Purpose and identity limits
The search name 9988 does not establish an outside operator, license, corporate registration, official account address, app or payment service. This independent guide describes its own original demo. Its rules do not establish the identity, safety or terms of an outside business.
The domain and a name in a search result are not evidence of an official relationship. This guide supplies no outside account recovery, customer-service channel or game catalogue.
An original two-reel game
Two independent reels each show one hexadecimal symbol: 0 to 9 or A to F. A, B, C, D, E and F have values 10, 11, 12, 13, 14 and 15. Calculate n = 16 times the first reel value + the second reel value + 1. Each integer from 1 to 256 has probability 1 in 256.
Factor n into prime powers. For each prime power p^e, calculate p^(e-1) times (p+1), then multiply those results together. For n = 1, there are no prime factors and the empty product is 1. Subtract 1 from the product to obtain the reward score. Reels 0 and 0 therefore produce n = 1, a statistic of 1 and a score of 0.
Reward curves and sample results
Linear uses the reward score as its weight. Square uses the score squared, and Cube uses the score cubed. For the selected curve, the gross multiplier is 0.96 times the weight divided by its exact average across all 256 outcomes. Multiply the gross multiplier by the stake to obtain the raw gross return.
The exact sums of those weights are 49,692 for Linear, 13,767,778 for Square and 4,569,348,930 for Cube. Divide each sum by 256 to find its exact mean. Every curve has an expected gross return of 96% of the stake across the complete outcome distribution. This is an average, not a probability of winning or a promised session result.
Separate runs of one million simulated rounds per curve measured gross returns of 95.89% for Linear, 95.99% for Square and 95.84% for Cube. These are sample observations; the exact expectation comes from summing all 256 outcomes and is 96% for each curve.
The curves assign different relative rewards to scores. Equal expected return does not make their individual round results identical. A gross return includes any returned part of the stake; it is not additional profit.
A browser wallet with clear limits
A new demo wallet starts with 1,000 play coins. The balance and fractional payout carry are stored in this browser's local storage. A settled balance of zero is saved too. The coins have no cash value and cannot be purchased, withdrawn or exchanged for money.
When no round is active and the balance is below 10, Restore balance sets it to exactly 1,000. At a balance of 10, restoration is unavailable. This manual action replaces the balance rather than adding 1,000 coins, and keeps the fractional carry.
Reloading during a spin ends that unfinished round. The stake already deducted remains deducted, with no refund, payout or resumed round. The saved wallet and carry remain, while the controls return to stake 20 and Linear.
Wait for settlement before reloading if you want the round to complete. Stored wallet values are local browser state, not an online account or a guarantee of recovery after site data are deleted.
Storage and external requests
The demo stores its virtual-coin balance and fractional payout carry in browser local storage. The pages also load Google Fonts stylesheets and font files, and Statinside visitor analytics with counter 44. These third-party requests go beyond local wallet storage.
There is no demo account or payment flow. That does not establish anonymity or the absence of personal-data processing. This guide does not establish what each provider retains, for how long, or for which purposes.
Clearing cached files can leave local storage intact. Use the browser's controls for this site's stored data if you intend to remove the saved wallet and carry. Removing those values can discard them; it is not account recovery or an implemented self-exclusion tool.
Another person using the same browser profile can access the wallet shown by the demo. There is no sign-in that separates personal wallets, and this guide does not promise synchronization across devices.
Intended audience and voluntary breaks
This guide and its demo are intended for people aged 18 or older. This is the guide's audience policy, not an enforced age check or a determination of the legal age for an outside activity.
You can choose personal time and play-coin limits and take breaks between rounds. These are voluntary decisions; the interface does not enforce timers, account blocks or self-exclusion. Stop using the demo if it interferes with your plans, and seek appropriate qualified local help if gaming habits cause concern.
