How Inverse Hamming Scoring Works
Nine fair bits are arranged into a 3 by 3 matrix A. If the matrix is singular, the reward is zero. If it is non-singular, the reward counts the nonzero entries in the unique inverse over GF(2). This reward is then raised to a power of 1, 2, or 3. The result is normalized by its exact mean over all equally likely complete draws. This gives a 96% expected gross return in each mode.
Game Modes and Controls
There are three modes based on the power applied to the raw reward. Each mode is normalized to a 96% expected gross return. There is no Auto, Stop, or cash-out. One whole stake is captured per board. Stake buttons are 10, 20, 50, and 100. Stake, mode, and refill are locked during active play. Sound remains available. Cricket shot choice remains available between deliveries. Mines eligible picks and collect remain available.
Wallet, Restoration, and Reloads
The initial balance is 1,000. An idle balance below 10 can be restored manually to 1,000. Fractional payout change persists through settlement, manual refill, and reload. The local settled balance including zero persists. An unfinished round ends without refund or resume. Restoration does not add the reset amount and is not automatic. A saved wallet does not mean a round or all progress resumes.
Settlement and Rounding
Actual payout math and every mode are recorded in the source-bound mathematical evidence. Displayed multipliers are gross coin returns, not profit. Rounding is handled sensibly for long floating-point computational artifacts. The final carry values are recorded for each mode. Fractional payout change persists.
Mathematical Evidence and RTP
Expected RTP is a mathematical expectation, not a win probability. Measured simulation percentages are sample observations. For power 1, the expected RTP is 96%, with a measured RTP of 96.21851% over 1,000,000 rounds. For power 2, the expected RTP is 96%, with a measured RTP of 95.82647% over 1,000,000 rounds. For power 3, the expected RTP is 96%, with a measured RTP of 96.24641% over 1,000,000 rounds. Sample size is 1,000,000 rounds for each mode.
Site Facts and Identity
The intended audience is 18+, which is a guide audience policy, not a universal legal age or implemented age gate. The game source uses localStorage for settled balance and fractional carry. This does not establish anonymity or exclude other processing. The template declares a Google Fonts stylesheet. Actual full-site network capture remains pending. There is no demo account flow and no demo payment flow. Virtual coins have no cash value.
Frequently asked questions
What is Inverse Hamming?
Inverse Hamming is a browser demo where nine fair bits form a 3 by 3 matrix A. Singular matrices reward zero. Non-singular matrices reward based on nonzero entries in the unique inverse over GF(2). Rewards are raised to powers 1, 2, or 3 and normalized by their exact mean. Each mode has a 96% expected gross return. One whole stake is captured per board. There is no Auto, Stop, or cash-out. Stake buttons are 10, 20, 50, and 100. An idle balance below 10 can be restored manually to 1,000. Fractional payout change persists. An unfinished draw is not refunded on reload.
How is the reward calculated?
The reward counts the nonzero entries in the unique inverse over GF(2) for a non-singular matrix. This raw reward is raised to a power of 1, 2, or 3. It is then normalized by its exact mean over all equally likely complete draws. This normalization results in a 96% expected gross return for each mode.
What are the stake buttons?
The stake buttons are 10, 20, 50, and 100. One whole stake is captured per board. There is no Auto, Stop, or cash-out. Stake, mode, and refill are locked during active play.
Can I cash out early?
No. There is no Auto, Stop, or cash-out. One whole stake is captured per board. The game runs to completion for each draw.
What is the expected RTP?
The expected RTP is 96% for all three modes. This is a mathematical expectation, not a win probability. Measured simulation percentages are sample observations. For power 1, the measured RTP is 96.21851% over 1,000,000 rounds. For power 2, it is 95.82647%. For power 3, it is 96.24641%.
How does the wallet work?
The initial balance is 1,000. An idle balance below 10 can be restored manually to 1,000. Fractional payout change persists through settlement, manual refill, and reload. The local settled balance including zero persists. An unfinished round ends without refund or resume.
What happens if I reload the page?
An unfinished draw is not refunded on reload. An unfinished round ends without refund or resume. A saved wallet does not mean a round or all progress resumes. Restoration does not add the reset amount and is not automatic.
Can I restore my balance manually?
Yes, if your idle balance is below 10, you can restore it manually to 1,000. This is eligible while idle. Fractional payout change persists.
Are the virtual coins worth real money?
No. Virtual coins have no cash value. There is no cashier and no payment flow. The demo does not have an account flow.
Is my data private?
The game source uses localStorage for settled balance and fractional carry. This does not establish anonymity or exclude other processing. The template declares a Google Fonts stylesheet. Actual full-site network capture remains pending.
What is the audience policy?
The intended audience is 18+. This is a guide audience policy, not a universal legal age or implemented age gate.
What are the controls during play?
Stake, mode, and refill are locked during active play. Sound remains available. Cricket shot choice remains available between deliveries. Mines eligible picks and collect remain available.
