Blood Suckers by NetEnt is one of the highest-RTP slots ever released to the public — a 97.66% RTP, low-medium volatility, and a max win of 7,500x your stake (via the bonus game). Vampire-themed, released in 2009, and still required reading for any SA player serious about finding value in online casino gameplay. The 97.66% RTP isn't a typo — and understanding why it matters for how you should use this game is the most important thing in this review.
How to Play Blood Suckers
Blood Suckers runs on a 5×3 reel grid with 25 fixed paylines paying left to right. The vampire Gothic aesthetic — Dracula, vampiresses, garlic, coffins, wooden stakes, and silver rings — sets the tone. It's a classically designed slot with no cluster pays, no Megaways, no Hold & Spin. Just high RTP, a bonus game, and free spins.

Feature Breakdown
Wilds
Standard wild substitution. The Blood Suckers logo wild appears on all reels and substitutes for all symbols except scatters and bonus symbols.
Free Spins — The Coffin Scatter
Land 3, 4, or 5 coffin scatter symbols anywhere on the reels:
- 3 scatters: 10 free spins with a 3x multiplier
- 4 scatters: 10 free spins with 3x multiplier (more scatters mainly add value via payout)
- 5 scatters: 10 free spins with 3x multiplier
During free spins, all wins are multiplied by 3x. The number of free spins stays at 10 regardless of scatter count — the extra scatter value is expressed in scatter payout rather than spin count. Free spins can be retriggered.
Vampire Slayer Bonus Game — The Big Win Feature
Land 3 or more bonus symbols (stakes/wooden stakes) on the reels to trigger the Vampire Slayer bonus game. This is a pick-and-click feature: you're presented with a room of coffins. Each coffin you open reveals a reward — either a coin prize or a sleeping vampire (which you stake for a larger prize). You continue opening coffins until you reveal a dead/open coffin that ends the feature.
This bonus game is where the 7,500x theoretical max win comes from — optimal picks across the coffin field produce the highest single-feature payout in the game. In practice, typical bonus game returns are more modest but meaningful.

