Idempotent Stamp: Practical Questions

The official website of qq7887.

The official website of qq7887. This guide answers practical questions about the Idempotent Stamp demo. The game uses a 3x3 matrix over GF(2). Rewards are calculated using powers 1, 2, or 3, each normalized to a 96% expected gross return. One whole stake is captured per board. There is no Auto, Stop, or cash-out. The demo uses a virtual wallet that can be restored manually under specific conditions.

How Scoring Works

Nine fair bits form a 3 by 3 matrix A. The reward is one when A squared equals A over GF(2), otherwise zero; the zero matrix is included. The raw reward raised to power 1, 2 or 3 is separately normalized by its exact mean over all equally likely complete draws, giving 96% expected gross return in each mode.

Controls and Modes

Stake buttons are 10, 20, 50 and 100. One whole stake is captured per board; there is no Auto, Stop or cash-out. The controls and modes are fixed as described in the source-bound rules.

Settlement and Payouts

Actual payout math and every mode are recorded in the source-bound mathematical evidence; displayed multipliers are gross coin returns, not profit. Fractional payout change persists through settlement.

Wallet and Restoration

An idle balance below 10 can be restored manually to 1,000; fractional payout change persists, and an unfinished draw is not refunded on reload. The restoration is a manual set, eligible while idle when the balance is below 10.

Unfinished Reloads

An unfinished round ends without refund or resume. If you reload the page during a draw, the state is not preserved for that specific round.

Privacy and Storage

Game source uses localStorage for settled balance and fractional carry; this does not establish anonymity or exclude other processing. The template declares Google Fonts stylesheet; actual full-site network capture remains pending.

Frequently asked questions

What is the exact scoring condition?

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.

How is the expected return calculated?

The raw reward raised to power 1, 2 or 3 is separately normalized by its exact mean over all equally likely complete draws, giving 96% expected gross return in each mode.

What stake options are available?

Is there an Auto or Stop feature?

No. There is no Auto, Stop or cash-out. One captured whole stake per complete draw.

How does the wallet restoration work?

An idle balance below 10 can be restored manually to 1,000. This is a manual set, not an automatic replenishment.

Does fractional carry persist?

Yes, fractional payout change persists through settlement, manual refill and reload.

What happens if I reload during a game?

An unfinished round ends without refund or resume. The balance settles locally, but the specific round is not refunded.

What storage is used?

Game source uses localStorage for settled balance and fractional carry; this does not establish anonymity or exclude other processing.
