At 98.00% the house edge is 2% — a fifth of what a 90.04% build costs you. The catch is the configuration, not the maths: PlayOJO runs 90.04%.

NetEnt shipped Blood Suckers in November 2009 with one number on the front of the game sheet: 98.00%. The same sheet puts the hit frequency at 44.9% and caps a single free-spins pay line at 900× your stake.
Blood Suckers is an independent, hands-on review and guide from SlotsGamblers, written for UK players, with every figure checked against primary sources — the provider’s published game sheet, the operator’s own terms and the licence register — rather than operator marketing.
What the sheet cannot tell you is which build your casino loaded. A UK lobby replaces NetEnt's own bet range with the statutory £5 ceiling — £2 if you are 18 to 24 — so 900× is worth £4,500 at most on a spin. The RTP British sites publish for this game, checked on 2 August 2026, runs from 90.04% at PlayOJO to the full 98.00% at Mecca Bingo. The demo below runs on play money, no deposit and no registration.
Blood Suckers scores 7.8/10. The 98.00% return earns most of those points; the reduced British builds, the 0.5% free-spins trigger and one wagering exclusion take the rest back.
At 98.00% the house edge is 2% — a fifth of what a 90.04% build costs you. The catch is the configuration, not the maths: PlayOJO runs 90.04%.

Several UKGC licence holders carry the original game, but the return they run is not always the one NetEnt ships. The in-game help panel is where your lobby's figure sits.
Blood Suckers was drawn in 2009, before the genre settled on 3D renders, and that reads as an advantage: the reels sit in a stone crypt frame, and every symbol is a painted object, not a modelled one.
Nothing on screen fights the grid: the bite-mark wild and bride scatter register at a glance.
A slow church organ over a choral pad, mixed low enough that a paying line barely lifts it. The audio holds the room rather than staging drama — fitting for a game of small, frequent returns.
The free-spins cue is the one moment the mix opens up. On a British build a return below the stake cannot be celebrated.
Garlic, a crossbow, holy water and a bible fill the bottom of the paytable; vampires and a bride sit above. This is the hunter's version of the myth, not the romantic one.
Search results confuse the two, so: this is an original NetEnt slot with no film licence, and the identically named films — a 1971 British horror, a 2005 TV film, a 2021 German feature — are unrelated works.
This is what a 2% edge feels like from the chair: the balance drifts rather than drops, because 44.9% of spins return something and 65.7% of the return is paid in the base game.
The upside is just as gentle. NetEnt publishes no volatility rating here, so read the maths: a 900× single-line ceiling is modest, and the round reaching it appears on 0.5% of spins.
No autoplay, no turbo on a British licence, and a minimum 2.5 second game cycle: the pacing is set by regulation.
A sixteen-year-old slot survives in British lobbies because almost nothing since ships a 98.00% default. Players used it to stretch a bankroll, and operators noticed. That is how a title lands on an exclusion list.
So the score splits: strong on value and pacing, weaker on what surrounds it — a modest ceiling, rare features, and a return that depends on your lobby.
Play-money credits, no registration, no deposit, and the same mechanics: NetEnt's own HTML5 build on the 25 fixed paylines and published paytable, so wild, scatter and coffin bonus behave exactly as they do for money.
The free way to feel the rhythm. NetEnt publishes a 44.9% hit frequency, but only 0.5% of spins open the free-spins round and 2.1% reach the coffin bonus. British lobbies run manual spins only: no autoplay, no turbo, a 2.5-second minimum game cycle.
NetEnt publishes 98.00%, but British lobbies do not all serve it: on 29 July 2026 one Gambling Commission licensee published 90.04%, three published 98%. Every sum below runs on £100.
A 98.00% return is a 2.00% theoretical house edge: every £100 staked costs £2 long-run. NetEnt splits it, to one decimal, 65.7% base game, 11.0% free spins, 21.2% coffin bonus. Operator clients often print 97.99% — the same build, rounded.
It is not the only build. NetEnt's own Game Rules for Blood Suckers Touch™ state that the theoretical return to player for this game is 92.04%. British lobbies stretch it further: PlayOJO publishes 90.04% on its own GB page, Mecca Bingo and Lottoland UK 98.00%.
