🙋 FAQ
Are 10× or 50× buys always better value than supers?
They carry similar RTP but lower variance. If your goal is bankroll longevity or bonus wagering, low-cost buys win.
Which slot here has the best pure RTP?
San Quentin (100× tier) tops with 96.95 %, but among sub-50× buys, Big Bass titles lead at 96.71 %.
Do all casinos let you buy bonuses with promo funds?
Most MGA/Curacao sites do, provided the cost doesn’t exceed their max bet (often €5). Check T&Cs.
Is demo mode identical to cash play?
RNG and odds are identical, but confirm you’re on a 96 %+ build—some sites host lower RTP versions
Why include 60×–66× titles in a “cheapest” list?
They remain the lowest-cost entry for extreme variance (e.g., DOA 2) and illustrate the step up from true budget buys.
