3xx Safety Review: Unverified Identity and Evidence Limits

The brand name 3xx and the domain 3xx.info are treated as a query identity that has not been independently verified against a specific legal entity. No official address, operator, affiliation, company history, or government-issued license has been confirmed for this service. While the name might suggest a connection to other gaming services, this guide does not assume any such relationship unless explicitly supported by a reviewed primary-source fact. Consequently, no commercial comparison, safety rating, or verified track record can be definitively attributed to 3xx based solely on the demo interface. The identity of the entity running this demo remains unverified, meaning users should treat it as an independent browser experience rather than a regulated casino operation.

The 3xx demo features an original game called No Three Square. It uses a four-by-four board drawn uniformly from all possible boards that satisfy a specific constraint: no contiguous two-by-two square has exactly three mines. Players select a mine count, and the board is drawn from this exact finite support. Gross returns are calculated as 0.96 times the captured stake times the initial support size divided by the current compatible support size. Reveals that would exceed a 1000-times-stake cap are disabled, and the current quote is automatically banked when no eligible reveals remain. Manual bank becomes available only after at least one safe reveal. A mine returns zero, ending the round.

The demo uses a local wallet with an initial balance of 1000 virtual coins. The balance persists locally, including fractional carry across settlements and reloads. If the balance falls below 10 while idle, a manual refill sets the integer wallet to 1000. There is no auto queue, and no refill occurs during an active round. Unfinished rounds do not resume upon reload; they end without refund. The captured stake and mine count are locked throughout the round. Settlements are local, with no cash value or cashier associated with the virtual coins.

The source confirms local wallet storage; that observation does not describe every aspect of data processing. The source uses browser localStorage for the settled demo balance and fractional carry. This does not establish anonymity, nor does it exclude other processing by the site. The template declares a Google Fonts stylesheet, but actual browser request capture is pending, so we cannot confirm if other requests or processing are absent. Clearing cached files is distinct from removing this site's localStorage. There is no verified evidence of server logging, encryption guarantees, or data sale beyond what is explicitly declared.

The 18+ audience policy is a guide recommendation and not a verified legal age gate. Responsible use involves practical voluntary breaks and self-monitored limits on time and virtual coins. There is no enforced timer, self-exclusion, or account blocking. Game caps and resets are mechanics, not guarantees of safe behavior. Users are encouraged to monitor their own usage, as the demo does not provide clinical benefits or diagnostic tools. Suitable local qualified help can be sought independently.

• Is 3xx a licensed operator? This guide has not verified a licence or operator identity for the query name 3xx. That is a limit of the evidence, not proof that an outside operator is unlicensed.
• Where is my balance stored? Your balance is stored in your browser's localStorage. It is not synced to a server account.
• Can I win real money? No, the virtual coins have no cash value, and there is no cashier or payment flow.
