slightly different version, which is fine — right up until two people find out they disagreed, on the eleventh hole, for money. So the first job isn’t learning the rules — it’s knowing which version you’re playing.
Everything else in Vegas is a variation on this. Four players split into two teams of two. On each hole, both players on a team hole out, and their two scores are combined into a single two-digit number — the lower score first. A 4 and a 5 is 45, not 54. A 3 and a 6 is 36.
Then the two teams compare numbers. The lower number wins, and the difference between them is the points that change hands. That's the whole game: one subtraction per hole.
The reason it gets a reputation is that the difference can be enormous. A team with a 4 and a 5 has 45. A team with a 5 and a 7 has 57. That's 12 points on one hole — and Vegas is normally played for a set amount per point, so a couple of bad holes moves real money.
Nobody picks up. Every player needs a score, because both count.
Your 4 and 5 becomes 45. Their 5 and 7 becomes 57. This is the rule people get backwards — it's always the lower score in the tens column, never the order you finished in.
Your team wins 12 points. At 25¢ a point that's $3 on the hole; at $1 a point it's $12.
The calculator on the home page is a live hole. Change any score and watch the numbers move, including the flips and doubles below — it's faster than any explanation on this page.
The core above is nearly universal. These four are where groups differ most, and each one can swing a hole by twenty points or more. Big Baller Vegas applies all four the same way every round — all of them are listed below.
If anyone on your team makes a birdie, the opposing team's two digits swap. Their 57 becomes 75, and a hole you were winning by 12 you're now winning by 30. This is the single biggest mechanic in the game — the flip is worth more than most good shots.
If both teams make a birdie on the same hole, the numbers stay in their original order. The birdies offset. Same for two eagles. But only equal efforts cancel — a birdie does not neutralise an eagle. Worth confirming before you play — some groups flip both instead, which produces a completely different result.
An eagle flips the opponents' number and then doubles the whole difference — and two natural birdies on the same team does the same thing. This is where a hole becomes a round: a 30-point win becomes 60. Matching strength still cancels, so an eagle against an eagle is a wash, but a birdie does not cancel an eagle — the stronger effort wins.
Nothing runs away from you. No score counts for more than net double bogey, so one wrecked hole can’t decide the round — and that’s what lets a 20-handicap play the same game as a scratch without getting buried. Some groups play uncapped, where a single hole can cost a fortune; we may offer that later for groups who want the extra risk.
The traditional game uses raw scores and no handicaps, which works if everyone plays to a similar standard. In a group spanning a scratch player and a 20, it doesn't — the low handicap wins every hole and the game is over by the fourth.
So most groups play net: apply handicap strokes, then build the two-digit number from the net scores. That's what we do, and it's what makes a mixed group competitive.
Standard allocation off the card's stroke index — nothing invented. Your course handicap tells you how many strokes you get; they fall on the hardest holes first, one per hole, in stroke-index order.
A flip needs a real birdie, not a net one off a handicap stroke. Otherwise the highest handicap in the group flips the most holes, which isn't what anyone means by a birdie.
Course handicaps for nine holes use the nine-hole rating and slope — not half the 18-hole figure, which gives the wrong answer. A detail most apps get wrong and every handicap committee cares about.
Indexes change daily, and a stale one moves everyone's strokes — which moves the money. We ask each player to confirm their current index at setup rather than storing one and hoping.
Vegas is a partner game, so it needs two teams of two. If someone cancels, the traditional answer is that you don't play Vegas — which is why most groups end up playing something duller instead.
Our answer is Lucky and Chance — two players who stand in when you're short. Other golf apps use the word "ghost" for playing against your own past round; this is a different thing: a fill-in partner, so the game still happens.
Lucky and Chance have nothing to win — whatever they score folds into their partner’s side. A player with no stake doesn’t need a handicap, so they play off the lowest handicap index in the group and take no strokes while everyone else gets shots. Beating one means something.
The full round is drawn at setup, sealed, then revealed hole by hole as scores are saved. They can’t see how you’re playing and can’t react to it, and nothing can be adjusted mid-round by anyone.
Most simulated opponents shoot their average every hole, which is why they feel fake. They draw a realistic round for that index and spread it the way real rounds fall — some birdies, mostly pars, the occasional blow-up.
A par 5 is a scoring chance and they birdie them at roughly the rate a real player of that standard does. A par 3 isn’t, and they don’t. That’s the difference between a simulated round and a shuffled one.
Lucky is streaky — more birdies, more trouble. Chance grinds it out. Same scoring average, completely different rounds, and the app tells you which one you’ve got before you start.
Two humans means you each have a stand-in, so you’re covering their action as well as your own — every point is worth double to you. The app says so before you agree to a stake, not after.
Since there is no official Vegas, the honest thing is to publish exactly what this app scores — every round, the same way.
| Rule | How it works |
|---|---|
| The number | Low ball first, always. A 4 and a 5 is 45. |
| Handicaps | Net scores, standard stroke-index allocation — so mixed handicaps play the same game. |
| Birdie flip | A natural birdie flips the opponents’ number. Handicap strokes don’t earn a flip. |
| Matching efforts | Equal efforts cancel — birdie against birdie, eagle against eagle. A birdie does not cancel an eagle. |
| Eagles | Flip and double the hole. Two natural birdies on a team does the same. |
| Blow-ups | Capped at net double bogey. One hole can’t decide the round. |
| Partners | Fixed all day, 6-6-6 (changing every six holes), or Left/Right (redrawn every hole off the tee). |
| Short groups | Lucky and Chance stand in — off the low index, no strokes, no stake. |
Most groups play Vegas somewhere between 10¢ and 25¢ a point. That sounds small, and then a flipped-and-doubled hole arrives and you find out why the game is called what it's called.
At 25¢ a point, a typical four-player round moves roughly $11 per player, with a rough day closer to $28. At $1 a point those become about $43 and $110. And in a two-player game where you each have a stand-in, double both figures — that's the case that surprises people.
The app shows the measured swing for your group next to the stake you're choosing, before anyone agrees to anything. We'd rather you picked a number you're comfortable with than found out on the ninth green.
Capping at net double bogey is what keeps the figures above honest. Without it, one wrecked hole can dwarf a whole round — which is fun for nobody and hardest on the highest handicap in the group. Pick a stake for the round you’ll actually play, not for a disaster that can’t happen.
No — Big Baller Vegas is a scorekeeper. It works out the points and what they're worth for a game you and your friends already agreed to play, the same way a pencil and a scorecard would.
No money moves through this app. We don't process payments, hold funds, take a cut, or facilitate any transaction. We are not a payment processor, not a gambling operator, and not a party to any wager between players. If you settle up with Venmo, Zelle or cash, that happens directly between you and the people you played with. We only ever show you the number.
There's no house here. No odds, no rake, no pot. Whatever changes hands is between four people who chose to play together, and settling up is theirs to do.
Every hole shows exactly how it was scored — the strokes, the flip, the double, the difference — so the rules on this page never have to be argued about again.
