RTP & House Edge Explained
Return to Player (RTP) is a percentage that represents how much of all wagered money a game is theoretically expected to pay back to players over a very large number of rounds. For example, a slot with a 96% RTP will, over time, return ৳96 for every ৳100 wagered — the remaining ৳4 is the house edge. RTP is a long-term statistical measure, not a guarantee of what any individual session will return.
House Edge is simply the inverse of RTP — it is the mathematical advantage the casino holds on each game. A blackjack game with a 99.5% RTP has a house edge of just 0.5%, meaning it is one of the most player-friendly games available. Understanding house edge lets you choose games that align with your risk tolerance and budget.
Volatility (or variance) describes how a game pays out. Low-volatility games pay smaller amounts more frequently; high-volatility games pay larger amounts less frequently. RTP alone doesn't tell the full story — a 96% RTP slot can play very differently depending on whether it is low, medium, or high volatility.
At 399db, all game RTPs are verified by the provider and available in each game's help/info section. We encourage every player to review these figures before playing, particularly when managing a limited session budget.
Typical RTP Ranges by Game Type
| Game Type | RTP Range | House Edge |
|---|---|---|
| Video Slots | 92% – 98% | 2% – 8% |
| Classic Blackjack | ~99.5% | ~0.5% |
| European Roulette | ~97.3% | ~2.7% |
| American Roulette | ~94.7% | ~5.3% |
| Baccarat | ~98.9% | ~1.1% |
| Live Casino Tables | 95% – 99% | 1% – 5% |
| Crash Games | 95% – 97% | 3% – 5% |
* RTP figures are theoretical long-run averages. Actual session results will vary. Always play within your means.
Cricket Formats Explained
Understanding the difference between T20, ODI, Test and The Hundred helps you pick the right betting markets and make more informed wagers on your favourite matches.
Twenty20 (T20)
Each team faces 20 overs (120 balls). A typical match lasts 3–3.5 hours. The shortest and most explosive format, with the widest range of in-play betting markets — sixes, wickets, top batsman, match winner, and over-by-over totals.
One Day International
Each team bats for 50 overs, with a match lasting roughly 8 hours. ODIs offer a fuller range of session betting and player performance markets. Bangladesh Tigers have a strong ODI record, making these matches particularly popular on 399db.
Test Cricket
The longest format — up to 5 days, unlimited overs. Test betting focuses on session results, day-by-day outcomes, and first innings leads. Fewer in-play markets than T20 but higher-stakes outcomes and longer odds windows.
The Hundred
100 balls per side, originating in England. Matches last around 2.5 hours. A newer format gaining traction globally, with fast-paced betting markets similar to T20 but with unique over structures that create fresh wagering opportunities.
