What Are RTP & Volatility?
Why Your Choice of Game Matters
Ever wonder why some slots behave differently? It's not luck—it's math. Learn the two secret numbers that define every slot game: RTP and Volatility.
When you open a game on Bigwin959, whether it's from JILI, Pragmatic Play, or PG Soft, you are interacting with complex math. Many beginners pick games just by the picture or theme.
This is a mistake. To play smarter, you need to look at the engine under the hood. That engine is built on two concepts: RTP (Return to Player) and Volatility (Risk).
What is RTP?
Return to Player
RTP is the theoretical percentage of all wagered money that a slot pays back to players over time.
The Golden Example:
If a game has an RTP of 96%: For every 100 BDT bet by players, the game is programmed to return 96 BDT as winnings (to someone, eventually) and keep 4 BDT as profit (House Edge).
Good RTP
96% - 98%
Look for these numbers.
Bad RTP
Below 94%
Avoid these tailored for land-based casinos.
*Note: RTP is calculated over millions of spins. It does NOT guarantee you will win back 96 BDT for every 100 BDT you bet in a short session. Short term is luck; long term is math.
What is Volatility?
Risk Level / Variance
Volatility defines how often you win and how big the wins are. It is the "personality" of the slot.
Low Volatility
Pays out frequently, but wins are usually small.
Best for: Relaxed play, small bankroll.
Example: Starburst, Classic Slots.
Medium Volatility
A balance. Mixed wins of all sizes. Moderate risk.
Best for: Most average players.
Example: Gonzo's Quest, JILI Golden Empire.
High Volatility
Pays out rarely, but wins can be massive.
Best for: Jackpot hunters, big budgets.
Example: Gates of Olympus, Bonanza.
How to Check the RTP?
Find the hidden number
Game providers are required by law to show the RTP inside the game. Here is how to find it on Bigwin959:
- 1
Open the game (e.g., Gates of Olympus).
- 2
Look for the "i" (Information) icon or a "Settings" gear icon.
- 3
Scroll down the text. You will find a sentence like: "The theoretical RTP of this game is 96.50%".
Which Slot Should You Play?
The "best" game depends on your bankroll and goal. Here is a cheat sheet:
"I have a small budget (500-1000 BDT) and want to play for a long time."
Choose Low Volatility games. They keep your balance steady.
"I want to win big, and I don't mind losing fast if I don't hit."
Choose High Volatility games (e.g., Gates of Olympus). You might lose 10 spins in a row, but the 11th could be huge.
"I want the scientifically best odds."
Always check the info page and choose the game with the Highest RTP (97%+).
RTP & Volatility FAQs
Can RTP change?
Some games have adjustable RTP ranges. Bigwin959 always selects the standard certified RTP version from providers (e.g., Pragmatic Play default). Always check the info inside the game.
Is high volatility better for bonuses?
Generally, yes. High volatility slots often have harder-to-trigger bonuses, but when they do trigger, the payouts can be massive (5000x+).
Does the previous spin affect the next one?
No. Every spin is independent. Even if a jackpot just hit, it can hit again on the very next spin. This is called RNG (Random Number Generator).
