Membership Benefits
VIP Benefits
Members in the oktk VIP program receive cashback on their net weekly losses. Higher tiers also come with special promotions, faster withdrawal processing and dedicated support. oktk VIP membership is evaluated automatically based on your regular play, so no separate application is needed.
oktk has four VIP tiers — Bronze (up to 0.4% weekly cashback), Silver (up to 0.8%), Gold (up to 1.1%) and Platinum (up to 1.5%). Cashback is calculated on the net loss for the week, which is total losses minus total winnings, at the rate for your tier.
Tier progression at oktk depends on the volume and consistency of your play. The more regularly you play, the faster you can move up. Specific turnover thresholds are not published, but you will be able to see your progress as you stay active.
Cashback is calculated on the net loss for the week. For example, a Gold tier member with a net weekly loss of ৳20,000 would receive ৳20,000 × 1.1% = ৳220 cashback. This amount is generally credited to the account the following week.
Yes, once VIP cashback is credited to your account it becomes part of your main balance. The minimum withdrawal amount is ৳1,000 and processing normally takes between 30 minutes and 3 hours. For full details on terms, visit the Terms and Conditions page.
Game Information
Slots and Jackpots
In a progressive jackpot, a portion of every bet is added to the prize pool, which keeps growing until someone wins it. Once won, the amount resets and starts building again. The odds of winning are lower, but the prizes can be very large. You can find various jackpot slots in the oktk Slots section.
Volatility measures how often a slot pays out and how large those payouts are. High volatility games pay out less frequently but the amounts tend to be larger. Low volatility games pay out more often but in smaller amounts. It is worth choosing volatility to match your budget and playing style.
RTP (Return to Player) is a game's theoretical return rate, calculated as an average across millions of spins over the long term. For example, Fortune Tiger has a maximum RTP of 96.81%. It does not guarantee winnings in any single session — every spin produces an independent, random result.
Many slot games have a demo mode that lets you try the game without using real money. Winnings in demo mode cannot be withdrawn. Trying a game in demo before playing for real is a sensible approach.
Low or mid volatility slots are more suitable for a limited budget because they allow longer play sessions. Choosing games with a high RTP, such as Fortune Mouse (maximum RTP 96.96%) or Mahjong Ways 2 (maximum RTP 96.95%), is a relatively sensible option. At oktk you can start playing with a minimum deposit of ৳100.
App and Browser
Playing on Mobile
Both the oktk Android (APK) and iOS apps are available through official channels. For full details about the app, visit the oktk App page or contact the site's 24/7 live chat support. You should not download the app from any third-party source.
If the connection drops, most games automatically pause at that point and resume from the same state once the connection is restored. If a spin was in progress when the connection was lost, the result is safe because it is recorded on the server side. If the problem persists, contact support.
If loading is slow, start by clearing the cache in the app or browser. On Android, go to Settings → Apps → oktk → Storage → Clear Cache. Try loading in private or incognito mode to see if that helps. Make sure your internet connection is stable, and reinstall the app if needed.
Yes, even without the app you can play all games on the oktk mobile-first website using Chrome or Safari on a smartphone. The interface automatically adjusts to fit a mobile screen. That said, using the app generally gives a faster experience.
Payment Methods
Deposits
Deposits are normally credited instantly. If the balance does not appear after a short wait, refresh the page and try logging out and back in at the oktk Login page. If the problem continues, contact live chat with proof of the deposit such as a screenshot or transaction number.
oktk currently accepts all popular payment methods in Bangladesh: bKash, Nagad, Rocket, Upay and bank transfer (for example Dutch-Bangla Bank, BRAC Bank). The minimum deposit amount is ৳100 for every method.
oktk does not charge any deposit fees itself. However, your payment provider — such as bKash or Nagad — may apply their own transaction charges under their own policies. It is best to check the relevant provider's website or app to confirm any such charges.
The minimum deposit at oktk is ৳100 and this applies to all payment methods. Your first deposit is eligible for a 150% bonus — for example, depositing ৳1,000 gives a bonus of ৳1,500, making the total balance ৳2,500 with a wagering requirement of ৳1,500 × 10 = ৳15,000.
To deposit with Nagad, log in to your oktk account and go to the Cashier section. Select the Nagad option, enter the amount and follow the instructions shown to complete the payment using the Nagad app or USSD code. Once successful, the balance will be added to your account immediately.
