The coins have no cash value, deposits, withdrawals or prizes. External licences, apps, accounts and payment services are not established by this guide.
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.
Captured choices and a ten-round queue
Select stake10,20,50 or100 and power1,2 or3 before starting. One stake is deducted once; stake, power and refill lock while one round resolves.
Auto starts at most ten settled rounds and stops earlier if the captured stake cannot be paid. Stop prevents future starts and lets the active round settle. There is no cashout. Sound is optional and reduced motion shortens the animation without changing the word 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 does the board work?
Six independent uniform A/B/C panels define three symbol frequencies. Remove zero frequencies, repeatedly merge the two smallest positive weights and insert their sum back into the ordered queue. Raw reward is the sum of merged weights, the binary Huffman weighted external path length. Only one symbol present means no merge and reward0. The displayed ledger reports all merges automatically; the player does not build a tree interactively.
What are the exact reward means?
All729 words are equally likely. Raw rewards0,6,8,9,10 occur3,186,90,360,90 times. Means of raw, raw² and raw³ are664/81,5624/81 and5416/9. Preselected power1,2 or3 pays0.96×raw^power/E(raw^power). Each mode has96% expected gross return without skill. Gross includes the stake; a positive reward can return less than the stake.
Which examples are possible?
AAAAAA contains only A: no merge, reward0. AAAABB has weights2,4, which merge to6: reward6. AAABBC has weights1,2,3: merge1+2=3, then3+3=6, total9. AABBCC has weights2,2,2: merge2+2=4, then2+4=6, total10. Six panels are sampled from three symbols, not six distinct symbol types.
