Since no official app is confirmed, sideloading may carry risks. Always verify the source before downloading. The browser-based demo remains the safest way to play without dealing with unverified files or account security bypasses.
APK and Installation Facts
No official APK package has been reviewed or linked from this guide. The absence of an installation file in this demo does not prove that no external package exists, nor does it certify the security or origin of any third-party APK.
Users seeking to install an APK should verify the source independently. This demo operates entirely within the browser environment and does not require sideloading or specific operating system permissions to run.
What Philippines Players Should Check
Before engaging with qq7887, readers in the Philippines should verify key details directly with the operator. First, confirm if the brand officially supports GCash or Maya for transactions, as these are the most common digital wallets here. You can check this by looking for the payment section on their site or contacting their support team.
Next, check if qq7887 holds a license from PAGCOR, the national regulator. Many online gaming brands operate without local licensure, so verify their regulatory status to ensure fair play. Always use the browser demo for safety, as the APK is unverified. Check for clear terms on virtual coin usage and data privacy. Finally, ensure your device allows sideloading only if you trust the APK source, and keep your PHP account details secure when playing.
- Verify GCash/Maya support with the operator
- Check PAGCOR licensing status

Browser Demo Mechanics
The game Idempotent Stamp runs as a browser simulation. The mathematical rules are fixed and do not depend on a server-side app state.
- Core Rule: Nine fair bits form a 3 by 3 matrix A. Reward is one when A squared equals A over GF(2), otherwise zero; the zero matrix is included.
- Modes: The raw reward is raised to power 1, 2, or 3. Each mode is separately normalized by its exact mean over all equally likely complete draws.
- Return: This normalization gives a 96% expected gross return in each mode.
- Controls: Stake buttons are 10, 20, 50 and 100. One whole stake is captured per board. There is no Auto, Stop or cash-out.
Wallet and Persistence
The demo wallet is local to this browser session.
- Initial Balance: 1000 virtual coins.
- Restoration: An idle balance below 10 can be restored manually to 1,000. This is a manual set, not an automatic replenishment.
- Fractional Carry: Fractional payout change persists through settlement, manual refill and reload.
- Unfinished Rounds: An unfinished draw is not refunded on reload. The round ends without resume capability.
Mathematical Evidence
Simulation measurements are supporting sample observations, not the mathematical payout law. The exact expected value is distinct from measured estimates.
| Mode (Power) | Expected RTP | Measured RTP | Final Carry |
|---|---|---|---|
| 1 | 96.00000000000006% | 96.0345335174488% | 0.7034482755955196 |
| 2 | 96.00000000000006% | 95.9862289657244% | 0.7931034480094468 |

Privacy and Storage
This demo uses localStorage for settled balance and fractional carry. This does not establish anonymity or exclude other processing by the browser or network.
The template declares a Google Fonts stylesheet; actual full-site network capture remains pending. The absence of account or payment controls in the demo does not prove that no personal data are processed.
Responsible Use
18+ is this guide's own intended audience; it is not a universal legal age, an implemented age gate, or a statement of local legality.
You can take breaks between draws, follow voluntary time or coin limits, and seek qualified local help. The demo does not make losses safe or provide clinical training.
