Player Education
RTP & House Edge Explained
Return to Player (RTP) is a percentage that represents the theoretical amount a game pays back to players over a very large number of rounds. For example, a slot with a 96% RTP will, on average, return ৳96 for every ৳100 wagered over millions of spins. RTP is a long-run statistical figure — it does not predict your individual session outcome.
House Edge is simply the inverse of RTP — it represents the mathematical advantage the casino holds over time. A game with 96% RTP has a 4% house edge. Understanding this helps you make informed choices about which games to play and how long your bankroll is likely to last.
Volatility (also called variance) describes how frequently and how large a game pays out. High-volatility slots pay out less often but can deliver larger wins. Low-volatility games pay smaller amounts more frequently. Your choice should match your playing style and available bankroll.
At si6s, all game RTPs are verified by independent testing laboratories and published transparently in each game's information panel. We encourage every player to review the RTP before playing — it is one of the most important pieces of information available to you as a bettor.
* RTP figures are theoretical averages across millions of rounds and are provided for educational purposes. Actual results will vary. Always check the specific game's information panel for its certified RTP value.
Transparent & Secure
Account Verification & KYC Guide
Know Your Customer (KYC) verification is a standard security and legal compliance requirement across all regulated online betting platforms. At si6s, KYC protects both you and the platform — preventing fraud, ensuring payouts go to the rightful account holder, and keeping underage individuals away from gambling services.
The process is straightforward and typically completed within 1–24 hours. Once verified, you enjoy unrestricted access to all withdrawal methods and higher transaction limits.
Submit Your National ID (NID)
Upload a clear photo or scan of your Bangladesh National Identity Card (NID) — both front and back. The name on your NID must match the name on your si6s account exactly.
Proof of Address
Provide a recent utility bill, bank statement, or official document showing your current residential address in Bangladesh. The document must be dated within the last 3 months.
Selfie Verification
Take a clear selfie holding your NID next to your face in good lighting. This confirms that you are the genuine owner of the identity documents submitted.
Review & Approval (1–24 Hours)
Our compliance team reviews your documents, typically within 1–24 hours. You will receive an in-app notification and email confirmation once your account is fully verified.
Full Access Unlocked
After verification you can withdraw to any registered bKash, Nagad or Rocket account instantly, with no additional delays or documentation requirements for standard transactions.
Know the Terms
Betting Glossary
New to online betting? Here are 12 key terms every si6s player should know before placing their first wager.
- RTP (Return to Player)
- The theoretical percentage of all wagered money that a game pays back to players over time. A slot with 96% RTP returns ৳96 per ৳100 wagered on average across millions of spins.
- House Edge
- The mathematical advantage the casino holds over the player, expressed as a percentage. It is the complement of RTP — a 96% RTP game has a 4% house edge.
- Wager / Stake
- The amount of money you risk on a single bet. In Bangladesh, stakes are denominated in Taka (৳). Always wager only what you can comfortably afford to lose.
- Odds
- A numerical representation of the probability of an outcome and the potential payout. Decimal odds of 2.00 mean a winning ৳100 bet returns ৳200 total (৳100 profit).
- Spread
- A points handicap applied to a team to level the betting field. Commonly used in cricket and football — the favourite must win by more than the spread for that bet to pay out.
- Parlay / Accumulator
- A single bet combining multiple selections. All selections must win for the bet to pay out, but the combined odds — and potential payout — are significantly higher than individual bets.
- Live Bet (In-Play)
- A bet placed on a sporting event after it has already started. Odds update in real time based on the match situation — popular for cricket, where momentum shifts frequently.
- Cash Out
- A feature that lets you settle a bet early — before the event ends — for a partial return. Useful for locking in profit or cutting losses if the match turns against you.
- Bankroll
- The total amount of money you have set aside specifically for betting. Effective bankroll management — never risking more than 2–5% per bet — is key to long-term responsible play.
- Volatility
- Describes how often and how large a slot game pays out. High-volatility games pay less frequently but can award larger wins; low-volatility games pay smaller amounts more often.
- Free Spin
- A bonus feature in slot games that allows a set number of spins without deducting from your balance. Often triggered by scatter symbols or awarded as part of a promotional bonus.
- Wagering Requirement
- A condition attached to bonuses specifying how many times the bonus amount must be bet before winnings can be withdrawn. Example: a ৳1,000 bonus with 20x wagering requires ৳20,000 in total bets.
