How weekly cashback works
Each week, your net loss is calculated by subtracting your total winnings from your total losses. Based on your VIP level, a set percentage of that net loss is returned to your account every week.
Calculation example (Gold member):
This is the maximum cashback payable at that tier.
Cashback softens the impact of a big loss — but it should not be treated as a way to win.

Local card games
Card games familiar in Bangladesh are now available to play online.
Teen Patti
Each player receives three cards and the player with the highest hand wins the patti. Play with a live dealer or at a multiplayer table. Starting tip: begin with small bets to get a feel for the hand, then increase.
Andar Bahar
One card is placed in the middle; players bet on whether a matching card will appear on the left side (Andar) or the right side (Bahar) first. Played with a live dealer. Simple for newcomers — only two choices.
Callbreak
A trick-taking game for four players — before each round you declare how many tricks you will win, then you must meet that number. Direct competition against other players. Tip: Spade cards always act as trump.
Ludo and Rummy
The familiar game of Ludo is now available in a fast online format — against other players. Rummy calls for skill in matching sets and sequences. Both are played in multiplayer format against other users.

Common myths vs facts
Some common misconceptions about online gaming and their straightforward explanations.
"If a slot hasn't paid out in a long time, it must be due for a win soon."
FactEvery spin is completely independent. Previous results have no effect on the next spin — this is the core principle of RNG (Random Number Generator).
"A losing streak means the next bet is guaranteed to win."
FactThe house edge stays the same every round. Previous losses do not increase the chances of winning in the next round — each outcome is determined fresh.
"There is a guaranteed winning system in Baccarat."
FactNo betting system can eliminate the house edge over the long term. Martingale or any other method still carries the risk of a continuous losing streak.
"Depositing more increases your chances of winning."
FactA larger deposit allows for bigger bets, but the win rate on each bet stays the same — bigger bets also mean bigger risk.
"Slots pay out more at night."
FactSlot RTP does not change with the time of day. The server-based RNG works the same way on every spin.
"It is easier to win with a new account."
FactAccount age does not affect game outcomes. RTP is the same for everyone — whether the account is new or old.
Betting is entertainment — for adults aged 21 and over. Never play beyond your budget.

Bonus Terms Explained
Learn what these terms mean before claiming a bonus for the first time — so there is no confusion later.
You must bet a certain number of times before you can withdraw bonus money — this condition is called wagering. On the tk688 welcome bonus, the bonus amount must be wagered 10 times. Example: on a ৳1,000 deposit you receive a ৳2,000 bonus, making the total balance ৳3,000, and you must wager ৳2,000 × 10 = ৳20,000.
The maximum amount you can place on a single bet while a bonus is active. Exceeding this limit may result in the bonus being cancelled. Check the site's T&C for the specific amount before claiming a bonus.
Not all games contribute equally toward wagering. Slots generally contribute 100%, but live casino and other games may contribute less. Read the T&C to find out which games are most effective to play.
Every bonus has a set expiry period. If the wagering requirement is not completed within that period, the bonus and any winnings from it are cancelled. The countdown starts as soon as the bonus is claimed.
With a non-sticky bonus, once wagering is complete the bonus balance is removed and only the actual winnings remain. With a sticky bonus, the bonus balance stays throughout but cannot be withdrawn directly — it can only be used for playing.
Some bonuses set a maximum amount that can be withdrawn after wagering is complete. Even if you win more than that limit, only the capped amount can be withdrawn — so find out in advance.
