| Bet Type | Example |
|---|---|
| Match Winner | Bangladesh vs India — Bangladesh to win |
| Toss Winner | Bangladesh to win the toss |
| Top Batsman | Which player will score the most runs |
| Total Runs Over/Under (O/U) | Will there be more than 150 runs in the innings |

How live in-play betting works
Odds change continuously while the match is in progress. When a wicket falls, the batting team's odds rise; after the powerplay, the bowling team's prospects shift. Total run odds also fluctuate over by over.
Live betting on T20 matches during the BPL and IPL seasons is especially exciting. At ok37 you get a live scorecard and real-time odds all in one place.
Crash Games — Aviator and More
The thrill of fast multiplier games
In crash games, each round lasts just a few seconds to a few minutes. The multiplier rises as the plane takes off — if you cash out before it crashes, your winnings are calculated using that multiplier.
Aviator by Spribe is the most popular crash game at ok37. With the Auto Cash Out feature, set a multiplier in advance — the game will cash out automatically once that level is reached.
Important safety advice
Set a stop limit for yourself before you start playing. No one can predict crash game outcomes in advance — do not trust any "signals" or "predictions". Play responsibly.

Betting Exchange
Back and Lay bets — bet directly against other players
In a regular sportsbook you bet against the site. In a betting exchange you bet against other players — the site only takes a small commission. This often means better odds.
| Back bet (standard bet) | Lay bet (opposing bet) |
|---|---|
| You are betting that the team will win | You are betting that the team will not win |
| If it wins: odds × stake amount | You are taking another player's bet |
| Simple and familiar to everyone | Liability is higher if you lose — pay attention |
Example (Back bet)
In the Bangladesh vs India match you Back Bangladesh with ৳500 at odds of 2.5. If Bangladesh wins you receive ৳1,250 (original ৳500 + winnings ৳750). If they lose you only lose ৳500. The exchange will deduct a small commission.
Account Verification Process
KYC — a simple and transparent process
KYC (Know Your Customer) verification is required for security and legal compliance. It confirms that the account belongs to the right person and that no unauthorised use is taking place.
National ID Card (NID)
Take clear photos of the front and back of your National ID Card. If the photos are blurry or incomplete you will need to resubmit them.
Proof of address
Submit a utility bill, bank statement, or any official government document that clearly shows your address.
Selfie verification
Take a selfie while holding your NID. Both your face and the card must be clearly visible.
Verification completed — 1 to 24 hours
After submitting your documents, verification is usually completed within 1 to 24 hours. Once successful, higher withdrawal limits are unlocked and your account stays protected.
