Live DealerCallbreak Quick
4 players use a 52-card deck and try to win tricks. You bid at the start of each round and the goal is to win exactly that many tricks. Tip: Spades are always trump — count the spades in your hand before placing your bid. JILI's Callbreak Quick is played against other players.

Betting Glossary
Simple definitions of key betting and casino terms for new players.
RTP (Return to Player)
A theoretical calculation of the percentage a game returns to players over the long term. For example, a 96% RTP means there is an average chance of getting back ৳96 for every ৳100 wagered.
House Edge
The mathematical advantage built into every game in favour of the casino or betting site. It is the opposite of RTP — where RTP is 96%, the house edge is 4%.
Wagering Requirement
The number of times a bonus amount must be wagered before it can be withdrawn. The wagering requirement for the welcome bonus at 123mkb is just 10x.
Volatility
A measure of how risky a slot or game is. High volatility means less frequent wins but larger rewards; low volatility means more frequent wins but smaller amounts.
Free Spin
The chance to spin the slot reels without spending your own money. Available as part of bonus offers or as an in-game feature.
Odds
In betting, the ratio representing the probability of an event occurring and how much you will receive if you win. The higher the odds, the greater the risk — but the reward is also higher if you win.
Accumulator / Parlay
A single bet placed on multiple matches or events at once, where all predictions must be correct to win a large reward. If even one is wrong, the entire bet is lost.
Live Bet
The ability to place bets in real time while a match is in progress. BPL and IPL matches at 123mkb allow ball-by-ball live betting.
Bankroll
The total amount of money set aside specifically for gambling. Good bankroll management means placing only a small portion of the total amount on each bet.
Cashout
The option to withdraw a portion of your bet before a match ends. This lets you secure a partial profit before losing the entire bet.
Spread
An imaginary points difference between two teams set by the bookmaker. In spread betting, the margin of victory matters, not just who wins or loses.
Stake
The amount of money you place on a specific bet is called the stake. Your potential winnings are calculated based on the stake.

123mkb's skilled support team is always ready to help with any issue you have. Even if something goes wrong at 3 in the morning, we are here.
