Understanding Odds: Three Formats, One Meaning
tk3666 displays odds in three formats: Decimal, Fractional and American. All three express the same probability — only the way they are written differs. The example below makes this clear.
| Format | If Team A wins | Return on ৳500 stake |
|---|---|---|
| Decimal | 3.00 | ৳1,500 |
| Fractional | 2/1 | ৳1,000 profit + ৳500 stake |
| American | +200 | For the favourite: -125 means ৳900 on a ৳500 stake |
Example: Team B is priced at Decimal 1.80 (Fractional 4/5, American -125). A ৳500 stake returns ৳900 (profit ৳400). If the bet loses, the full ৳500 is gone.
Bet Slip: How to Place a Single Bet
Bet Slip — Example
Clicking on a market in any match adds it directly to the bet slip. Enter the stake amount in the stake field — the potential return is shown instantly. Press the "Place Bet" button to confirm the bet.
In the example above, Team A's odds were 3.00 and the stake was ৳500. A win returns ৳1,500 — that is ৳1,000 profit plus the stake back. A loss means the full ৳500 is gone. This simple calculation is the basis of a single bet.
Check the odds once more before placing a bet — odds change quickly in live betting. Keep your budget in mind when entering the stake. Following the responsible gaming guidelines keeps betting enjoyable.
Multi Bet: Three Selections Together
A multi bet combines selections from several matches. You only receive a return if every selection wins — one loss means the entire stake is gone. Because the odds are multiplied, the potential return can be much higher, but so is the risk.
3-Selection Multi Bet Calculation
Combined odds: 1.60 × 1.80 × 1.90 = 5.47 (approx.)
Stake ৳100 — if all win, return is ৳547
If even one loses, you lose the full ৳100.

Bet History: Open and Settled Bets
- Open Bets: Bets are shown here until the match ends. View the odds, stake and potential return at a glance.

- Withdraw: Once your balance builds up, withdraw a minimum of ৳1,000. Funds typically arrive within 15 minutes to 2 hours.
The "My Bets" or "Bet History" section of your tk3666 account shows a full list of all your bets. Each bet displays the match name, odds, stake and final result — win (✓ Won) or loss (✗ Lost) — clearly.
Odds on open bets may change during live betting. However, the odds at which the bet was confirmed are the ones used for the final settlement.
If you have any questions about rules or payment policy, read the Terms and Conditions page.
Before You Bet: Set a Budget and Limits
Betting is for entertainment — not as a source of income. Winning and losing are both a normal part of every bet. Set a weekly or monthly budget from the start that you can afford to lose without financial strain.
Set a Stake Limit
Use only a small portion of your total balance on each bet. Putting everything on a single bet is not a good idea.
Track Your Time
Avoid long, uninterrupted betting sessions. Taking breaks helps you stay clear-headed.
Do Not Chase Losses
Avoid placing larger bets in a hurry to recover a lost bet.
Responsible Gaming
tk3666 lets you set your own deposit limits. Read more on the responsible gaming page.
