Readers in Canada should note that this demo uses virtual currency, not real Canadian dollars (CAD). Any connection to real-money play or specific payment methods like Interac e-Transfer depends entirely on the operator's current offerings, which you must verify directly with them.
How the reward score is formed
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.
What Canadian Players Should Verify
Before engaging with the brand 9988 beyond this demo, Canadian residents must confirm several key details. First, verify the currency used for real-money play. While this demo is free, real accounts may use CAD or other currencies. Check the operator's payment page for current listings.
Second, confirm accepted payment methods. Interac e-Transfer is widely used in Canada, but 9988 may not support it. Look for a "Payments" or "Banking" section on the operator's site to see if Interac is listed. If not, check for other common Canadian options.
Third, understand the regulatory landscape. Canada's gambling regulation is provincial. Ontario has its own licensed market, while other provinces have different rules. Ensure 9988 is licensed in your specific province. You can check this by looking for a license number in the website footer and verifying it on the provincial regulator's website, such as the Alcohol and Gaming Commission of Ontario (AGCO). Finally, practice responsible play. Set limits and ensure you are of legal age in your province.
- Check the operator's "Payments" page for Interac e-Transfer support.
- Verify the license number in the footer matches your provincial regulator (e.g., AGCO in Ontario).
- Confirm the legal age for gambling in your specific province.
What the reward curves change
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.
Controls before and during a spin
Select a stake of 10, 20, 50 or 100 play coins and a Linear, Square or Cube reward curve before pressing Spin both reels. The default stake is 20 and the default curve is Linear. Both reels share one stake, deducted once when the round starts.
Stake and curve selection, balance restoration and starting another spin are locked during the round. Sound remains available. Settlement occurs once at the end, with no row bets, bonus or intermediate collection. The chosen stake and curve remain selected after settlement; reloading restores 20 and Linear.
Settlement and manual restoration
At settlement, add the saved fractional carry to the raw gross return. Credit the whole-number part of that total, rounding down, and save the remaining fraction for later rounds. For example, a raw return of 12.4 coins with 0.8 carried forward credits 13 coins and leaves 0.2 as carry.
A zero-return round leaves the saved fraction unchanged. The displayed wallet changes by the single stake deduction and the eventual whole-coin credit, rather than by a separate profit award.
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.
Saved wallet values and reloads
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.
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.
Storage, audience and identity limits
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.
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.
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.
Frequently asked questions
How is the reward score calculated?
Read the reel pair as n = 16 times the first value + the second value + 1. For each prime power p^e in n, multiply p^(e-1) by (p+1), multiply those terms together, then subtract 1. For n = 1 the empty product is 1 and the score is zero.
What happens to fractional returns?
The raw gross return and saved carry are added together. The whole-number part is credited and the remaining fraction is saved. Zero-return rounds and manual restoration keep the carry.
What happens if I reload during a spin?
The deducted stake remains deducted. The unfinished round ends without refund, payout or continuation. Saved wallet values remain; the controls return to stake 20 and Linear.
Is this demo game available to players in Canada?
Yes, this independent demo is accessible from Canada. However, it uses virtual coins, not real CAD. Real-money availability depends on the operator's licensing in your province.
Does 9988 accept Interac e-Transfer for Canadian players?
This guide does not confirm that. You must check the operator's official payment page to see if Interac e-Transfer is currently supported for Canadian accounts.