Those pounds are the price of ordinary cash play, not a promotion — no wagering or playthrough applies. And they are averages, not a session.
Each figure is published by the operator itself, on its own British game page or help panel. A blank means none.

The RTP field is one input of six. Run these before the deposit, in order — the third moves more money than the RTP field does.
Deposit £20 at Casumo: the 50% match adds £10, and since 19 January 2026 British wagering is capped at 10× the bonus — £100 of turnover. Fully weighted, that costs £2 on a 98.00% build and £9.96 on a 90.04% one. Same requirement, five times the price.
Open Game Rules or the help panel in the lobby you use and read the theoretical return to player line. No British rule forces an RTP figure inside the game: RTS 3C lets an operator publish the house edge, the return or the chance of winning, provided one is available before you bet.
5×3 reels, 25 fixed paylines, and two features that behave nothing alike: ten free spins carrying a 3× multiplier, or a coffin hunt that quietly returns more. Britain plays all of it by hand.
Three scatters anywhere pay 10 free spins at a 3× multiplier — won on the reels, not a bonus offer, so no wagering attaches to what they pay. Three bonus symbols in a row on an active line open the coffin hunt. NetEnt's game sheet rates the triggers at 0.5% and 2.1%. The return split is the surprise: base game 65.7%, free spins 11.0%, coffin round 21.2%. The less celebrated feature gives back the most.
Britain sets the tempo. RTS 14D has held a 2.5-second minimum game cycle since 31 October 2021, RTS 8A asks for a fresh commitment on every cycle, so autoplay is gone, and RTS 14E removes turbo, quick spin and slam stop. The maths is untouched; only the clock changes. Several hundred spins is real hours, which makes a bonus expiry date a harder limit than the money.
Blood Suckers 2, also NetEnt, publishes 96.94% and stops at 1,200×. Blood Suckers Megaways is a Red Tiger build claimed at 97.66% with a 20,521× ceiling — yet MrQ, licensed in Britain, states 92.77% on its own game page. If the 98% headline brought you here, the Megaways is not that game; for a higher published number, read our Book of 99 review.
£100 buys 400 spins of your own money at the 25p minimum, 100 at £1, or 50 at £2 — the 20,000-spin figure in the RTP section counts recycled returns too, before anything comes back. Set that against a 0.5% free-spins trigger: one round every 200 spins on average. At £1 a spin, £100 does not cover a single average wait. Seeing that round land twice takes a several-hundred-spin reserve, so the dry stretch is the plan, not a fault.
Same RNG, same maths, same configuration your operator account is served — the build lives at the casino, not on the handset. Blood Suckers Touch arrived in August 2014 and mirrors the desktop game one for one. The differences are interface: a portrait layout, a tighter frame around the reels, and the paytable moving into the mobile menu.
The art is 2009 and makes no apology for it: hand-drawn crypt walls, candlelight, eight themed payers plus a paying wild, the scatter and the bonus. Nothing has been remastered. What still lands is the sound — the organ swell as the third scatter drops, and the dry knock of hammer on stake through the coffin round. It reads as a period piece rather than a tired one.
Nine of the eleven symbols pay along a payline, one pays from anywhere on the screen, and one pays nothing at all but opens the coffin round. Coin figures are read at bet level 1, where a spin costs 25 coins.
Every figure comes from NetEnt’s own game sheet and the in-game rules panel, read on 2 August 2026. The 25 paylines are fixed, so one spin at bet level 1 costs 25 coins — and dividing any five-of-a-kind coin figure by 25 gives the stake multiple in the last column, which holds at every bet level and coin value.
The wild carries it alone. Five vampire bites on one payline pay 7,500 coins — 300× the stake, fifteen times the vampire lord behind it. That row also validates the table: 7,500 coins at bet level 4 is 30,000 coins, exactly the main-game single-line maximum NetEnt publishes. The wild substitutes for everything except the scatter and the bonus symbol.
The bottom of the table is where the game earns its reputation. There are no royals — no ace, king, queen, jack or ten — because the low tier is garlic, a crossbow, a bible and a flask of holy water, paying 3× to 4× the stake for five in a row. Those symbols sit densely on the reels, which is why 44.9% of spins return something and 42.9 of those points are ordinary bet-line wins: small, frequent, and the reason a balance moves slowly in either direction.
