Betting Glossary
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
The average percentage of total wagers that a game returns to players over the long term. For example, a 95% RTP means that on average ৳95 is returned for every ৳100 wagered.
House Edge
House Edge — the rate at which the casino profits in the long run from each game. It is the inverse of RTP.
Wager / Stake
The amount of money you place on a single bet is called a stake or wager. Always bet within your own means.
Odds
A mathematical expression of the probability of an event occurring. The higher the odds, the greater the potential payout, but the lower the chance of winning.
Parlay / Accumulator
Placing multiple match results together in a single bet. A big reward if all outcomes are correct, but the entire bet is lost if even one is wrong.
Live Bet (In-Play)
The ability to bet in real time while a match or game is in progress. Odds change every moment in line with how the game unfolds.
Bankroll
The total budget you set aside specifically for gaming. Experienced players always play with a defined bankroll.
Volatility
The frequency and size of wins in a slot game. High volatility means fewer but larger rewards; low volatility means frequent smaller wins.
Free Spins
The opportunity to spin for free in a slot game — usually given as a bonus. Wagering requirements apply to winnings from free spins.
Wagering Requirement
The condition specifying how many times you must wager the bonus amount before you can withdraw it. At fk3666 the welcome bonus wagering requirement is just 20x.
Cash Out
The ability to withdraw partial or full winnings in live betting before the game ends. An effective way to manage risk.
Spread Betting
Betting on the margin of points or goals rather than fixed odds. Win or loss is determined based on the difference in the outcome.

Bankroll Management Guide
The most important aspect of smart gaming is bankroll management — the key to enjoying yourself over the long term without financial stress.
- Set a budget: Decide in advance how much you can spend on gaming each week or month. Never exceed this limit.
- Divide into sessions: Split your total bankroll into smaller sessions. Instead of spending your entire budget in one session, set a fixed amount for each session.
- The 1–5% rule per bet: Never risk more than 5% of your total bankroll on a single bet. This ensures you can play for a longer time.
- Rule of stopping after a win: Make a habit of withdrawing a portion after a big win. Do not put all your winnings back into bets.
- Respect your loss limit: Stop when you have lost a set amount in a session. Come back the next day with a fresh mind.
Review your gaming history regularly. If your losses keep growing, take a break and seek support.
