Most hands are for waiting

The app tells you when there is nothing to do.

At the start of a shoe every bet is negative, and most hands stay that way. Instead of making you guess, the calculate screen says it plainly: no bet crossed the line, sit this hand out.

Patience MeterWhere you are in the shoe, and where positive spots usually show up. In the app's own simulation: about 11 positive spots per shoe, mostly after card 312, each lasting about 4 hands.
Shoe ReplayAfter a shoe ends, see which hands had a positive bet and how long the wait was.
Why this mattersPositive spots are rare and short. Knowing that in advance is what makes waiting bearable.

Reading one number

+10.5

Panda: for every 100 wagered, 10.5 back on average over the long run.

It comes from the cards left, not a prediction. The next hand can still lose, and a few hands later it may be negative again.

What Baccarator will not do

It does not predict the next hand. A positive EV is a long-run average, and any single hand can lose.

The odds come from a Monte Carlo simulation of the remaining cards: 1,000,000 deals per calculation. They are close estimates, not exact values.

There is no real-money gaming in the app. It is a math and education tool for adults 18 and over.

Many venues ban phones or decision aids at the table. Always follow local law and house rules.

Questions

What does Baccarator do?

You enter the cards from each hand and tap Calculate. The app works out which cards are left in the shoe and recalculates the probability and expected value of Banker, Player, Tie and the side bets.

What is a positive EV moment?

Some side bets are sensitive to the remaining cards. Deep in a shoe their expected value can briefly rise above zero. These moments are rare and short, and a positive EV is still a long-run average.

Will Baccarator help me win?

No tool can guarantee wins. Every main bet carries a house edge, and any single hand can lose. The app shows the numbers; what you do with them is your decision.

Is Baccarator free?

The download is free and includes the core probability features. A monthly membership unlocks side bet tracking, the Kelly ratio and advanced statistics.

Where can I use it?

Anywhere you can see the deal: studying shoes, practice, or reviewing a session. Many venues ban phones and decision aids, so always follow local law and house rules. The app contains no real-money gaming.
