Game Mechanics: Mirror Subsequences
The core game is called Mirror Subsequences. In each round, the system draws two independent uniform two-digit tickets ranging from 00 to 99, retaining leading zeros. These tickets are concatenated in order to form a four-digit string. The score is determined by the length of the longest palindromic subsequence (L), where characters maintain their original position order but can skip intermediate digits. The raw score is calculated as max(0, L−2). This means a raw score of zero is assigned if the longest palindromic subsequence is two characters or fewer. Note that contiguous substring length is not used for scoring.
The game offers three scoring modes, each separately normalized to ensure an expected gross return of 96%. Players can choose to score the raw value, the square of the raw value, or the cube of the raw value. Choosing a higher power does not change which ticket combinations result in a zero score. The expected gross return is a mathematical expectation over all possible outcomes and is not a guarantee of profit in a single session.
Stake, Settlement, and Controls
One whole captured stake covers both tickets for the entire round. The gross return is 0.96 × captured whole stake × raw score raised to the selected power ÷ the corresponding exact mean. The selected power is 1, 2 or 3. The exact means are 0.281 for mode one, 0.301 for mode two, and 0.341 for mode three.
Controls are locked during active play. The stake, mode selection, and refill button remain disabled while a draw is active and throughout any automatic queue. Sound settings remain available during this time. Settlement normally takes 480ms of animation; reduced-motion mode can settle on the first animation callback. The Auto mode queues at most ten draws. The Stop button cancels future draws in the queue but allows the current draw to settle. There is no early settlement or cash-out control during a draw.
Wallet Behavior and Restoration
The demo wallet persists locally, including balances of zero. A fraction of the balance carries over between settlements, refills, and reloads. The initial balance is 1,000 virtual coins. Restoration is a manual process available only when the wallet is idle and the balance falls below 10. Clicking restore sets the balance to exactly 1,000, preserving any fractional carry. Restoration is not automatic and does not add the reset amount on top of existing funds; it replaces the balance.
Reloading the page ends an unfinished draw without refunding the stake or resuming progress. A saved wallet state does not mean that an unfinished round or all progress automatically resumes upon return. The wallet tracks settled balances and fractional carry but does not maintain active game state across page reloads.
Privacy and Data Storage
The demo uses browser localStorage to store the settled balance and fractional carry. This storage method does not establish anonymity, nor does it prove that no other data processing occurs elsewhere. The template declares a Google Fonts stylesheet; actual browser request capture is pending, so we cannot confirm if other third-party requests are present. Clearing cached files is distinct from removing this site's localStorage data. The game interface does not establish server log retention or encryption guarantees. Privacy claims are limited to what is directly observed in the demo interface.
Identity and Payment Context
The 3star demo operates without a demo account flow or demo payment flow. There is no cashier, no KYC requirement, and no payment method integration. Virtual coins used in this demo have no cash value and cannot be redeemed for real currency. The intended audience for this guide is 18+, which is a policy for this demo experience and not necessarily a claim about local legal age gates or implemented verification systems. No verified operator address, license, or company history is provided for this specific demo instance.
Responsible Use and Limits
Users are encouraged to practice responsible use by setting voluntary breaks and monitoring their time and virtual coin limits. The game mechanics, such as caps and resets, do not guarantee safe behavior or prevent loss. There is no enforced timer, self-exclusion, or account blocking implemented in this demo. Suitable local qualified help can be sought independently, but no specific hotline or support channel is provided by this demo guide. Users should treat the virtual coins as a simulation tool rather than a financial instrument.
Frequently asked questions
Does the demo have a cash value or real money payout?
No. The virtual coins used in the 3star demo have no cash value. There is no cashier, no payment flow, and no mechanism to redeem coins for real currency. The expected gross return of 96% follows from the payout rule over all equally likely outcomes, not a promise of real-world profit.
How does the Restore function work?
Restore is a manual action available only when the wallet is idle and the balance is below 10. It sets the balance to exactly 1,000, preserving any fractional carry. It is not automatic, and it does not add 1,000 to the existing balance; it replaces it. Reloading the page ends the current draw without refund.
What happens if I stop the auto mode early?
The Stop button cancels future draws in the queue but allows the current draw to settle. The controls for stake, mode, and refill remain locked until the active draw and any remaining queue finish. There is no early bank option to withdraw funds during an active round.
