The Island Register simulator is an original browser game with free virtual coins and no cash redemption. Its mathematical checks describe this demo only. They do not verify an outside product or its safety.
Browser play without an APK
This demo runs in the browser and supplies no APK installer, app update service or installation instructions. An outside file named JinJinJin is not established as an official package by this guide. There is no verified package signature or publisher record here.
A matching filename, HTTPS page, scan result or claimed signature is not proof of a package’s identity or safety. No installation is needed to read the rules or try the original virtual-coin demo.

Three rows, four columns and side-connected groups
Twelve independent fair bits fill a board with three rows and four columns, in row-major order. One is occupied and zero is empty. One complete hidden board is sampled at the start and revealed automatically, one cell per step. You do not choose a cell or relocate occupied cells.
Terminal reward is the number of occupied groups connected by shared sides. Diagonals do not connect. Count groups, not occupied cells. An empty board rewards zero. A later occupied cell can join formerly separate groups, so more revealed occupied cells need not mean a higher reward or quote.
Manual collection and attainable Auto limits
Before starting, choose stake 10, 20, 50 or 100 and Manual or Auto threshold 1.2×, 1.5×, 2×, 3× or 5×. One stake and those settings are captured. Settings and refill lock while active. Reduced motion changes animation timing only. Auto is a collection threshold, not repeated play.
Every due reveal is processed in order. Manual Collect first advances to the current timestamp; an earlier Auto crossing pays its full actual quote before later events. If zero comes before a crossing, the round loses. The maximum quote is about 2.733485×, so Auto 3× and 5× cannot trigger; they wait for final automatic settlement.
Manual refill below ten coins
A new local wallet starts at 1,000 free coins. The balance and fractional payout carry are stored in this browser’s localStorage. Whole coins are credited from each payout while its fractional remainder carries forward. They have no cash value.
Refill is manual and available only while idle with a balance below 10. It sets the balance to 1,000 rather than adding 1,000, and preserves fractional carry. It is neither a timed refill nor a reset available during a round. No promo code or deposit is involved.
Local storage and network requests
LocalStorage holds the demo balance and fractional carry. The page also makes network requests for Google Fonts and Statinside analytics, and its server can receive request information such as IP address and browser details. A local wallet does not mean all activity stays on this device.

Frequently asked questions
Does the name establish an outside publisher?
Zbaj is a search reference in this independent guide. It does not establish a verified gaming publisher, official domain, licence, app, account service or payment feature. No outside company or distribution channel is confirmed here. The Island Register simulator is an original browser game with free virtual coins and no cash redemption.

How are the occupied groups counted?
Twelve independent fair bits fill a board with three rows and four columns, in row-major order. One is occupied and zero is empty. One complete hidden board is sampled at the start and revealed automatically, one cell per step. You do not choose a cell or relocate occupied cells. Terminal reward is the number of occupied groups connected by shared sides. Diagonals do not connect. Count groups, not occupied cells. An empty board rewards zero. A later occupied cell can join formerly separate groups, so more revealed occupied cells need not mean a higher reward or quote.
How is the current quote priced?
Over all 4,096 equally likely boards, the initial mean reward is 2.129150390625. The quote is 0.97 × exact conditional expected terminal group count / that mean. It includes every possible hidden suffix and may rise or fall. It is not simply the current visible group count times a factor. The expected gross return is 97% for policies based only on revealed information in this fair model, not a 97% win probability or a guaranteed session return. Zero ends immediately; a positive quote after cell twelve settles automatically. The complete empty board is the only zero-reward board. Gross returns include returned stake; no second 3% factor is applied.
Can a new occupied cell join groups?
An empty board has reward zero. A completely occupied board has reward one because all cells connect. A checkerboard starting with occupied A1 has six isolated occupied groups, since only diagonal neighbours meet. It rewards six. In all 4,096 boards, group counts 0 through 6 occur 1, 1,126, 1,642, 1,038, 250, 37 and 2 times. With A2 and B1 occupied but B2 not yet revealed, two visible groups are separate. Occupied B2 connects them into one. Future cells still enter the conditional quote.
Can every Auto threshold trigger?
Before starting, choose stake 10, 20, 50 or 100 and Manual or Auto threshold 1.2×, 1.5×, 2×, 3× or 5×. One stake and those settings are captured. Settings and refill lock while active. Reduced motion changes animation timing only. Auto is a collection threshold, not repeated play. Every due reveal is processed in order. Manual Collect first advances to the current timestamp; an earlier Auto crossing pays its full actual quote before later events. If zero comes before a crossing, the round loses. The maximum quote is about 2.733485×, so Auto 3× and 5× cannot trigger; they wait for final automatic settlement.
