No Account Login
The 3phase demo does not use a sign-in screen. You do not enter a username or password to start playing. Access is immediate upon loading the page.
Local Wallet 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.
Identity and Verification
No outside operator or account address is verified here. The original demo has no sign-in or document-upload form. That does not establish anonymity or exclude other processing on the site.
Privacy and Storage
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.
Responsible Use
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.
Game Mechanics Overview
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.
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.
