Stopping between rounds

Take a break by choosing not to start another round. There is no pause control, timer, account blocking or self-exclusion tool. Wait for a round to settle before leaving if you want its return credited; leaving early loses that unfinished round while keeping its stake deducted. Restoring the virtual balance does not erase time spent or impose a spending restriction.

Integer credit, carry and restoration

Without a saved nonnegative balance the wallet starts at 1000 play coins. Settlement credits floor(stake × gross multiplier + stored fractional carry). The remaining fraction is saved for later rounds; a zero return leaves carry unchanged. Carry stays between 0 and 1 and persists across settlement, restoration and reload. Restore balance works manually while idle below 10 coins and sets the balance to exactly 1000, rather than adding 1000. It does not clear carry.

Exact expectation and sample limits

The exact expected raw gross return is 24/25, or 96% of the captured stake, in all three modes. It is neither a win probability nor a guaranteed session result. Across the 256 equally likely reel pairs, summing each mode’s weight gives its exact normalization. Saved source-matching simulations use one million rounds per mode and measured approximately 95.77%, 96.03% and 96.25%. These are sample observations, not the payout law. Persistent carry reconciles fractions over settlements; an individual integer credit can differ from raw return.

Stakes and settlement timing

Select stake 10, 20, 50 or 100 play coins; the default is 20 and linear weight. One start samples both reels and deducts one stake. Stake and mode controls, restoration and another start lock while busy; sound remains available. Normal animation settles after 500 milliseconds, subject to frame scheduling. With reduced motion it settles on the first animation frame. There is no intermediate collection, pause button, row bet, bonus feature or automatic round queue.

Local wallet and page reload

Balance, including zero, and fractional carry are saved in browser localStorage. Reloading or leaving an unfinished round discards it without refund, payout or continuation; the stake remains deducted. Reload restores stake 20 and linear mode, rather than previous selections. The wallet is local browser data, not an account synchronized across devices. Removing site data can remove it. Clearing cached files alone may leave localStorage intact; browser settings can affect persistence.