The published 98.00% does not come back evenly. NetEnt’s game sheet splits it three ways, to one decimal: 65.7% through the base game, 21.2% through the coffin bonus, 11.0% through the free spins.
Three or more vampire brides anywhere on the screen award 10 free spins, and both bet-line and scatter wins inside them are tripled. The 3× multiplier stops at two doors: it does not apply to a coffin bonus won during the round, and it does not apply to extra free spins. Those retrigger normally — three more brides add another ten. It happens on 0.5% of spins. These are reel-won spins inside the game rather than a promotional offer, so no wagering requirement attaches to what they pay.
The multiplier rides on the base figures, so the free-spins ceilings are the base-game ones tripled: 300× becomes 900× on a single payline, and 338.2× — every coinciding line at once — becomes 1,014.6×. Both are NetEnt’s own numbers, from one sheet, answering different questions. Neither caps a whole round: the sheet states that a game round may pay more than the coinciding maximum, because a round can contain several spins.
The bonus symbol is a stake and hammer, and it does not scatter: three or more must land left to right on an active payline, one bonus per spin at most. You then open coffins, every vampire staked pays coins, and the first bat closes the round. The payout scales with the stake and with how many bonus symbols triggered it, to 812.8× the stake under the in-game rules. It arrives on 2.1% of spins and returns 21.2% of the RTP — nearly twice the free spins’ 11.0%.
At the £5 Great Britain stake ceiling those read £1,500 for a base-game line, £4,500 for the same line in free spins and £4,064 for a full coffin round. Treat them as arithmetic rather than forecasts: no operator, leaderboard or press report documents a Blood Suckers maximum win, and a 0.5% trigger rate says how seldom the tripled ceiling is even in play.
Paraphrased themes from public review threads, read 2 August 2026. Nobody is named; nothing quoted.
No percentage split is published: the record leans on one platform and predates the reduced-RTP builds.
Volatility is contested — most write-ups say low, one database says medium, NetEnt publishes none.
The dominant theme is endurance, not excitement: players use it to protect a bankroll or grind wagering. Near a 45% hit frequency, roughly every second spin pays.
The complaint is not the 3× multiplier. Two scatters land far more often than three, and five still award the same 10 free spins — NetEnt's 0.5% trigger frequency explains it.
The critical theme aims at the operator setting, not the game: reduced builds, plus exclusion from bonus play or a low weighting. Open the help panel and read the bonus terms first.

The like-for-like swap is 1429 Uncharted Seas. Same low-variance grind, a ceiling in the same region, and a UK figure MrQ publishes on its own site rather than one lifted from a datasheet. Book of 99 is the opposite trade: one fixed 99.00% build in every British lobby, no configuration lottery — bought with high variance.
The Megaways sequel is where the gap bites. Affiliate pages print 97.66% for it; MrQ, a Gambling Commission licensee, states 92.77% on its own site. If the 98% brought you here, that is not the title carrying it. White Rabbit trades a far bigger ceiling for a higher expected cost per spin; whether the highest RTP is automatically the best value is worked through in the payout-slots guide.
Every row holds a Gambling Commission licence and carries this game. Only two carry a tracked route; the other four are named, and their button points back to those two rather than to the operator.

The questions the desk answers most often, answered against NetEnt's own documents and the operators' own pages.
Who actually developed Blood Suckers?
NetEnt — today part of the Evolution group, and the same studio behind Starburst. Every figure here comes from NetEnt's own game sheet and rules document.
When was it released — I keep seeing 2013?
10 November 2009 on desktop; the mobile build, Blood Suckers Touch, arrived in August 2014. The 2013 is the 10-11-2009 date with a corrupted year, still repeated on several sites.
Can I play Blood Suckers free first?
Yes. The demo higher up this page runs the whole game — every symbol, both features, the same paytable — on play money. No registration, no deposit, no card details.
Which UK casinos actually carry it?
