Identity and Evidence Limits

A name, search snippet or similarly named domain does not identify an official company or app. No outside operator, licence, payment service, customer-support channel or commercial safety verdict is established by this guide.

Wallet and Persistence

A fresh wallet starts at 1000 virtual coins. While idle below 10, manual refill sets the integer balance to exactly 1000 and preserves fractional carry. Settled balance, including zero, and fractional carry persist in this browser when its site storage remains available. Reloading an unfinished round loses that round without refund or resume: its stake has already been debited. The demo has no account, deposits or withdrawals; its coins have no cash value.

Storage and Third Parties

The game saves demo balance and fractional carry in browser localStorage. Clearing cached files alone may leave this site storage intact; removing site storage can reset these local values. This guide declares Google Fonts and uses a Statinside counter in the page build. These observations are not a complete inventory of network requests or data processing, and do not establish anonymity, a retention period or absence of other processing.

Game Mechanics: Spiral No Neighbours

Spiral No Neighbours uses a four-by-four board. Choose 3, 4 or 5 mines; the initial legal-board counts are 364, 715 and 792 respectively. Each legal board is equally likely. Read cells in zero-based order 0,1,2,3,7,11,15,14,13,12,8,4,5,6,10,9: two consecutive entries cannot both contain mines. This reading-order rule does not forbid every geometrically adjacent pair.

Stake choices are 10,20,50,100,200 virtual coins. Stake, mine count and refill are locked during a round; sound remains available. Manual bank is available after at least one safe reveal. Certain mines and safe transitions above 1000 times stake are disabled. All safe cells revealed or no eligible reveal remaining automatically banks the current quote. There is no automatic round queue.

Mathematical Evidence

For a stated safe path followed by banking, its survival probability is remaining boards ÷ initial boards. Multiplying this by its gross quote gives an expected gross return of 0.96 times stake. This expectation concerns legal-board sampling and eligible strategies, not a promised session return. Integer wallet credits round down gross return plus saved fractional carry, retaining the remainder for later settlements.

Responsible Use and Audience

This guide is intended for adults aged 18 and over; that audience policy does not establish local law or implement an age check. Choose a personal time or virtual-coin limit and take breaks. The interface has no account-level blocking or self-exclusion tool. If play interferes with daily life, consider appropriate qualified help in your area.

Frequently asked questions

Is 3phase a verified licensed operator?

This guide does not establish an outside operator’s identity or licence. It provides its own original virtual-coin demo.

How is the wallet restored?

A manual idle-only restoration sets the balance to exactly 1000 when below 10. It preserves fractional carry. It does not add 1000 coins to the existing balance, and replenishment is not automatic.

What is the exact RTP?

A legal safe path followed by banking has expected gross return 96% of stake before integer settlement with carried fractions. This is not a promised session result.
