RTP and House Edge Explained
What is RTP (Return to Player)?
RTP is the long-term theoretical return rate of a game, expressed as a percentage. For example, if a game has an RTP of 96%, then theoretically there is an average chance of ৳96 being returned for every ৳100 wagered. This is an average across millions of rounds — results in a single session can be completely different.
Typical RTP Ranges Across Different Games
Slot games generally have an RTP between 92% and 98% — this varies by provider and title. Table games such as blackjack can offer an RTP close to 99% when played with the correct strategy. European Roulette typically has an RTP between 94% and 97%, while the American variant is comparatively lower. The RTP of crash and arcade games varies depending on the developer and settings.
What is House Edge?
House edge is 100 minus the RTP — meaning this is the percentage by which the game favours the casino over the long term. An RTP of 96% means a house edge of 4%. This is not a guarantee — every spin or hand is completely independent and random.
Why Is It Important to Know This?
Understanding RTP and house edge makes you a more informed player. Choosing games with a higher RTP and playing within your own budget — these two habits are the core foundation of responsible gaming. No strategy or system can bring the house edge down to zero.
How to Read Odds
Decimal Odds
The simplest format. Example: you place a ৳500 bet at odds of 1.80.
Total return = ৳500 × 1.80 = ৳900
That means a profit of ৳400.
Implied Probability
Work out the probability of winning from the odds:
1 ÷ 1.80 × 100 = 55.6%
According to the bookmaker, the probability of this event winning is 55.6%.
Other Formats
Fractional (4/5): British style, less common.
American (+/−): seen on US sites.
18coi uses the decimal format — easier for Bangladeshi players.
Football Betting
Bangladeshi fans regularly follow the Premier League, La Liga, UEFA Champions League, and FIFA World Cup qualifiers. Many big matches kick off at midnight Bangladesh time or later — so the live betting feature is especially useful.

Beware of Fake Sites and Scams
Identify the Official Site
Always make sure the address bar shows 18coi.cam and that there is a secure HTTPS connection. If the spelling differs or there is a subdomain, it is a fake site.
Do Not Share Your OTP or PIN
Our support representatives will never ask for your bKash/Nagad PIN or SMS OTP. If anyone asks for this, it is a scam.
Avoid Telegram / Facebook Links
Be careful of people who contact you posing as an "agent". Fake APK files can steal information from your phone.
What to Do If You Are Scammed
Change your password immediately, update your bKash/Nagad PIN, and notify us via live chat. The sooner you let us know, the sooner we can help.
