The game involves forming a 3x3 matrix from nine fair bits and checking if it is idempotent. There is no account login, payment processing, or external cashier in this demo. The 18+ label indicates this guide's intended audience policy, not a universal legal age or implemented age gate.
Game Mechanics and Rules
The core mechanic of Idempotent Stamp relies on linear algebra over the finite field GF(2). Nine fair bits are used to form a 3x3 matrix A. A draw is considered a reward (value of one) when the matrix squared equals the matrix over GF(2); otherwise, the reward is zero. The zero matrix is included in the possible outcomes.
There are three distinct modes, defined by raising the raw reward to a power of 1, 2, or 3. Each mode is separately normalized by its exact mean over all equally likely complete draws. This normalization results in an expected gross return of 96% in each mode. The gross payout includes the stake, meaning the displayed multipliers represent total coin returns, not just profit.
Control inputs are limited to stake selection and manual intervention. Stake buttons allow bets of 10, 20, 50, or 100 virtual coins. One whole stake is captured per board. There is no Auto-play, no Stop button, and no cash-out feature during a draw. The game does not support early cashout or an automatic queue.
What Philippine Players Should Check
For players in the Philippines, it is important to verify how qq7887 handles local preferences. While this demo uses virtual coins, you should check if the operator accepts PHP (Philippine peso) for real-money play. Common local payment methods like GCash and Maya are widely used, but you must confirm their availability directly with the operator, as they may not be listed here.
Regulatory status is another key factor. PAGCOR is the national regulator, but you need to check if qq7887 holds a valid license or operates under specific Philippine regulations. To ensure safety, verify the operator's contact details and terms of service on their official site. Always practice responsible play, as gambling legality depends on local law and applies to adults only.
- Check if GCash and Maya are supported for deposits.
- Verify PAGCOR licensing status directly with the operator.
- Confirm that the currency used is PHP.
Mathematical Evidence and Payouts
The mathematical payout law is distinct from simulation measurements. The following table displays the exact expected values and supporting sample observations from the source-bound evidence.
| Mode (Power) | Expected Gross RTP | Measured RTP (Sample) |
|---|---|---|
| 1 | 96.00000000000006% | 96.0345335174488% |
| 2 | 96.00000000000006% | 95.9862289657244% |
| 3 | 96.00000000000006% | 95.64470731055003% |
The expected RTP is exactly 96% for all modes. Measured RTP values are supporting sample observations and do not constitute the mathematical payout law or a promised return. Fractional carry persists through settlement, manual refill, and reload.
Wallet and Balance Mechanics
The demo uses a local virtual wallet. The initial balance is 1000 virtual coins. If the idle balance falls below 10, it can be manually restored to exactly 1000. This restoration sets the balance; it is not an addition of coins or an automatic replenishment.
Fractional payout changes persist even after a manual refill. The settled balance, including zero, persists locally. However, if an unfinished round ends due to a page reload, it is not refunded, nor does it resume. Stake, mode, and refill controls are locked during active play, while sound remains available.
Privacy and Storage
Based on observed source code, the game uses localStorage for settled balance and fractional carry. This does not establish anonymity or exclude other processing. The absence of account or payment controls in the demo does not prove that no personal data are processed.
The template declares a Google Fonts stylesheet, but actual full-site network capture remains pending. Clearing cached files may leave local storage intact. No third-party data processing is explicitly confirmed by the demo alone.
Identity and Verification Status
The queried brand is qq7887. This guide does not establish an official company, account address, app, or service. A search snippet, similarly named domain, or search position is not evidence of an official operator.
Identity is unknown except for individually reviewed primary-source facts. There is no verified app, licence, bonus, payment method, KYC process, support channel, or financial service established by this query. This demo does not certify or reproduce any outside product.
Responsible Use and Audience
The 18+ label indicates this guide's intended audience policy, not a universal legal age, an implemented age gate, or a statement of local legality. You can take breaks between draws and follow a personal time or virtual-coin limit manually. You may seek appropriate local qualified help.
The demo does not clinically train behaviour or make losses safe. It does not promise account-level blocking, a timer, or self-exclusion tools that the interface does not have. Virtual coins have no cash value.
Frequently asked questions
How is the reward calculated in Idempotent Stamp?
Nine fair bits form a 3x3 matrix A. The reward is one when A squared equals A over GF(2), otherwise zero. The zero matrix is included. The raw reward is raised to power 1, 2, or 3 and normalized by its exact mean, giving a 96% expected gross return in each mode.
Can I restore my balance if it runs out?
Yes. An idle balance below 10 can be restored manually to exactly 1,000. Fractional payout changes persist through this refill and reload.
Is this a real money casino?
No. This is an independent demo with virtual coins that have no cash value. There is no account login, payment processing, or external cashier. The queried brand qq7887 is unverified outside of reviewed primary sources.
Is qq7887 licensed in the Philippines?
This independent guide does not confirm licensing. You must check with the operator or visit the PAGCOR website to verify if qq7887 holds a valid Philippine license.
Can I use GCash or Maya on qq7887?
Payment methods vary. This demo uses virtual coins. You should check the operator's cashier or contact support to confirm if GCash and Maya are accepted for real-money transactions.
