KYC Guide — Verify Your Account
Know Your Customer (KYC) verification protects you and the platform. Here's everything you need to know before submitting your documents.
Why Is KYC Required?
KYC is a standard legal compliance process used by all regulated financial and gaming platforms worldwide. On 31bd, it serves two key purposes: (1) preventing underage gambling — all players must be 21 years or older, and (2) preventing fraud, money laundering, and identity theft. Verifying your account also ensures your withdrawals can be processed quickly without additional security checks.
Documents Required
- National ID (NID) — Front and back photo of your Bangladesh National ID card
- Address Proof — Utility bill, bank statement, or official letter showing your Dhaka or regional address (dated within 3 months)
- Selfie Verification — A clear photo of yourself holding your NID card next to your face
- Payment Method Proof — Screenshot or statement confirming the mobile wallet or bank account used for deposits
Processing Time
Standard KYC review takes 1–24 hours during business hours (BST, UTC+6). Submissions during peak hours may take slightly longer. You will receive an email notification once approved.
After Verification
Once verified, your account is fully unlocked: deposit and withdrawal limits are raised, faster withdrawal processing is enabled, and you gain access to VIP promotions and tournament entries.
Data Protection
All KYC documents are stored with 256-bit AES encryption. Your personal data is never sold or shared with third parties. See our Privacy Policy for full details.

Major Cricket Sponsorships in the Bangladesh Market
The online betting industry in Bangladesh has become deeply intertwined with professional cricket. Here's a look at how major operators engage with the cricket ecosystem.
Babu88 & Global T20 Leagues
Babu88 has been associated with franchise teams in the Global T20 Canada league, including the Montreal Tigers and Colombo Strikers, bringing brand visibility to the South Asian cricket audience.
Crickex & Regional Partnerships
Crickex has pursued regional cricket sponsorships across South Asia, aligning itself with domestic tournaments and national board events to build credibility in Bangladesh and India markets.
Jeetbuzz & Andre Russell
Jeetbuzz signed West Indies all-rounder Andre Russell as brand ambassador, a high-profile move that resonated strongly with Bangladesh cricket fans who follow the Caribbean Premier League and IPL.
BPL — Bangladesh Premier League
The Bangladesh Premier League is the premier T20 franchise tournament in Bangladesh. Online operators across the region run special promotions, enhanced odds, and player prop markets throughout the BPL season.
ICC & T20 World Cup Coverage
The ICC T20 World Cup draws the highest betting volumes in Bangladesh. Operators invest heavily in live markets, in-play streaming support, and bonus campaigns timed around Bangladesh Tigers fixtures.
IPL — Indian Premier League
IPL is massively popular among Bangladeshi cricket fans. The two-month season generates some of the highest betting traffic of the year, with markets covering every match, over, and player performance.
Slot Game Types Explained
New to online slots? Here's a breakdown of the main slot formats available at 31bd, so you can pick the right game for your style.
Classic Slots (3-Reel)
The original slot format — three reels, simple paylines, and straightforward gameplay. Great for beginners. Providers like NetEnt offer polished classic titles with clean mechanics.
Video Slots (5-Reel)
Five-reel slots with multiple paylines, bonus rounds, free spins, and rich visual themes. The most popular slot format globally. Pragmatic Play leads this category with titles like Gates of Olympus.
Progressive Jackpot Slots
A portion of every bet contributes to a growing jackpot pool. These can reach life-changing sums. Microgaming's Mega Moolah is the most famous example, with record multi-million payouts.
Megaways Slots
A proprietary reel mechanic by Big Time Gaming (BTG) featuring up to 117,649 ways to win per spin. The number of symbols on each reel changes randomly every spin, creating massive volatility and excitement.
Cascading Reels
Winning symbols disappear and new ones fall into place, potentially triggering chain wins from a single spin. NetEnt's Gonzo's Quest pioneered this mechanic, now widely adopted industry-wide.
Cluster Pays
Wins are formed by clusters of matching symbols rather than traditional paylines. Often combined with cascading reels for extended win sequences. Pragmatic Play and Play'n GO offer strong cluster pays titles.
RTP & House Edge Explained
Understanding these two core concepts will help you make smarter decisions about which games to play and how to manage your bankroll effectively.
What Is RTP (Return to Player)?
RTP stands for Return to Player and is expressed as a percentage. It represents the theoretical amount a game pays back to players over a very large number of spins or rounds. For example, a slot with 96% RTP will — in theory — return ৳96 for every ৳100 wagered over millions of spins. This is a long-run statistical average, not a per-session guarantee.
Always check a game's RTP in its paytable or rules section before playing. Most reputable providers like Pragmatic Play and NetEnt publish certified RTP figures for every title.
What Is House Edge?
The house edge is the mathematical complement of RTP — it represents the casino's average profit from each bet. A game with 96% RTP has a 4% house edge. Lower house edge means better long-term value for the player. Table games like blackjack (with optimal strategy) typically carry a house edge below 1%, while some slots can have edges of 5–8%.
Understanding house edge helps you choose games that align with your risk tolerance and session budget. It does not determine short-term outcomes — variance and volatility play a large role in individual sessions.
Volatility vs. RTP — Why Both Matter
Two games can share the same RTP but behave very differently. A high-volatility slot pays large wins infrequently, meaning you may go many spins without a significant return. A low-volatility slot pays smaller wins more regularly. For players with a limited session budget, low-to-medium volatility games offer more playing time per ৳100. High-volatility games suit players chasing large bonus rounds and are willing to absorb a longer dry spell. Always choose a game's volatility profile based on your personal risk comfort, not just its RTP number.

Betting Glossary for New Players
New to online betting? Here are 12 essential terms every player should understand before placing their first bet on 31bd.
The theoretical percentage of all wagered money a game returns to players over time. A 96% RTP means ৳96 back per ৳100 wagered on average across millions of rounds.
The casino's mathematical advantage over the player, expressed as a percentage. A 4% house edge means the casino expects to keep ৳4 per ৳100 wagered long-term.
The amount of money you place on a single bet. Your stake is the amount at risk — your winnings are calculated as a multiple of your stake based on the odds.
A numerical representation of the probability of an outcome and the payout you receive if correct. Decimal odds of 2.50 mean you win ৳2.50 for every ৳1 staked, including your original stake.
A bet type where you win or lose based on how far an outcome exceeds or falls below a bookmaker's quoted spread. Common in cricket (e.g., total runs markets).
A single bet combining multiple selections. All selections must win for the bet to pay out, but the combined odds are multiplied, offering much larger potential returns.
A bet placed on a sporting event while it is already in progress. Odds update in real time based on the current match situation — popular for BPL and T20 cricket matches.
A feature that lets you settle a bet before the event concludes, securing a partial win or cutting your losses. Available on selected sports markets at 31bd.
The total amount of money you have set aside specifically for gambling. Good bankroll management — never betting more than 1–5% of your bankroll per session — is key to responsible play.
In slots, volatility describes how frequently and how large wins occur. High volatility = rare but large wins. Low volatility = frequent but smaller wins. Choose based on your session budget.
A bonus round feature in slots that lets you spin the reels without using your own balance. Free spins are often awarded through scatter symbols or as part of welcome bonus packages.
A condition attached to bonuses specifying how many times the bonus amount must be wagered before withdrawal. A ৳1,000 bonus with 30x wagering requires ৳30,000 in bets before cashing out.
