Mirror Subsequences: Rules and Expected Return

The official website of 3star.

The official website of 3star. Mirror Subsequences is an original browser-based demo game that uses two independent two-digit tickets to calculate scores based on palindromic subsequences. This guide explains the exact mechanics, controls, and mathematical expectations of this demo, distinguishing them from commercial 2D lottery games.

For readers in Malaysia, it is important to note that this is a free demo using virtual coins. It does not involve real cash gambling under Malaysian law, but you should verify if the operator offers cash games elsewhere.

Game Mechanics and Scoring

The game begins by drawing two independent uniform two-digit tickets ranging from 00 to 99, retaining leading zeros. These two tickets are concatenated in order to form a four-digit sequence. The core scoring function identifies the longest palindromic subsequence within this sequence, preserving the original position order while allowing for character deletions. Note that contiguous substring length is not used for scoring.

The raw score is calculated as the maximum of zero and the length of this longest palindromic subsequence minus two. For example, if the four digits are 0, 0, 0, 0, the longest palindromic subsequence is length four, resulting in a raw score of two. If the digits are 0, 1, 2, 3, the longest palindromic subsequence is length one, resulting in a raw score of zero.

One whole captured stake covers both tickets simultaneously. The player then chooses one of three score modes: score, score squared, or score cubed. Each mode is separately normalized over all 10,000 equally likely ordered ticket pairs to achieve a 96% expected gross return. The powers one, two, and three do not alter which raw scores are zero; they only scale the payout for non-zero scores.

What Malaysian Players Should Check

Before engaging with 3star, Malaysian users must verify several key operational details. First, confirm the currency used for any potential real-money games; it is typically MYR (Malaysian ringgit), but this is not guaranteed for the demo version. Second, check which local payment methods are supported for deposits if you decide to play for real money elsewhere. Common options in Malaysia include Touch 'n Go eWallet and DuitNow, but you must confirm their availability directly with the operator.

Additionally, gambling is tightly restricted by national law in Malaysia. While 3star.cc offers a free demo, ensure you are of legal age and understand that the operator may not be licensed by Malaysian authorities. Always check the 'Terms and Conditions' or 'About Us' section on their site to verify their licensing jurisdiction and dispute resolution process. Practicing responsible play is essential, as demo wins do not guarantee real-money returns.

  • Verify if the operator holds a valid licence from a recognized jurisdiction.
  • Confirm support for Touch 'n Go eWallet or DuitNow for future deposits.
  • Check that the site uses SSL encryption for data security.

Payout Formula and Settlement

The gross return for a round is calculated using the formula: Gross = 0.96 × captured whole stake × raw^(selected mode + 1) / mean[selected mode]. The exact mean values for the three modes are 0.281 for linear, 0.301 for squared, and 0.341 for cubed.

Settlement occurs after a 480ms capture period. During this time, and throughout any active auto-queue, the stake, mode selection, and refill controls are locked, though sound remains available. The expected gross return is 96%, which is a mathematical expectation over many rounds and not a guarantee of net profit in a single session. Saved sample data from one million rounds per mode is consistent with this separate mathematical calculation, with observed returns ranging between 95.97% and 96.35% depending on the mode.

Controls and Auto Modes

The interface offers several control modes to manage gameplay flow. Auto10 queues at most ten captured draws in advance. If a player presses Stop, it cancels future draws in the queue while allowing the current draw to settle. There is no early settlement control during a draw.

Settings, refill, and restoration controls are locked until settlement is complete and the queue finishes. This ensures that the mathematical state of the round is finalized before further actions can be taken. Sound controls remain available during active settlement and queueing to provide audio feedback without affecting the game logic.

Wallet Behavior and Restoration

The demo uses a local virtual wallet with an initial balance of 1,000. Fractional carry persists across settlement, refill, and reload, meaning small decimal differences in balance are preserved rather than rounded to zero. The settled balance persists locally, including when it reaches zero.

Players can manually restore their balance when idle and the balance falls below 10. This action sets the balance to 1,000 and preserves any existing fractional carry. It is not automatic and does not add the reset amount to the current balance; it replaces it. Reloading the page or browser ends an unfinished draw without refund or resume of progress. A saved wallet does not mean a round or all progress resumes upon reload.

Mathematical Evidence and Expectations

The game's mathematics are based on 10,000 equally likely ordered ticket pairs. The expected gross return is exactly 96% for all three modes. This is a long-term mathematical expectation, not a win probability or a target to recover over one session.

Simulation evidence from one million rounds per mode shows measured returns close to the expected value. For power one, the measured RTP was approximately 95.98%. For power two, it was approximately 96.36%. For power three, it was approximately 96.13%. These sample observations support the separate mathematical calculation and illustrate that measured results vary. The demo credits whole coins at settlement and carries the fractional remainder forward.

Identity and Privacy Context

This demo is an independent virtual-coin browser application. It does not identify an outside gaming operator. The brand 3star and website 3star.cc are unverified in this context, meaning no official address, license, or corporate history is confirmed by this guide. The demo has no account flow, no cashier, and no cash value for virtual coins.

Privacy is managed via browser localStorage, which stores the settled demo balance and fractional carry. This does not establish anonymity or exclude other processing. The template declares a Google Fonts stylesheet, but actual browser request capture is pending. Clearing cached files is distinct from removing this site's localStorage. The intended audience policy is 18+, but this is a guide policy, not an implemented age gate.

Frequently asked questions

How is the raw score calculated?

The raw score is the length of the longest palindromic subsequence in the concatenated four-digit ticket pair, minus two. If the result is negative, it is treated as zero. For example, tickets 00 and 00 create the sequence 0000, with a longest palindromic subsequence of length 4, resulting in a raw score of 2.

What happens if I stop the auto-draws early?

Pressing Stop cancels future draws in the queue while the current draw continues to settle. There is no early settlement control during a draw. Controls remain locked until the current draw settles and the queue finishes.

Is the 96% return guaranteed?

No, 96% is the expected gross return over a large number of rounds. It is a mathematical expectation, not a guarantee of net profit in a single session. Short-term results may vary, as shown by simulation data ranging from 95.97% to 96.35%.

Is 3star licensed in Malaysia?

The demo site does not state it is licensed by Malaysian authorities. You must check the operator's official terms to see if they hold a licence from jurisdictions like Malta or the UK, which may not cover Malaysian players directly.

Can I win real money here?

No, this is a free demo using virtual coins. To win real money, you would need to play a cash game on the operator's main platform, if available. Check if they accept MYR and support Touch 'n Go or DuitNow for deposits.
