Near-zero RTPs, rigged RNGs, impossible bonus triggers—and games that never pay. We reveal the slot sites to avoid at all costs.
Meet the Worst Slots →If you think all slots are created equal, think again. We’ve sifted through thousands of game rules to find the absolute bottom feeders:
RTP: All of these slots feature very low RTPs, with Fortunes of Olympus standing out for its catastrophic RTP of only 50%.
Design: The older slots (Atlantis, Ancient China, and Fortunes of Olympus) have less visually appealing designs and lack features expected from modern games. Shark Frenzy, while still not ideal, offers better graphics and a more engaging underwater theme.
Slot Age: Older slots (2010s and earlier) suffer from outdated design and fewer features. Shark Frenzy is the newest game here, though still problematic due to its low RTP.
Max Multiplier: Shark Frenzy has the highest max multiplier (100x), which could potentially offer larger payouts, but the low RTP still dampens its appeal.
These factors make these slots less desirable choices for players seeking higher payouts, better design, and a more engaging experience.

Return To Player—percentage of all stakes a slot pays back over time. Lower RTP means fewer winnings for you.
Licensed games should be fair, but some shady providers falsify or never audit RNGs. We test where we can.
Short expiry windows and hidden expiry clauses ensure most players never activate or use their freebies.
