Game Mechanics and Optimization
The Seventeen Coin Repair is an independent roulette-family optimization demonstration, distinct from a standard European roulette paytable. The core objective is to form the minimum number of coins totaling exactly 17.
- The system automatically finds the fewest coins whose values sum to exactly 17. Unlimited coins are available in denomination 1 and in each of the four denominations (wheel reading + 1). Repeated values do not create additional denomination types. Each wheel independently draws a uniform value from 0 to 7. The player does not choose the solution. One whole virtual stake of 10, 20, 50 or 100 is captured per round.
- Inputs: Four independently uniform custom wheel readings (0–7) supply the labelled inputs.
- Optimization: The optimum calculation is performed automatically; the player does not manually choose an optimization solution.
- Reward Powers: Modes 1, 2, and 3 each utilize their own exact 4096-draw mean, providing a 96% expected gross return.
Wallet, Refills, and Persistence
The demo wallet operates on local state without an external account login flow.
- Initial Balance: 1000 virtual coins.
- Manual Restoration: When the balance drops below 10 while idle, the user may manually restore the balance to exactly 1000. This action sets the balance; it does not add coins to a previous sum.
- Fractional Carry: Fractional changes persist through settlement, manual refill, and reload.
- Reload Behavior: An unfinished round ends without refund or resume upon reload. The stake is deducted and saved at round start. Reload keeps that deduction, discards the unfinished result and does not resume the round. Previously saved fractional carry remains.
Stakes, Controls, and Stopping
Controls are locked during active play, while sound remains available.
- Stakes: One whole stake per draw, chosen from 10, 20, 50, or 100.
- Auto/Stop: There is no automatic queue or early cash-out option. Each draw captures one whole stake.
- Refill Lock: The refill button is locked while play is active.
Payouts and Mathematical Evidence
Displayed multipliers represent gross coin returns, not net profit. The actual payout math is recorded in the source-bound mathematical evidence.
| Mode | Expected RTP | Measured % (1M rounds) |
|---|---|---|
| 1 | 96% | 96.00838499999999% |
| 2 | 96% | 95.931015% |
| 3 | 96% | 95.924645% |
Simulation measurements are supporting sample observations and do not constitute the mathematical payout law or a promised return.
Privacy and Data Storage
Privacy claims are limited to what is explicitly observable in the source code.
- Storage: The game source uses localStorage for settled balance and fractional carry. This does not establish anonymity or exclude other processing.
- Third Parties: The template declares a Google Fonts stylesheet; actual full-site network capture remains pending.
- Data Processing: The absence of account controls does not prove that no personal data are processed.
Audience and Responsible Use
18+ Audience: This 18+ designation is this guide’s own intended audience policy, not a universal legal age or an implemented age gate.
Responsible use involves optional pauses and monitoring your personal time and virtual-coin limits. The demo does not clinically train behavior or make losses safe. It does not promise account-level blocking, timers, or self-exclusion tools.
Frequently asked questions
Do the virtual coins have cash value?
No. The virtual coins in this demo are for demonstration purposes only and hold no real-world cash value. There is no payment or account service associated with them.
How does the balance restoration work?
When the balance is idle and below 10, you can manually restore it to exactly 1000. This sets the balance; it does not add to any remaining fractional carry from previous rounds.
What happens if I reload the page mid-game?
An unfinished round ends without refund or resume. The stake is deducted and saved at round start. Reload keeps that deduction, discards the unfinished result and does not resume the round. Previously saved fractional carry remains.
