Blood Hoppers Slot Review
A Magnifying Glass that hunts Fleas across the reels, burning them sticky and growing with every Scatter it finds: that’s the central idea powering Blood Hoppers, from 7Rings Gaming. It’s an unusual starting point for a slot, but the mechanic has genuine depth: three types of Flea Wilds each carry different multiplier values, and the Magnifying Glass turns them into locked assets for the remainder of the bonus round.
7Rings Gaming are a smaller provider, and Blood Hoppers shows the kind of focused design that tends to emerge when a studio builds around one distinctive idea rather than stacking features. The result is a high-volatility game with a 25,000x ceiling and a confirmed in-game RTP of 96.29% in its standard configuration. It’s aimed squarely at players who enjoy bonuses that build progressively, with the patience to let them develop.
Base Game & Features
Blood Hoppers runs on a 5×5 grid with 20 fixed paylines. The layout is standard enough, but the symbols populating it are anything but: the Flea Wilds are the defining presence on the reels, and the game’s visual identity leans into their cartoon horror-comedy aesthetic. The colour palette is bright, the animations are playful, and the whole thing has a slightly disgusting quality that’s more funny than off-putting.
Flea Wild Types
There are three distinct Flea Wild variants, each substituting for other symbols on winning paylines:
- Blue Flea: Standard Wild. No multiplier attached, but useful for completing paylines.
- Red Flea: Wild with a x2 multiplier applied to all winning lines it contributes to. The multiplier stays in place during the bonus round once the Flea is burned sticky.
- Black Flea: Wild with a x3 or higher multiplier on all winning lines. During the bonus, its value increases by x1 each time the Magnifying Glass revisits it, making it the highest-potential symbol in the game.
The visual differentiation between Flea types is clear in play; colours and animations make it easy to track which Fleas are active and what multiplier each is carrying. Once burned sticky during the bonus, Fleas change appearance so they’re distinguishable from new arrivals on the reels.
The Magnifying Glass
The Magnifying Glass is present in the base game as well as the bonus, landing on a random grid position each spin. When it lands on a Flea Wild during the bonus, it burns that Flea into a sticky position for the rest of the feature, and each subsequent visit by the Magnifying Glass to that same sticky Flea increases its multiplier by x1.
In the base game, its appearances are less transformative, but the Flea Wilds it highlights provide the occasional lift during otherwise quieter spins, particularly when a Red or Black Flea lands in a productive position.
Game Booster
The base game can feel relatively dry between Flea appearances, particularly during longer sessions without the bonus triggering. The Game Booster feature, available as a bonus buy option but also activatable during standard play, noticeably increases Scatter and Flea activity on the reels. With Game Booster running, the base game feels considerably busier and provides more frequent contact with the game’s core mechanics.
Blood Hoppers Bonus Features & Free Spins
The bonus game is triggered by landing three or more Scatter symbols. Three Scatters award seven Free Spins and start the Magnifying Glass at a 2×2 size. More Scatters at the trigger expand that starting size: four Scatters gives a 3×3 Magnifying Glass, and five Scatters or the Catch Em All purchase begins with a 4×4.
During the bonus, the Magnifying Glass lands on a random grid position each spin. Two outcomes are possible:
- If it lands on a Flea Wild, that Flea is burned sticky, locked in place for the remainder of the bonus. The Magnifying Glass revisiting that same sticky Flea on a later spin increases its multiplier by x1.
- If it lands on a Scatter, the Magnifying Glass grows by one unit in each dimension (2×2 becomes 3×3, and so on). At maximum 4×4 size, Scatter landings award +1 extra spin instead of further growth.
The progression loop is what gives the bonus its character. Early spins can pass with no Fleas caught, but as the Magnifying Glass grows and more Fleas accumulate as sticky Wilds, the feature builds genuine momentum. A bonus that starts quietly can finish strongly once multiple sticky Fleas are overlapping on winning lines simultaneously.
Bonus Buy Options
Blood Hoppers offers four bonus buy options, each with its own RTP variant:
- FS Booster 5x: Increases the chance of Scatter symbols landing by 5x. RTP: 96.42%.
- Game Booster: Boosts all features and Scatter frequency across the reels. Disables other buy options while active. RTP: 96.19%.
- Spot Shot: Guarantees three Scatters appear, launching the bonus with the Magnifying Glass starting at 2×2. RTP: 96.34%.
- Catch Em All: Guarantees four Scatters appear, launching the bonus with a 3×3 Magnifying Glass that can grow to 4×4 during play. RTP: 96.44%.
Of the direct bonus entries, Catch Em All is the more compelling purchase: the larger starting Magnifying Glass means the feature reaches its most developed state more quickly, giving it more room to build before the spins run out. Spot Shot delivers a standard-entry bonus that can produce average results, though outcomes vary considerably.
Leaderboard
An in-game Leaderboard displays stats across several time windows (10 minutes, one hour, 24 hours, seven days), with tabs for highest RTP games (Hot as Hell), lowest RTP games (Cold as Ice), most popular by sessions or bets, Game Winners for this title, and All Games Winners for the largest multipliers across the provider’s catalogue. It doesn’t affect gameplay outcomes; it’s a reference feature that can be tuned out entirely without any impact on the session.
Our Honest Verdict
Overall Rating: 7.0/10
7Rings Gaming have taken a familiar concept: sticky Wild multipliers building through a bonus round, and constructed a delivery mechanism around it that’s genuinely distinctive. The Magnifying Glass searching the grid, growing in size when it finds a Scatter, and permanently burning each Flea it catches into place gives the bonus a visible internal logic that games like Razor Shark and Tombstone RIP hint at but don’t quite replicate.
The base game is the honest limitation here. Flea appearances provide periodic interest, and Game Booster makes the session noticeably busier, but without it there are stretches where the reels offer little engagement. The bonus does the heavy lifting, and it earns that weight, particularly once the Magnifying Glass grows and multiple sticky Fleas start converging on the same winning lines.
The standout moment from testing was the Black Flea’s multiplier climbing from 4x to 5x after a second Magnifying Glass visit, then landing on the same winning line as the sticky Red Flea, the combination producing the session’s best natural bonus result. That kind of stacked multiplier moment is what the mechanic is built around, and it demonstrates why the bonus starts slowly but becomes considerably more exciting once the Magnifying Glass has grown and several Fleas are locked in.
The 96.29% RTP in its standard configuration is above average, with the Catch Em All variant nudging slightly higher at 96.44%. The 25,000x maximum win is a competitive ceiling that suits the high-volatility profile: strong rather than exceptional, but credible for what the mechanic can produce at its peak. Blood Hoppers suits high-volatility players who enjoy bonuses that develop through a visible progression, and who don’t mind a quieter base game in exchange for a bonus that rewards patience. Those who prefer frequent base game action or a defined max-multiplier floor should look elsewhere.
An unusual theme, a focused mechanic, and a bonus that earns its slow start. Blood Hoppers won’t convert everyone, but it delivers exactly what it promises.
