RTP, Volatility and House Edge: Casino Terms Explained

Three terms appear on almost every casino game screen: RTP, volatility and house edge. They are easy to misread. Here is what each one means and what it does not mean.

RTP: Return to Player

RTP is the percentage of all money wagered that a game is designed to pay back to players over a very long run. A slot with a 96% RTP returns, on average, ₱96 for every ₱100 wagered across millions of spins. The other ₱4 is the operator’s margin.

House Edge: the Other Side of RTP

House edge is simply 100% minus the RTP. If a game has a 96% RTP, the house edge is 4%. Table games are usually described by their house edge. For example, a European roulette wheel with a single zero has a house edge of about 2.70%, while an American wheel with a double zero has about 5.26%.

Baccarat, Tie betAbout 14.36%Eight decks, 8 to 1 payout
Blackjack with basic strategyAround 0.5%Common rules, varies by table

Volatility: How Bumpy the Ride Is

Volatility, sometimes called variance, describes how widely results swing. Low-volatility games pay small amounts frequently. High-volatility games pay less often, but individual payouts can be larger. Two games with the same RTP can feel completely different.

How the Three Fit Together

  • RTP and house edge describe the long-run average cost of playing.
  • Volatility describes how much your balance may move in the short run.
  • A low house edge does not guarantee a profitable session, and a high-volatility game does not make winning “due”.

How to Read a Game’s Information Panel

  1. Step 1

    Open the game’s info or rules page

    Look for an “i” or help icon inside the game.

  2. Step 2

    Find the stated RTP

    If the game does not show it, check the operator’s game information pages.

  3. Step 3

    Check the bet rules and limits

    Note the minimum and maximum bets and how each type of bet pays.

  4. Step 4

    Look at the volatility label

    It may say low, medium or high. Pick the style that fits your budget.

  5. Step 5

    Decide your stop point before you start

    Choose a spend limit and a time limit, then stick to them.

Conclusion

The house edge figures in this article are calculated from standard game rules and will differ if a table uses other rules. RTP and house edge tell you the average cost of a game. Volatility tells you how uneven the ride might be. None of them lets you predict a single outcome. For the broader picture, see our games guide, and read the responsible gaming page before you play.

Frequently asked questions

Is a higher RTP always better?

A higher RTP means a lower average cost per wager, but it does not guarantee a win in any session.

Why do two slots with the same RTP feel different?

Because of volatility. One may pay small prizes often, and the other may pay rarely but in larger amounts.

Can I find a game’s RTP?

Many licensed operators show it in the game’s info screen or in the game provider’s documentation.
