How to Read Odds
Understanding odds is the most important skill in online betting. 688tk uses the decimal format, which is easy to follow.
Decimal Odds
You place a ৳500 bet at odds of 1.80. If you win, you get back: ৳500 × 1.80 = ৳900 (of which ৳400 is profit). The higher the odds, the larger the potential profit — but the chance of winning is generally lower.
Implied Probability
Odds of 1.80 mean the bookmaker estimates this team has roughly a 55.6% chance of winning. Formula: 1 ÷ 1.80 = 0.556, or 56%.
Comparing Other Formats
Fractional odds like 4/5 mean ৳4 profit for every ৳5 wagered. American odds like +150 mean ৳150 profit on a ৳100 bet, while -120 means you stake ৳120 to profit ৳100. Decimal is the most transparent format.
BPL Betting Guide
Betting on Bangladesh Premier League (BPL) and Bangladesh national team matches is hugely popular among cricket fans in Bangladesh. At 688tk, you can also place bets while a match is in progress.
Match Winner
Which of the two teams will win — the simplest and most popular betting market.
Top Batsman
Bet on which batsman from either team will score the most runs in the match.
Total Runs Over/Under
Whether the total runs scored will be more or less than a set number — for example, total runs in a Bangladesh vs India match.
Toss Betting
Bet on who will win the toss before the match begins — popular for quick results.

Crash Games — Aviator and More
Crash games are a new trend in online betting. Aviator by Spribe is the best-known name in this category.
How a Round Works
Place your bet before the plane takes off. The longer it flies, the higher the multiplier climbs. Cash out before it crashes and you keep your winnings. Wait too long and you lose everything.
Auto Cash Out
Set a specific multiplier in advance and the game will cash out automatically — no need to keep watching the screen.
Important: Set your own stop limit before playing crash games. No "signal" or "prediction" tool works — every round is determined completely independently.

What is a wagering requirement?
You must place bets at a specified multiple before withdrawing bonus money. Example: ৳1,000 bonus × 25 = you must place a total of ৳25,000 in bets to withdraw bonus winnings.
Game Contribution
Not all games contribute equally toward the wagering requirement. Slots generally contribute more, table games less. See the full terms for details.
Maximum bet while a bonus is active
There is a maximum limit on each bet while a bonus is active. Exceeding this limit may result in the bonus being cancelled.
Bonus expiry
Each bonus has a set time limit. If the wagering requirement is not completed within that time, the bonus will be cancelled.
Maximum cash out
There may be a maximum limit on how much you can withdraw from bonus winnings. Your account's real-money balance can be withdrawn without limit.
Bankroll Management Guide
Responsible play is not just about following rules — it is about protecting your money. Keep the following principles in mind.
Decide in advance how much you can spend each week or month. This amount should come from outside your essential living expenses.
Break your total budget into smaller sessions. Instead of spending it all at once, set a separate amount for each day or each game.
Try not to place more than 1 to 5 percent of your total session budget on a single bet. This helps you maintain your balance over the long term.
Set a target. Once you reach that amount, end the session and set your winnings aside — avoid betting everything again.
Stay calm after a losing streak. Placing bigger bets to recover losses — "chasing losses" — most often leads to even greater losses.
After each session, keep a record of your deposits, bets, and withdrawals. This will help you understand your own playing patterns and make adjustments when needed.
