The guide focuses on readable rules, collection choices and the local wallet. It does not identify a company, licence holder, official app or payment service behind the search name.
What you can learn here
Use the guide to understand how three numbers are revealed, how the current gross quote is calculated and what happens when you collect. The rules, practical FAQ and browser guide describe the same demo from different angles.
The review page assesses this demo’s behavior and limits. It cannot establish the reputation or commercial terms of an outside business simply because a similar name appears in a search result.
A game built around divisor sums
Divisor Sum Difference reveals twelve fair bits in three four-bit blocks. Each block becomes an integer from 1 to 16. The score compares the divisor sum of the product with the product of the three divisor sums: |σ(abc) − σ(a)σ(b)σ(c)|.
Linear, Square and Cube apply different weights to this score. Each quote is ×0.97 times the mean remaining terminal weight divided by the starting mean. The number on screen is a gross multiplier, which can rise, fall or reach zero.
Collection is part of the round
Choose a stake and optional automatic threshold before starting. Auto ×1.25, ×1.75 and ×2.50 collect at the first qualifying step using the actual quote. Manual collection is available while the round is active.
A zero quote ends the round before collection at that step. If an automatic threshold was crossed earlier, that earlier settlement stands. A surviving positive final-step quote is collected even if no threshold was reached.
Play coins and local persistence
The wallet initially holds 1,000 play coins. These coins cannot be exchanged for money. A round deducts one selected stake; settlement credits the whole part of its gross return plus previous fractional carry and saves the new remainder.
Restore balance is a manual option when idle below 10 coins and sets the balance to 1,000. Balance and carry are stored locally, including a zero balance. An unfinished round does not resume after reload and receives no refund or payout.
Mathematics and observed samples
The payout calculation has an exact unrounded expected gross return of 97% for the tested curves and stopping policies. Whole-coin settlement and saved fractions affect individual credited amounts. An average does not guarantee a session result.
For example, a saved one-million-round Linear simulation with collection at step six measured 96.8965%, while a one-million-round Square simulation left to step twelve measured 96.8531%. These are sample results, rather than alternative payout formulas.
Privacy and audience
The pages load Google Fonts resources and include a Statinside counter with identifier 44. The demo stores its wallet and fractional carry in browser localStorage. The privacy page explains these observations without promising a complete account of third-party handling.
The guide has an 18+ intended audience and does not verify age. It supplies a virtual demo without account registration or payment forms.
Frequently asked questions
Who operates the outside service called Wjcasino?
This guide has not established an outside business identity or licence holder for the search name. It does not invent an operator or affiliation.
Does the demo copy an outside catalogue?
No outside catalogue is established here. The guide describes its own Divisor Sum Difference demo and its displayed rules.
Can I use the guide without registering?
Yes. The demo has no registration or sign-in flow. Its play-coin balance is stored in the browser rather than an account.
