100 Zombies

Low variance paired with a 0.20-to-1,000 stake range is the unusual combination here, and it points at one particular kind of player. slot.report puts the return at 96.03% and files variance as low, which registers as level 1 of 5 on our scale — the calmest reading we record.

Level-1 variance behind the Halloween symbols

Against the 96.08% median we derive from 9,226 games, 96.03% falls five hundredths short, a difference you would need millions of spins to notice. The distinction lies in the payout rhythm instead. Level 1 means small returns land often and the balance moves in short steps rather than cliffs, which is why the 5,000-fold spread between the stake ends matters: identical math scales from a 0.20 spin to a 1,000 one. Five reels, fixed paylines. Endorphina carries 230 titles in our index, and the mechanics record here is bare — no bonus buy, no progressive, no Megaways, no tumbling reels — with neither a release date nor a maximum win reaching our sources.

Halloween and Horror are the listed themes, yet the low-variance profile suits patient session players far more than jackpot chasers. Grinders will feel at home.
