Important Notice: By accessing, registering on, or using any part of the sona1 platform at sona1.bio, you confirm that you have read, understood, and agree to be legally bound by these Terms & Conditions in their entirety. If you do not agree with any part of these Terms, you must not use the sona1 platform. These Terms were last updated in January 2026 and supersede all previous versions.
1. Acceptance of Terms
These Terms & Conditions ("Terms") constitute a legally binding agreement between you ("Player", "User", "you") and sona1 ("sona1", "we", "us", "the Platform") governing your access to and use of the sona1 online casino and sports betting platform, accessible at sona1.bio and any associated mobile or web application (collectively, "the Platform").
By completing the registration process, making a deposit, placing a bet, or otherwise using any feature of the Platform, you unconditionally accept these Terms. If you are accessing the Platform on behalf of another person, you represent and warrant that you have the authority to bind that person to these Terms, and by accepting, you do so on their behalf.
sona1 reserves the right to update, revise, or replace these Terms at any time. Where changes are material, sona1 will provide reasonable notice via email or an on-platform notification. Your continued use of the Platform following the posting of revised Terms constitutes your acceptance of those changes. It is your responsibility to review these Terms periodically.
2. Eligibility Requirements
To register and maintain an active account on sona1, you must satisfy all of the following eligibility criteria at the time of registration and on a continuing basis throughout your use of the Platform:
- You must be at least 21 years of age. sona1 does not permit access to individuals under the age of 21 under any circumstances. This age restriction applies across all regions, including Dhaka, Chittagong, Sylhet, Rajshahi, Khulna, Barisal, Rangpur, and Mymensingh.
- You must be a natural person (not a corporation, partnership, trust, or other legal entity) registering for personal, non-commercial use only.
- You must not be acting as an agent, proxy, or nominee for any other person.
- Online gaming must not be prohibited by the laws of your jurisdiction of residence at the time of registration or play. You are solely responsible for determining the legality of online gaming in your jurisdiction.
- You must not be registered on any self-exclusion database or have previously been excluded from the sona1 platform.
- You must not be an employee, contractor, director, officer, or close family member of sona1 or any of its affiliated software or payment partners.
sona1 reserves the right to request age verification documentation at any time. Failure to provide satisfactory proof of age may result in account suspension and withholding of pending withdrawals pending verification. We take our obligation to prevent underage gambling seriously and apply strict checks accordingly.
3. Account Registration
Each individual may hold only one registered account on sona1. The creation of multiple accounts by a single individual ("multi-accounting") is strictly prohibited and will result in all associated accounts being suspended and any balances being voided without notice.
When registering, you agree to provide accurate, current, and complete information including your full legal name, date of birth, residential address, and valid contact details. You agree to update this information promptly if it changes. sona1 may request supporting documentation to verify the information you provide, including but not limited to:
- A valid national identity card (NID), passport, or other government-issued photo identification.
- Proof of residential address (utility bill, bank statement, or official correspondence dated within the past three months).
- Proof of ownership of the payment method used for deposits (e.g., a screenshot of your bKash or Nagad account showing your registered mobile number).
You are responsible for maintaining the security and confidentiality of your account username and password. You must not share your login credentials with any other person. sona1 will not be held liable for any loss arising from unauthorised access to your account where such access resulted from your failure to maintain credential security.
sona1 reserves the right to refuse any registration application at its sole discretion, without obligation to provide a reason for doing so.
4. Deposits and Withdrawals
All transactions on sona1 are conducted in Bangladeshi Taka (৳). sona1 does not accept transactions in foreign currencies. The following payment methods are currently supported for both deposits and withdrawals:
- Mobile Financial Services: bKash, Nagad, Rocket, Upay
- International Payment Cards: Visa, Mastercard
Deposits are credited to your sona1 wallet upon confirmation from the payment provider. For bKash and Nagad, this typically occurs within seconds. For card-based transactions, processing times may vary. sona1 does not charge fees on deposits; however, your payment provider may apply their own transaction charges.
Withdrawal requests are processed in the order they are received. sona1 aims to process withdrawal requests within one (1) to four (4) business hours for mobile wallet methods and within one (1) to three (3) business days for card-based methods, subject to successful completion of any outstanding identity verification requirements.
The following conditions apply to all withdrawals:
- Withdrawals may only be made to the same payment method and account used to make the most recent deposit. This is a mandatory anti-money laundering (AML) requirement.
- sona1 may require identity verification before processing any withdrawal. Submitting false or fraudulent documents is a criminal offence and will be reported to the relevant authorities.
- A minimum withdrawal amount of ৳500 applies. The maximum single withdrawal amount and daily withdrawal limits are set out in the cashier section of your account.
- Bonus funds that have not satisfied applicable wagering requirements cannot be withdrawn and will be removed from your balance if a withdrawal is requested before wagering is complete.
- sona1 reserves the right to delay or withhold a withdrawal pending investigation if it suspects fraudulent activity, bonus abuse, or a breach of these Terms.
Anti-Money Laundering Notice: sona1 is committed to full compliance with applicable anti-money laundering regulations. We reserve the right to conduct enhanced due diligence on any account and to report suspicious transactions to the relevant financial intelligence authorities where required by law.
5. Bonuses and Promotions
sona1 offers various promotional incentives to registered players including welcome bonuses, deposit match bonuses, free spins, reload bonuses, and seasonal promotions tied to events such as the BPL, IPL, T20 World Cup, Eid, Pohela Boishakh, and other occasions relevant to the Bangladeshi market. All promotions are subject to the following general conditions, in addition to any specific terms communicated at the time of the offer:
- Wagering Requirements: Bonus funds and any winnings derived from bonus funds are subject to wagering requirements before they become eligible for withdrawal. The applicable wagering multiplier will be stated on each promotion page. Unless otherwise specified, the standard wagering requirement is thirty times (30x) the bonus amount.
- Time Limits: All bonuses must be used within the time limit specified in the individual promotion terms. Unused bonus funds will expire and be removed from your account balance at the end of the stated period.
- Game Contributions: Different game types contribute differently toward fulfilling wagering requirements. Slots typically contribute 100%, while table games, live casino titles, and crash games may contribute at a reduced rate or not at all. Specific contribution rates are stated in the promotion terms.
- Maximum Bet Rule: While wagering through a bonus, the maximum permitted bet per spin or round is ৳500 unless a higher limit is explicitly stated. Bets exceeding this limit during active bonus wagering may result in the forfeiture of the bonus and associated winnings.
- One Bonus Per Promotion: Promotions are limited to one per player, per household, per IP address, per device, and per payment account. Attempting to claim the same promotion multiple times constitutes bonus abuse.
- sona1's Right to Amend: sona1 reserves the right to modify, suspend, or withdraw any promotion at any time without prior notice. In cases of suspected abuse, sona1 may void bonus funds and associated winnings and close the relevant account.
6. Game Rules and Conduct
All casino games and sports betting markets available on sona1 are governed by the individual game rules published on the Platform. In the event of any conflict between these Terms and individual game rules, these Terms shall prevail.
All casino game outcomes are determined by certified random number generator (RNG) technology or, in the case of live dealer games, by physical game events conducted in a professionally managed studio environment. sona1 does not manipulate game outcomes in any way and is committed to certified fair play across its entire game library.
In the event of a technical malfunction — including software errors, server failures, telecommunications disruptions, or any interruption to a game session — sona1 reserves the right to void the affected game round and return the wager to the player's account. sona1 will not honour payouts that result from, or are inflated by, a technical error. Players who knowingly exploit a technical malfunction to generate winnings will have those winnings voided and may have their account suspended.
For sports betting, sona1 reserves the right to correct pricing errors, suspend markets, and void bets in circumstances where an event result is uncertain, an event is cancelled or abandoned, or where clear evidence of match manipulation exists. Specific sports betting rules, including settlement procedures for BPL and IPL cricket markets, are published separately within the sportsbook section of the Platform.
7. Prohibited Activities
The following activities are strictly prohibited on the sona1 platform. Engaging in any prohibited activity will result in immediate account suspension, forfeiture of any balance, and may result in legal action:
- Using automated software, scripts, bots, artificial intelligence tools, or any other mechanism to gain an unfair advantage over other players or the Platform.
- Engaging in collusion with other players in any game mode, including coordinated play in live poker, live table games, or tournament formats.
- Exploiting software bugs, pricing errors, or technical malfunctions for financial gain.
- Using the Platform to launder money or to process the proceeds of any illegal activity.
- Providing false information during registration or identity verification, including the use of another person's identity documents.
- Creating or operating multiple accounts, whether in your own name or under aliases.
- Facilitating the use of the Platform by any person who does not meet the eligibility requirements, including persons under the age of 21.
- Engaging in any form of arbitrage or matched betting using sona1 promotions in a manner designed to guarantee profit regardless of outcome.
- Engaging in abusive, threatening, racist, or otherwise inappropriate conduct toward sona1 support staff or other players on the Platform.
- Reproducing, distributing, or commercially exploiting any content, software, or intellectual property belonging to sona1 without express written consent.
8. Account Suspension and Closure
sona1 reserves the right to suspend, restrict, or permanently close any account at its sole discretion, without prior notice, in any of the following circumstances:
- Breach of any provision of these Terms & Conditions.
- Failure to pass identity verification or age verification procedures.
- Reasonable suspicion of fraudulent activity, money laundering, or other criminal conduct.
- Receipt of a chargeback request from the player's payment provider.
- Court order, regulatory directive, or instruction from a competent authority.
- Reasonable belief that the player is exhibiting signs of problem gambling, where account closure is in the player's best interest.
Where an account is closed due to a player breach of these Terms, any remaining balance may be forfeited. Where an account is closed for operational reasons unrelated to player misconduct, any verified balance will be returned to the player's registered payment method within a reasonable time.
Players who wish to close their own account voluntarily may do so by contacting the sona1 support team. Voluntary self-exclusion requests will be processed promptly, and self-excluded players will not be permitted to re-register during the selected exclusion period.

