For readers in the Philippines, it is important to understand that this is a free demo. You should verify local regulations and payment methods directly with the operator before playing with real money.
Board Support and Drawing Logic
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.
What Philippine Players Should Check
When playing 3phase in the Philippines, always verify the currency settings. Most local players prefer using Philippine pesos (PHP) for clarity, but you must check if the operator supports this. It is also wise to confirm if local digital wallets like GCash and Maya are accepted for deposits, as these are common payment methods in the country. You can find this information in the payment section of the operator’s site.
Regulatory safety is key. Ensure the operator is licensed by PAGCOR, the national regulator, if you are playing locally. Always check the terms and conditions to confirm the brand’s legal status. Use these practical safety steps: read the rules, check the currency, and verify the regulator.
- Check if GCash or Maya is supported.
- Verify PAGCOR licensing status.
- Confirm PHP currency support.
Payout Formula and Gross Quote
After a safe reveal, gross quote = 0.96 × captured stake × initial legal-board count ÷ remaining compatible-board count. The stake is debited at the start; gross return includes the returned stake, so net round change is gross return minus captured stake. A mine returns zero. With 3 mines, safely revealing cell 0 leaves 286 of 364 boards and gives 1.221818… times stake; safely revealing cells 0,1,2 leaves 165 and gives 2.117818… times stake. Cell indices here start at zero; button labels start at one.
Controls, Modes and Stopping Rules
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 and RTP
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.
Wallet, Persistence and Refill
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.
Privacy and Storage Observations
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.
Frequently asked questions
How is the board drawn in Spiral No Neighbours?
The board is drawn uniformly from all legal boards where the 16-bit word (read clockwise outer spiral then inner cells) has no two consecutive mines. This creates a specific support constraint that limits the possible board configurations.
What happens when no eligible reveals remain?
The current quote is automatically banked after all safe cells are revealed or when no eligible covered cell remains. Cells with zero safe probability or a safe quote above1000 times stake are disabled.
Does the demo use real money or accounts?
No. This is a virtual-coin demo with no account login flow or payment processing. The wallet balance persists locally in your browser's storage. Coins have no cash value.
Is 3phase legal in the Philippines?
Legality depends on local law. Check if the operator holds a valid license from PAGCOR. Always confirm the brand’s status with the official operator site.
Can I use GCash or Maya for 3phase?
You should check the payment methods section on the operator’s site. GCash and Maya are common in the Philippines, but support varies by operator.
