Optional play and personal time limits
Participation is optional and there is no cash prize. You can finish a round and decline another. A personal time limit does not alter the four-draw probabilities. Earlier losses do not improve the next ticket’s chances.
This guide provides no clinical diagnosis, universal legal age or verified outside self-exclusion service. If play disrupts daily life, qualified local support may be appropriate. The demo is not preparation for an identified commercial product.
One captured round without Auto
Choose stake 10,20,50 or100 and one band before starting. The start button captures both and deducts the stake once. Stake, band and refill controls lock while the round is active.
There is no Auto, Stop or cashout. The sound control is optional. Reduced motion shortens the display delay without changing the three samples, scoring or payment.
Free virtual balance and manual restoration
The initial balance is 1,000 free virtual coins, with no monetary value or prizes. Settled balance and fractional payout carry are stored in browser localStorage when available. Whole coins are credited and the remaining fraction is kept for later settlements.
Only while idle and below 10 whole coins can the refill button restore the balance to 1,000. It sets that balance rather than adding 1,000 and preserves fractional carry. Reloading does not automatically refill the wallet.
An unfinished spin is not recovered
The pending four-number result and active round are not saved for resumption. Reloading or leaving during a spin does not recover that round or refund the captured stake. Previously saved balance and fractional carry can remain.
Clearing site storage can remove the local wallet. Clearing cached files alone is a different action. This local demo wallet is not a customer account synchronized across devices.

Frequently asked questions
How is the score computed?
Three independent uniform draws0–12 become periods1–13 by adding one. Raw score is the least common multiple of all three periods: the first positive integer divisible by each period. The displayed panels show periods1–13. Choose band1–30,31–150 or151–1716 before starting. One stake covers the complete three-draw round. There is no Auto, cashout or interactive clock adjustment.
What are the exact returns?
All2197 ordered triples are equally likely. Bands1–30,31–150 and151–1716 contain685,930 and582 triples. Their exact winning gross multipliers are0.96×2197/685,0.96×2197/930 and0.96×2197/582. A matching ticket returns the full gross multiplier times the captured stake; a different band returns zero. Each preselected ticket has96% expected gross return, not96% chance to win. No skill or stopping policy increases it.
Which controls lock?
Choose stake 10,20,50 or100 and one band before starting. The start button captures both and deducts the stake once. Stake, band and refill controls lock while the round is active.

When can I restore balance?
The initial balance is 1,000 free virtual coins, with no monetary value or prizes. Settled balance and fractional payout carry are stored in browser localStorage when available. Whole coins are credited and the remaining fraction is kept for later settlements. Only while idle and below 10 whole coins can the refill button restore the balance to 1,000. It sets that balance rather than adding 1,000 and preserves fractional carry. Reloading does not automatically refill the wallet.