10. Limitation of Liability
To the fullest extent permitted by applicable law, sona1 shall not be liable for any direct, indirect, incidental, consequential, special, or punitive damages arising out of or related to your use of, or inability to use, the Platform, including but not limited to:

Gambling Risk Disclosure: Gambling involves financial risk. The house edge means that, over time, the Platform has a statistical advantage over players. You should only gamble amounts you can afford to lose. Past outcomes do not predict future results. sona1 strongly encourages all players to make use of responsible gaming tools to manage their activity. 21+ only.
11. Privacy and Data
sona1 collects, processes, and stores personal data in accordance with its Privacy Policy, which forms an integral part of these Terms and is available at sona1.bio/privacy-policy. By using the Platform, you consent to the data practices described in the Privacy Policy.
The personal data sona1 collects — including name, date of birth, contact information, payment details, and gaming activity — is used exclusively for the purposes of account management, identity verification, payment processing, regulatory compliance, customer support, and the provision of personalised gaming services. sona1 does not sell personal data to third parties for commercial marketing purposes.
sona1 employs industry-standard 256-bit SSL encryption to protect all personal and financial data in transit. Passwords are stored as secure, salted cryptographic hashes and are never accessible in readable form, even by sona1 staff.

If you do not agree with any amendment to the Terms, you must stop using the Platform and may request account closure. Your continued use of the Platform after the effective date of any amendment constitutes your binding acceptance of the revised Terms.
