Adult use and time boundaries
This guide and simulator are for adults aged eighteen or older. That is this website rule, not a determination of gambling eligibility, regional availability or local authorisation. Jurisdiction-specific questions require an authoritative local source.
Choose a stopping time outside the game, take breaks and leave when the time arrives. A free refill is optional, not an obligation to continue. If play crowds out other activities or feels difficult to stop, seek qualified local support; no diagnosis, symptom threshold or treatment claim is supplied here.
Stop future launches without chasing results
Stop cancels future automatic launches while active results settle under their captured settings. Closing the page ends participation. A virtual result creates no obligation to recover an earlier wallet balance.
Increasing stake scales debit and possible credit without raising expected return per coin. Mode changes do not raise positive-score frequency for a fixed probability condition. Choose a stopping time independently of the last result.
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.
What do the weighting modes change?
Low, Medium and High apply square-root, identity and square weights to a positive raw score. Zero stays zero, and each mode is separately normalised.
What does 96% describe?
Exact expected gross virtual return relative to captured stake under the stated probability condition. It is not a win probability or session guarantee.
