Scope of this independent guide
viv55.info publishes editorial pages and its own Max Rectangle browser simulator. A matching name or search query establishes no outside operator, official domain, licence, app, commercial catalogue, support contact or regional availability.
The simulator uses free virtual coins with no cash value. There are no deposits, withdrawals, commercial accounts or prizes here. Its results establish no external game mathematics, financial safety or commercial affiliation.
The actual simulator rules
One spin draws twelve independent fair open/closed cells in a three-by-four board. Raw score is the area of the largest all-open axis-aligned rectangle, if that area is at least three; otherwise it is zero. Count one maximum area, without summing rectangles. One whole stake covers the board.
These are this guide's original rules. Visual resemblance, game-category names and search snippets provide no evidence about an external commercial game.
Worked scoring examples
A completely open board scores twelve. One completely open row scores four. Just two adjacent open cells score zero. A rectangle may span several rows and columns, but every cell inside it must be open.
Exact expected gross return
Enumerate all 4096 equally likely outcomes and calculate a separate exact mean for each weighting mode. Choose Low, Medium or High before a round. Positive raw scores receive square-root, identity or square weighting respectively; zero remains zero.
Gross virtual credit equals the whole captured stake times 0.96 times observed weight divided by the corresponding exact mean. Every mode has 96% exact expected gross return. There are no separately paid row shares. The stake was deducted at launch, so gross credit includes the stake component and is not net profit.
Modes preserve positive-score frequency while changing positive credits after normalisation. The expectation is neither a 96% chance of winning nor a session-balance guarantee. Past results do not make a favourable next outcome due.
Captured settings and the persisted wallet
A new browser wallet starts with 1,000 free virtual coins. Settled balance and fractional-credit carry persist in localStorage. Reload does not replenish settled funds; clearing cache may leave localStorage intact. Fractions accumulate before whole coins are credited.
A spin captures one whole stake and mode. Controls and refill lock during settlement and an active automatic queue. Auto launches at most ten rounds; Stop cancels future launches while active results settle. Refill remains locked until all active results and queued launches finish. Optional manual refill is available while idle with balance below ten; it sets balance to 1,000 and preserves carry. It is not automatic and does not add 1,000.
Frequently asked questions
Is this an authenticated operator website?
No. This guide provides its own simulator and authenticates no outside commercial affiliation.
How is raw score defined?
One spin draws twelve independent fair open/closed cells in a three-by-four board. Raw score is the area of the largest all-open axis-aligned rectangle, if that area is at least three; otherwise it is zero. Count one maximum area, without summing rectangles. One whole stake covers the board.
What is an example of the score?
A completely open board scores twelve. One completely open row scores four. Just two adjacent open cells score zero. A rectangle may span several rows and columns, but every cell inside it must be open.
