Editorial analysis
The verdict the numbers support: a median-grade payout welded to a top-of-scale swing profile, which is a demanding pairing. The published 96.07% and the 96.08% midpoint we derive from 9,233 catalogued games are, for any practical purpose, the same number. The gap is negligible. Endorphina supplies the title from a shelf of 231 games in our records.
Five reels, fixed lines and a 900,000 payout ceiling
Top wins are capped in currency rather than in stake multiples: 900,000 is the absolute limit whatever you bet. Five reels, fixed paylines. slot.report rates the variance high and our own scale puts it at 5 of 5, so the distance between an average session and a good one runs wide. Nothing enlarges the grid — no Megaways, no cascading drops, no jackpot pool, no paid entry into the feature round.
A stake band from 0.01 to 5 keeps it within reach of small bankrolls, which is the sensible way to meet level-5 variance. Theme data is missing.
Behind the published 96.07% the operator's arithmetic keep is about 3.93%, spin after spin. Decide your limit early. 18+.