The table above is the list. Carriage is confirmed on the operators' own lobby pages at NetBet, Casumo, PlayOJO, Mecca Bingo, Lottoland UK and William Hill Vegas. Lobbies change, so search yours first.
Is there a jackpot attached to this game?
No — neither progressive nor fixed. Everything it pays comes from the paytable, the free spins and the coffin bonus. Nothing is siphoned off to feed a pooled prize, part of why the headline reads high.
What is the max win in pounds at the UK cap?
900× stake on one line per spin — £4,500 at the £5 UKGC cap. All coinciding lines inside a single free spin reach 1,014.6×, or £5,073. A round holds several spins, so it can settle higher.
Is there a Blood Suckers machine in UK betting shops?
Land-based availability is set separately from online, and cabinet line-ups differ venue by venue. Nothing here describes a shop machine; the venue's own game list is the only source.
Gambling is 18+ in Great Britain, and four controls sit in the same account menu at every GB-licensed site: a deposit limit, a reality check that interrupts play at an interval you choose, a time-out that locks the account, and self-exclusion. Set them before the first spin.
GAMSTOP is the self-exclusion that reaches the whole market at once. Enrolment has been a condition of every British online licence since 31 March 2020, so one registration keeps every UKGC-licensed operator out of reach.
If you would rather talk to someone, the National Gambling Helpline is free, confidential and open around the clock. Nothing in this game rewards playing longer: the 44.9% hit frequency is a rhythm the maths sets, not a sign.

Gambling is entertainment, not income. Compliance and responsible-gambling review by Andrew Murray, 29 July 2026.
Anchored to the questions Britain actually asks about slot RTP and wagering, taken from live search results, answered against this game's published figures rather than the marketing copy.
A five-reel, three-row NetEnt slot with 25 fixed paylines, released on 10 November 2009. Its draw is the published return of 98.00%, leaving a house edge of just 2.00%. Two features: ten free spins at a 3× multiplier, and a coffin-opening vampire hunt. No jackpot, no gamble feature.
On many titles yes — studios ship several configurations and the operator chooses. Blood Suckers is the clearest British case: PlayOJO publishes 90.04% on its own GB page, Mecca Bingo publishes 98.00%, both read 2 August 2026. Same game, same regulator, a house edge of 2.00% or 9.96%.
Open the game's ⓘ information or help panel before the first spin. That figure binds your session, and what an operator prints there has to be true. A review or a database tells you what was shipped, not what your lobby runs. Check again whenever you switch site.
Below the market average — and on a game with a 98.00% reputation, a different economy altogether. Every £100 of turnover carries roughly £6 in expected cost at 94%, against £2 at 98.00%: triple the margin on identical reels. Britain's live spread here runs 90.04% to 98.00%.
You read the published hit frequency, not a pattern on the reels. Blood Suckers returns something on 44.9% of spins, close to one in two — why a modest balance lasts. The features are far rarer: free spins trigger on 0.5% of spins, the coffin bonus on 2.1%.
NetEnt's game sheet gives two labelled ceilings, which is why affiliate figures disagree. Max win per spin on a single line is 900× stake — £4,500 at Britain's £5 cap. All coinciding lines within one free spin reach 1,014.6×, or £5,073. A game round may hold several spins.
They are already inside it, never added on top. NetEnt splits the 98.00%, to one decimal, into 65.7% from the base game, 11.0% from free spins and 21.2% from the coffin bonus. That is why a rare trigger and a high headline sit together: two thirds of the return arrives spin by spin.
A bonus arrives with a turnover requirement attached: stake it a stated number of times before it can be withdrawn. Games do not all count the same — some contribute nothing. Mecca Bingo names Blood Suckers on its excluded list, so bonus funds cannot be turned over there.
It means a £20 bonus has to be staked £200 before the balance can be withdrawn. Since 19 January 2026 that is the British ceiling, not generosity: licence condition SR 5.1.1 caps bonus wagering at 10× the bonus and bans mixed-product promotions. Terms quoting 35× are out of date.
Yes where the offer says so, but the winnings usually land as bonus funds carrying that 10× turnover, a maximum-bet rule and an expiry date. Free spins are tied to a named title: NetBet's welcome spins run on Big Bass Splash, not on this game. Check which title first.
