39D Android APK: Browser Demo Guide

No Official APK Supplied

The queried name 39D is treated as an unverified identity. This guide does not provide, verify, or host an official Android APK file. The demo is a browser-based application that does not rely on a specific mobile operating system package. Users should not assume that a downloaded APK from an external source is the official version, as no verified app identity is established.

Browser-Based Demo Mechanics

The demo implements the euclidean remainder volume Claim game. It uses twelve independent fair binary steps to reveal three four-bit blocks. Each block is decoded as 0..15 and incremented to obtain integers a, b, and c (each 1..16). The raw terminal statistic is the product of (a modulo b), (b modulo c), and (c modulo a). The gross quote is 0.97 times the conditional expected terminal weight divided by the initial expected terminal weight. The score function is: The reward score is the product of the three division remainders, minus the global minimum zero.

Wallet and Persistence

The virtual wallet starts with a balance of 1000. Fractional carry persists in browser localStorage across settlement, refill, and reload. Restoration is manual and sets the balance to exactly 1000 when idle and below 10. Settled balances persist locally, including zero. Unfinished rounds end on reload without refund; the captured stake remains deducted. Controls default to a stake of 20 and the first preset upon reload.

Controls and Modes

Stakes are selectable at 10, 20, 50, or 100 play coins, with 20 as the default. Users choose linear, squared, or cubed reward weight before capturing a stake. Automatic collection can be set to off, 1.25, 1.75, or 2.50. Settings, restoration, and starting another round are locked while a round is active. An earlier crossed auto threshold settles before a later zero event; quote zero takes precedence at the same event.

Settlement and Evidence

At settlement, the floor of (raw gross return + stored fractional carry) is credited; the remainder persists. Zero-return rounds leave fractional carry unchanged. Simulation measurements support but do not promise the expected RTP of 97%. For example, under curve 0 with first-cross 1.75, the measured RTP was 97.06349297166128% with a standard error of 0.10526749311742645% over 1,000,000 rounds.

Privacy and Audience

The whole-coin wallet balance, including zero, and separate fractional carry persist in browser localStorage. Clearing cached files alone need not remove that storage. Reload restores stake 20, Linear and auto off; an interrupted captured stake is not refunded, paid or resumed.
