Purpose and identity
The name 39D identifies a query. Its business identity remains unverified. A similar domain or search position does not establish a company, licence or official address.
Original demo
Twelve independent fair binary steps reveal three four-bit blocks. Add one to each decoded block to obtain a, b and c from 1 to 16. The score is the product of the remainders of a divided by b, b divided by c and c divided by a, minus the minimum zero. Choose linear, squared or cubed weight before starting.
Quote and collection
The quote is 0.97 times the conditional mean of terminal weight divided by its initial mean. It can rise, fall or reach zero. Manual collection settles the current quote; auto off or 1.25, 1.75 and 2.50 are available. An earlier crossing settles before a later zero; zero wins at the same step. Step 12 collects a surviving quote. A crossing pays the full quote, including overshoot.
Wallet and settlement
One stake of 10, 20, 50 or 100 is captured per round. Settlement adds the whole part of unrounded gross return plus previous carry to the wallet and saves the remainder. Idle restoration below 10 sets the wallet to 1000 and preserves carry. Reload retains an interrupted debit without refund, payout or resume; stake 20, Linear and auto off reset.
Audience and evidence
The intended audience is 18+, without an implemented age gate. Coins have no cash value. Expected gross return is 97% for the finite collection policies, not a session guarantee or a promise after abandonment. Fifteen preserved million-round samples support, but do not define, this expectation.
Storage and resources
The whole-coin wallet balance, including zero, and separate fractional carry persist in browser localStorage. Clearing cached files alone need not remove that storage. Reload restores stake 20, Linear and auto off; an interrupted captured stake is not refunded, paid or resumed.

Frequently asked questions
Is 39D an official operator?
Its identity remains unverified. This guide does not establish an official operator, licence or app.
How is balance restored?
While idle and below 10, manual restoration sets the wallet to 1000 and keeps separate fractional carry.
Does reload refund an unfinished stake?
No. The captured stake remains deducted without payout or resume. Controls reset to stake 20, Linear and auto off.
