RTP & House Edge Explained
RTP, or Return to Player, is the percentage of all wagered money that a casino game pays back to players over time. For example, a slot with 96% RTP theoretically returns ৳96 for every ৳100 wagered across thousands of spins. It is a long-run statistical average, not a guarantee for any single session.
House edge is simply the inverse of RTP — it represents the casino's mathematical advantage. A game with 97% RTP has a 3% house edge. Lower house edge means better long-term value for the player. Knowing these numbers before you play helps you choose games that match your risk appetite.
| Game Type | Typical RTP Range | House Edge |
|---|---|---|
| Slots | 92% – 98% | 2% – 8% |
| Blackjack (Basic Strategy) | ~99% | ~0.5% |
| Roulette (European) | 94% – 97% | 2.7% – 5.3% |
| Baccarat (Banker Bet) | ~98.9% | ~1.1% |
| Video Poker | 96% – 99% | 1% – 4% |
Volatility is another key concept: high-volatility slots pay less frequently but in larger amounts, while low-volatility slots deliver smaller, more regular wins. Choosing between high and low volatility depends on your session budget and how long you want your bankroll to last.
Always check the paytable and published RTP before starting a new game. Responsible players use this information as a planning tool, not as a prediction of results. atk11 displays RTP information transparently for all listed games.
Betting Glossary
Return to Player — the percentage of total bets a game returns to players over a statistically significant number of rounds. Higher is better for the player.
The mathematical advantage the casino holds over players in any given game, expressed as a percentage of each bet. Lower house edge games return more value to the player over time.
The amount of money placed on a single bet. In sports betting this is called a stake; in casino games it is often called a wager or bet amount.
A numerical expression of the probability of an outcome. In decimal odds (used on atk11), 2.00 means a winning ৳100 bet returns ৳200 total (৳100 profit). Higher odds indicate a less likely outcome with a bigger potential payout.
A single bet combining two or more selections. All selections must win for the bet to pay out. The odds multiply across legs, creating higher potential returns but lower probability of winning.
A bet placed on a sporting event after it has already started. Odds update in real time based on the match situation. atk11 offers live betting on BPL, IPL, T20, and football matches.
A feature allowing you to settle a bet before the event finishes, locking in a profit or cutting a potential loss. The cash-out value fluctuates based on current match odds.
The total amount of money a player has set aside specifically for betting or gambling. Managing your bankroll — only risking a small percentage per bet — is the foundation of responsible gaming.
A measure of how often and how much a slot or game pays out. High volatility means infrequent but large wins; low volatility means frequent but smaller wins. Neither is inherently better — it depends on your playing style.
A bonus slot spin awarded at no extra cost to the player, either as part of an in-game feature (scatter trigger) or as a promotional bonus. Free spins winnings are usually subject to a wagering requirement before withdrawal.
A condition attached to a bonus that requires players to bet the bonus amount (or bonus + deposit) a specified number of times before winnings can be withdrawn. For example, a 20x wagering requirement on a ৳1,000 bonus means betting ৳20,000 in total before withdrawing.
