Gems Bonanza by Pragmatic Play
On paper, Gems Bonanza sounds exciting. A colourful grid slot packed with modifiers like wild gems, squares, colossal symbols, and a nuclear feature that clears the board for fresh wins. But there’s a catch. The nuclear modifier gets used just to kick off the bonus round. That’s right. Instead of starting the bonus with a new board, it uses up one of your special features just to get things moving. It’s like eating half your dessert while serving it. The result? A feeling of wasted potential and a feature that feels more like a penalty than a bonus.
Ghostbusters Plus by IGT
Ghostbusters Plus had all the makings of a crowd-pleaser. Nostalgia played a big part and there were wilds with special powers, ghost-catching mechanics. It should’ve been a hit. But then, the expanding wilds came in… and placed themselves in the worst spots imaginable. The game chooses the position of the wild before it expands, meaning it often sits in a useless corner, expanding into empty space. The kicker? Even a rare all-direction wild can place itself in the bottom corner, wasting the bonus and frustrating players.
Yeti Battle of Greenhat Peak by Thunderkick
This one’s guilty of breaking a core rule of slot logic. Most games reward wilds as their own symbol, sometimes even with the biggest payouts. Not here. Stack four wilds and land a single “J” on the end? You only get paid for the J. No premium win. No wild line. Why? Because the game only pays the longest line, not the best-paying one. For players, it’s a baffling rule that often leaves wins feeling way smaller than they should.
4 Horsemen by Spinomenal
This slot suffers from a deadly combo: low RTP and high volatility. Translation? Long, dry spells with next to nothing in return. Players wait and wait, spin after spin, hoping for something big but often walk away with pocket change or nothing at all. It’s not broken, but it’s the kind of grind that can turn entertainment into frustration pretty quickly.
Seven Seven Xmas by Swintt
A festive theme doesn’t save this one. Like 4 Horsemen, it’s high volatility with very little in the way of meaningful wins. It’s one of those games where a bonus might come once in a blue moon. When it does, it fizzles out with small, underwhelming rewards. For many, it’s just not worth the wait.
Not every slot can be a hit but these five titles consistently rub players the wrong way. The mechanics just don’t make sense, and they’ve earned their place on the “worst of” list.
