Sun20 APK Queries: Use This Browser Demo

The official website of sun20. This guide supplies a browser demo rather than an app download. You can use the game on its page without installing a package or signing in.

Open the game in the browser

The home page contains Divisor Variance Reels. No installation or sideloading is required for this demo. The guide does not supply or verify an official Sun20 app, APK or app-store listing. A similarly named package does not establish a relationship with this site.

Choose before spinning

Choose a stake of 10, 20, 50 or 100 virtual coins and a reward curve: Linear, Square or Cube. The defaults are stake 20 and Linear. For score s, the curve weights are s, s² and s³ respectively. Starting deducts one stake for both reels. Stake, curve, restoration and another start are locked until settlement; sound remains available. There is no interim collection or automatic sequence of spins. Settlement keeps your chosen stake and curve.

Use every positive divisor

List all positive divisors of n, including 1 and n itself, and let k be the number of divisors. Calculate k × the sum of their squares − the square of their sum. The minimum across the 256 starting integers is 0, so the reward score equals this statistic. It also equals the sum of squared differences over all unordered pairs of divisors. The game does not divide by k or k²: its score is not a normalized statistical variance. No proper-divisor chain or repeated replacement is involved.

Local wallet and manual restoration

A fresh wallet starts with 1,000 virtual coins. The balance, including zero, and fractional carry are saved in browser localStorage. When no round is active and the balance is below 10, Restore balance sets it to exactly 1,000. It does not add 1,000 or run automatically. Restoration preserves carry, the selected stake and the selected curve. It is available whenever those conditions are met. Coins have no cash value and cannot be withdrawn.

Reloading an unfinished spin

Reloading during a spin leaves the captured stake deducted. The unfinished round ends without refund, payout, continuation or resume. The remaining saved balance and existing carry remain local. Controls return to stake 20 and Linear, and a new spin still needs enough balance for its chosen stake. Ordinary settlement and balance restoration do not reset those settings. Reloading is not a way to recover the stake or complete a round.

Storage and external page requests

The game saves its virtual balance and fractional carry in browser localStorage. Pages load Google Fonts stylesheets and font files and include a Statinside visitor counter. These observations do not establish complete provider processing, server logging, retention or data-sharing practices. Playing without an account does not establish anonymity. Cached files and localStorage are separate; clearing only the cache may leave saved wallet values intact.

Frequently asked questions

Is an official APK supplied here?

No. The guide provides the browser demo and does not supply or verify an official app or APK.

Does restoration clear carry or reset settings?

No. While idle with a balance below 10, the manual control sets the balance to exactly 1,000 and preserves carry, stake and reward curve.

What happens if I reload during a spin?

The captured stake remains deducted and the unfinished round receives no refund or payout and cannot resume. Saved remaining balance and carry stay local; controls reset to stake 20 and Linear.
