RTP and House Edge Explained
RTP (Return to Player) is an overall statistical indicator for a game that shows what proportion of each bet players are likely to receive back over the long term. For example, if a game's RTP is 96%, there is an average chance of ৳96 coming back for every ৳100 wagered — however this is not guaranteed in a single session; it is the average result across billions of rounds.
House edge is the flip side of RTP — it is how much the casino retains on average from each bet. An RTP of 96% means a house edge of 4%. This rate differs across game categories: slots typically range from 92-98%, blackjack around 99%, and roulette from 94-97%.
Volatility refers to how frequently and how large a game's payouts are. High-volatility games pay out larger prizes less often; low-volatility games pay out smaller prizes more frequently. Choosing a game that suits your bankroll and play style is the smart approach.
Knowing RTP and house edge lets you choose games with awareness and keep your expectations realistic. All games at ctk66 are supplied by reputable providers — fair play is guaranteed.

Betting terms / glossary
Simple explanations of common betting and casino terms for new players.
RTP (Return to Player)
The statistical rate of how much of the total amount wagered on a game is returned to players over the long term. A higher RTP means more return in theory.
House Edge
The average share of each bet that the casino retains. It is the flip side of RTP.
Wager
The amount of money you are placing on a game or bet. To use a bonus, specific wagering requirements must be met.
Stake
The amount bet in a specific round or match. The higher the stake, the higher both the potential win and the potential loss.
Odds
A numerical way of expressing the probability of an event. The higher the odds, the less likely the event — but the bigger the reward if it wins.
Parlay / Accumulator
Combining multiple events into a single bet. All events must win, but the odds multiply together and the total reward can be very large.
Live Bet
A bet placed while a match or game is in progress. The odds change continuously as the situation develops.
Cashout
The option to withdraw a portion of your bet before the match ends. Even if a full win is not certain, this can help reduce losses.
Bankroll
The total amount of money set aside for playing. For responsible gaming, it is important to set a bankroll and stick to it.
Volatility
The frequency and size of rewards in a game. High volatility means large but rare rewards; low volatility means frequent but smaller rewards.
Free Spin
Spins received as a bonus in slot games at no cost. A chance to win without using your own balance.
Wagering Requirement
The condition specifying how many times a bonus must be wagered before the winnings can be withdrawn. At ctk66, the requirement is 25 times the bonus amount.