This is the most important thing in the Blood Suckers review:
Blood Suckers has a 97.66% RTP by design. But many SA casinos do not offer the full 97.66% version. The game is frequently configured to a lower RTP (sometimes as low as 95%–96%) because it's expensive for casinos to run at the full rate. Before playing Blood Suckers for RTP value, you MUST check the game info panel and confirm you're getting the 97.66% version. If you're not, the game's primary selling point doesn't apply.
Bets & Max Win in Rands
| Setting | Amount |
|---|---|
| Minimum Bet | R0.25 per spin |
| Maximum Bet | R500 per spin |
| Max Win | 7,500x (bonus game) |
| Max Win at R10/spin | R75,000 |
| Max Win at R25/spin | R187,500 |
The 7,500x is a theoretical max from the Vampire Slayer bonus game with perfect picks. Realistic bonus game returns are typically in the range of 20x–200x your bet depending on the pick sequence.
Myth-Busting
"Blood Suckers has 97.66% RTP everywhere — I just need to play it anywhere." False — and this is the most important myth to debunk. Casinos can and routinely do configure Blood Suckers at lower RTP settings. The 97.66% RTP is the NetEnt default; the casino-deployed version may be significantly lower. Always check.
"High RTP means you'll win more often." High RTP means you lose money more slowly, on average, over many spins. It does not mean individual sessions will be profitable. You can still have a losing session on a 97.66% RTP game — especially on a short session where variance plays a role.
"Playing Blood Suckers is a guaranteed winning strategy." No slot is a guaranteed winner. 97.66% RTP means the casino retains 2.34 cents per rand wagered on average. You will lose money over infinite play. The advantage of high RTP is lower long-term loss rate, not guaranteed profit.
"The bonus game is rigged to never give the best picks." The Vampire Slayer bonus is a random pick event. The coffin positions are randomly assigned by the RNG when the feature triggers. You cannot influence or predict which coffins contain better rewards.
Strategy & Tips
Blood Suckers is most valuable as part of a responsible gambling strategy focused on minimising expected losses while still enjoying real money play.
RTP-Focused Bankroll Strategy
If you've confirmed you're playing the 97.66% version: a R1,000 session at R10/spin with 100 spins has an expected loss of R23.40 (2.34% × R1,000). Compared to a 96% RTP slot where the expected loss is R40, you save R16.60 on the same session. At higher session volumes the difference is meaningful.
Bankroll Sizing
| Bankroll | Recommended Bet | Expected Spins |
|---|---|---|
| R50 | R0.50 | ~100 spins |
| R200 | R2.00 | ~100 spins |
| R500 | R5.00 | ~100 spins |
| R1,000 | R10.00 | ~100 spins |
Bonus Wagering Consideration
Blood Suckers' high RTP makes it less attractive to casinos for bonus play, and many casinos specifically exclude Blood Suckers from qualifying games for wagering requirement purposes. Check your casino's bonus terms before playing Blood Suckers with bonus funds.
Stop-Loss
70% of session bankroll — low-medium variance means a more lenient threshold is reasonable.
Mobile Experience
Blood Suckers is an older NetEnt title that has been HTML5-converted and plays adequately on mobile.
Android: Functional. The graphics show their age on high-resolution screens — pixels are visible on modern OLED displays. The bonus game pick-and-click feature works on touchscreen.
iOS: Works on Safari. No performance issues, though the dated visuals are more obvious on iPhone Retina displays.
Orientation: Landscape preferred.
Data usage: Very light by modern standards.
Graphics & Sound
Blood Suckers was visually impressive in 2009. In 2026 it looks its age.
Visuals: Classic vampire Gothic imagery — detailed for its era, noticeably dated today. The character symbols have a painted aesthetic that has charm but not the polish of modern slots. The Vampire Slayer bonus game is presented in a darkly atmospheric room that still feels thematic.
Sound: Gothic ambient music with organ notes. Atmospheric and appropriate. The bonus game has distinct audio feedback when you open a coffin.
Overall production quality: 5.5/10 by 2026 standards. 8/10 for its era. The dated visuals are the trade-off for a historically significant game with an industry-leading RTP.

FAQ
What is the RTP of Blood Suckers? The default RTP is 97.66% — one of the highest RTP slots ever commercially released. However, many SA casinos configure it at a lower rate. Always check the game info panel to confirm which version you're playing.
Is 97.66% RTP available at South African online casinos? Some SA-facing casinos offer the full 97.66% version; others configure it lower. It varies by operator. This is why confirming the RTP in the game info panel before playing is critical for Blood Suckers specifically.
How does the Vampire Slayer bonus game work? Land 3+ bonus symbols to enter a coffin pick feature. Open coffins one by one to reveal prizes (coin wins or sleeping vampires you stake for bonus wins). The feature ends when you reveal an empty/open coffin.
What is the maximum win on Blood Suckers? 7,500x your stake — achievable via optimal picks in the Vampire Slayer bonus game. At R10/spin that's R75,000.
Why do some casinos exclude Blood Suckers from bonus play? High RTP games are expensive for casinos to offer as part of bonus-funded play. Wagering requirements become harder to meet when players are playing a 97.66% RTP game. Most casinos partially or fully restrict high-RTP games from bonus wagering.
Is Blood Suckers still worth playing in 2026? Yes — but only if the full 97.66% RTP is confirmed at your casino. It's a historically significant game with genuine strategic value for players prioritising loss minimisation.
Can I play Blood Suckers on mobile in South Africa? Yes. HTML5-based, plays in-browser. Visuals show their age on modern screens but gameplay is fully functional.
Does Blood Suckers have a bonus buy? No. It predates the bonus buy feature by over a decade.
Conclusion
Blood Suckers is the highest-RTP slot in this review series and one of the most strategically important games available to SA players — but only when played at the full 97.66% RTP version. If your casino is offering that, Blood Suckers is the best-value real money slot experience available, particularly for players who want to maximise their session length against their bankroll.
If the 97.66% version isn't available at your casino, the game loses its primary advantage and you should look elsewhere.
