Blood Suckers Slot Review
Blood Suckers is a low volatility vampire-themed slot by NetEnt with an extraordinary RTP of 98.00%. Released in 2009, it remains one of the highest RTP slots ever produced, featuring a Pick & Click bonus game and Free Spins with a 3x multiplier for a maximum win of approximately 900x.
What is Blood Suckers?
Blood Suckers by NetEnt, released in 2009, occupies a unique position in the online slot landscape. With a 98.00% RTP, it stands as one of the highest-returning slots ever created by a major provider, and it has maintained that distinction for over 15 years. The game features a gothic vampire theme with symbols including garlic, holy water, crucifixes, crossbows, and vampire characters across a traditional 5-reel, 3-row layout with 25 fixed paylines. The visual design reflects its 2009 origins — the graphics are dated compared to modern releases, but the art direction maintains a coherent, atmospheric aesthetic. Blood Suckers earned its reputation not through flashy mechanics or extreme win potential but through raw mathematical generosity. The 98.00% RTP means the theoretical house edge is only 2%, which is roughly half of what most modern slots offer. This has made it a strategic favourite among players looking to clear wagering requirements on casino bonuses, a use case that has defined the slot's identity more than any design feature. NetEnt released Blood Suckers II in 2017 with updated graphics and a slightly lower 96.94% RTP, but the original continues to attract players specifically because of its unmatched return rate.
RTP, Volatility & Max Win
The 98.00% RTP of Blood Suckers is not just above average — it is in a category almost entirely its own among mainstream slot releases. The industry average hovers around 96%, meaning Blood Suckers returns roughly 2% more of every dollar wagered over time. To put this in perspective: on a slot with 96% RTP, you statistically lose $4 per $100 wagered; on Blood Suckers, you lose $2 per $100 wagered. Over extended play, this difference compounds significantly. A player wagering $10,000 total would expect to lose $200 on a standard slot versus $200 on Blood Suckers — half the theoretical cost. This mathematical profile is precisely why Blood Suckers became the go-to slot for bonus clearing. When a casino offers a $100 bonus with a 35x wagering requirement ($3,500 in total wagers needed), playing Blood Suckers means an expected loss of only $70 during clearing, compared to $140 on a 96% RTP slot. Many casinos have responded by excluding Blood Suckers from bonus play entirely, or weighting it at 50% or less toward wagering requirements. The low volatility further supports bonus clearing because it minimises the chance of burning through your bankroll before completing the required wagers. Players should always verify whether Blood Suckers is eligible for bonus play at their chosen casino before committing to this strategy.
How Blood Suckers Works
The base game uses a conventional 5-reel, 3-row layout with 25 fixed paylines paying left to right. The wild symbol (a vampire being staked) substitutes for all symbols except scatters and bonus symbols, and it pays the highest line win — five wilds on a payline deliver 1,000 coins. The paytable features thematic symbols ranked from playing card icons (lowest) through garlic, holy water, crucifixes, and crossbows to the vampire characters (highest regular symbols). The hit frequency is notably high at approximately 45%, meaning nearly half of all spins produce some return. Most of these wins are small relative to the bet, which is characteristic of low-volatility math models. The base game grind is steady and predictable rather than dramatic, which makes it well-suited for extended sessions.
Bonus Round & Free Spins
Landing three or more scatter symbols (the Blood Suckers game logo) anywhere on the reels triggers the Free Spins feature, awarding 10 free spins with a 3x multiplier applied to all wins. This means every winning combination during the free spins round pays triple its normal value. Additional scatters during free spins do not retrigger the feature. The 3x multiplier significantly boosts the value of any winning combinations that land, though the low volatility means individual free spin wins tend to be modest. The cumulative effect of 10 multiplied spins often produces returns in the 20x to 60x range, with occasional rounds reaching 80x or more when premium symbols align favourably. Free spins trigger approximately once every 80 to 120 spins in practice.
Special Features
The Pick & Click bonus game activates when three or more coffin bonus symbols appear on reels 1 through 3. Players are presented with a selection of coffins to open, each revealing a cash prize or a vampire to stake. The bonus continues until a specific number of coffins have been opened, with the total accumulated prize awarded at the end. This bonus tends to deliver between 15x and 50x the total bet, adding a layer of interactivity beyond standard reel spinning. The combination of the Pick & Click bonus and Free Spins means the game offers two distinct bonus triggers, which keeps the gameplay varied despite the conservative volatility profile. Neither bonus has a buy option — both must trigger naturally through symbol combinations.

Common Misconceptions
What Players Say About Blood Suckers
Blood Suckers maintains a devoted following built almost entirely on its mathematical profile. Community discussion consistently revolves around bonus clearing strategies rather than gameplay excitement — a testament to its niche identity. Players describe sessions as 'boring but profitable' and 'the accountant's slot,' phrases that would be criticism for any other game but serve as compliments here. Forum threads routinely calculate expected losses during wagering requirement completion, with Blood Suckers consistently topping the charts. The primary complaint from the community is the increasing number of casinos that have excluded it from bonus play, with players actively sharing lists of operators that still allow Blood Suckers for wagering. Newer players sometimes express disappointment at the dated graphics and modest win potential, but experienced players understand that the 98% RTP is the feature, not a side note.
Session Notes
Extended testing of Blood Suckers confirmed the steady, low-drama rhythm the math model is designed to produce. Over 500 spins at minimum stakes, the bankroll never deviated more than 30% from the starting balance in either direction. The hit frequency was noticeably high — winning spins came roughly every two to three spins, though the majority returned less than the bet amount. The Pick & Click bonus triggered three times across the session, returning 22x, 35x, and 41x respectively. Free spins triggered four times with returns of 18x, 27x, 45x, and 62x. No single event produced a dramatic win, which is exactly what the low-volatility profile predicts. The experience is best described as a slow, controlled grind — the opposite of the emotional rollercoaster that high-volatility slots deliver. For players whose goal is time at the reels with minimal bankroll erosion, Blood Suckers performs exactly as advertised.
Expert Assessment
Blood Suckers remains the benchmark for high-RTP slot design. The 98.00% return rate is virtually unmatched, and the low volatility ensures sessions are predictable and bankroll-friendly. The 900x maximum win and dated visuals are trade-offs, not flaws — this slot was designed for mathematical efficiency, and it delivers on that mandate better than any competitor. Essential knowledge for any player who takes bonus clearing seriously.
Is Blood Suckers Worth Playing?
Blood Suckers earns its legendary status through pure mathematics rather than spectacle. The 98.00% RTP remains virtually unmatched among major provider releases 15 years after launch, and the low volatility ensures that this generous return rate translates into steady, predictable sessions rather than feast-or-famine cycles. The graphics are dated, the maximum win of 900x is modest by any standard, and the gameplay lacks the cinematic drama of modern releases. None of that matters for its core audience. Players who approach Blood Suckers for what it is — a mathematically generous, low-risk slot designed for extended play — will find it delivers exactly on that promise. For bonus clearing where eligible, it remains the gold standard. For entertainment value and big-win potential, look elsewhere.
