An independent guide, not a verified operator
Melolo is the query name used by this independent guide. Square Divisor Sum Mines is this guide’s own original demonstration. A matching name, search result or domain does not establish an outside company, licence, affiliation, official account or app. Those external facts remain unverified here.
The labelled board and restricted layouts
The board has four rows and four columns, labelled 1–16 in row order. Choose 3, 4 or 5 hazards before starting. A complete hazard set is eligible only when the sum of the positive-divisor counts of its labels is a perfect square. For example, label 6 has four positive divisors: 1, 2, 3 and 6. Layouts are sampled uniformly from the eligible sets, not from all ordinary grids.
Exact probabilities change after safe reveals
There are 93 eligible layouts with 3 hazards, 228 with 4 and 650 with 5. Revealing a safe cell removes every layout in which that cell was hazardous. The next safe probability is the number of remaining layouts where a cell is safe divided by the total remaining layouts. The displayed percentage is rounded to one decimal place; pricing uses the exact fraction. Printed labels define the restriction, rather than independent equal cell risks.
Exact rules and measured samples
The probability-based pricing rule and the finite set of eligible layouts define the mathematics. Tests of completed stopping policies have a 97% expected raw gross return; simulations are sample measurements around that benchmark. This is not a guaranteed session return, and abandoning an unfinished round follows the zero-refund reload rule. Rounded cell percentages must not replace the exact fraction in pricing.
Local storage and third-party requests
The browser stores virtual balance and fractional carry locally. Clearing cached files may leave localStorage; clearing this site’s stored data is a separate browser action. Pages load Google Fonts and the Statinside visitor counter. No login or payment form is implemented, but that does not prove the absence of personal-data processing by hosting or third parties. This guide supplies no anonymity or retention guarantee.
Limits of this page
This page describes this guide’s own demonstration. It does not verify an outside Melolo operator, licence, official address, support service or data-handling policy. The presence of an original game cannot establish those external facts.
Frequently asked questions
Does this guide verify an official Melolo service?
No. It explains its own browser demo. An outside operator, account or app remains unverified.
Does restoration add 1,000 coins?
No. When idle below 10 coins, it sets the balance to exactly 1,000 and retains stored fractional carry.
Can an unfinished round resume after a reload?
No. The captured stake stays deducted, and the unfinished round ends without refund or payout. The default stake is 20 and the default hazard count is 3.
