Immortal Romance vs Blood Suckers

Immortal Romance vs Blood Suckers: the specs side by side

On the surface these are twin games: five reels, three rows, a gothic setting and vampires on the symbols. Underneath, they were built for different players. Blood Suckers, released by NetEnt in November 2013, is one of the highest-RTP slots in our checked data. Immortal Romance, now supplied by Games Global, gives up some of that return in exchange for a far higher ceiling. This page is part of our slot comparisons.

Two vampire slots built on opposite maths

Every slot divides its return between many small wins and a few large ones. Blood Suckers puts more of its 98% into the small and medium end, which is what low volatility means: the balance tends to drift rather than lurch. Immortal Romance holds more of its return back for rare, larger results, mainly inside its bonus levels, so long runs of small or no wins are a normal part of how it behaves. Our page on slot machine volatility shows how studios describe this spread.

The ceiling tells the same story from the other end. A 1,014x top prize means Blood Suckers has very little room for extreme outcomes. A 12,150x ceiling means Immortal Romance's maths model has to keep a share of the RTP for outcomes most players will never reach, and that share comes out of everyday returns. Neither design is fairer; they are different products with the same purpose of entertaining at a cost.

How Blood Suckers works: lines, free spins and the coffin bonus

Blood Suckers pays along 25 paylines from the leftmost reel. Its features are few and easy to follow:

• Wild: substitutes for ordinary pay symbols to complete line wins.
• Free spins: three or more scatter symbols start a free spins round in which wins are tripled; more scatters during the round can add spins.
• Bonus game: three or more bonus symbols on an active line from the first reel open a pick-style round. You choose coffins and stake the vampires inside for prizes until the round ends, the same idea as our pick me bonus page describes.

The help screen lists the exact number of free spins and the prize ranges in the coffin round for the version you open. Because the game's features are modest by modern standards, most of its 98% return is delivered through regular line wins, which is part of why it plays so smoothly.

How Immortal Romance works: 243 ways and the Chamber of Spins

Immortal Romance drops lines for 243 ways, so matching symbols on adjacent reels from the left pay in any row. Its wild (the game logo) substitutes and doubles wins it helps form. In the base game, Wild Desire can turn up to five reels wild at random, the slot's main route to a large win outside the bonus.

Three or more lion door-knocker scatters open the Chamber of Spins. Like a loyalty ladder, it adds characters as you trigger it more times on the same account:

The spin counts and multipliers for each character are listed in the help screen. The progression idea will be familiar if you know Thunderstruck II; our Thunderstruck vs Thunderstruck II comparison covers that game's version of the ladder.

98% vs 96.86% RTP: what the gap is worth in pounds

An RTP gap of 1.14 percentage points sounds small. In pounds, it means Immortal Romance's average cost is about 57% higher than Blood Suckers' for the same amount staked (£3.14 against £2 per £100). The table shows the long-run averages for 100 spins.

Those are averages over a huge number of spins. One 100-spin session on Immortal Romance could cost the full amount staked or return more, and Blood Suckers can lose a whole session's budget too. What the RTP does tell you is how much the game costs to play in the long run, which is the honest basis for comparing them. The high RTP slot machines page lists other games at the top of the range.

Max win at UK stakes: Blood Suckers vs Immortal Romance

Here is what each game's listed ceiling means at the stakes allowed in Great Britain. From 9 April 2025 the limit is £5 a spin for players aged 25 and over, and from 21 May 2025 it is £2 for players aged 18 to 24, as the government's announcement of the online slot stake limits (opens in a new tab) explains.

A ceiling is the most a single spin or feature can pay, not a prize anyone should expect. The bigger figure for Immortal Romance comes with more volatility, so most sessions will end nowhere near either number. Our max win caps page explains how studios set and enforce the limit.

How a £20 session tends to differ on each slot

Take £20 at 20p a spin: 100 spins on either game, lasting at least four minutes and ten seconds because of the 2.5-second minimum spin time. On Blood Suckers, the low volatility means the balance is more likely to move in small steps, topped up by frequent line wins and the occasional free spins round. Running out early is less common, but the 98% RTP still means the average session ends below where it started.

On Immortal Romance, the same £20 is more likely to fall steadily between features, with the session's outcome often decided by whether the Chamber of Spins or Wild Desire lands and how well it pays. Some sessions end well ahead; more end behind. That is not a judgement on quality, just what medium-high volatility looks like in practice. The maths behind this spread is explained on our standard deviation page.

Is the higher RTP slot always the better choice?

Not automatically. A higher RTP is better for anyone who measures value by how long their money lasts on average. A higher ceiling matters to players who accept a higher cost for the chance of a rarer, larger result. Both are legitimate preferences, provided the spend is affordable. Our answer to whether high RTP slots are better works through the trade-off with more examples.

What a higher RTP doesn't do is make winning likely. At 98%, the game still keeps £2 of every £100 staked over the long run, and most individual sessions end with a loss. Treat the RTP as a price tag rather than a promise.

UK rules that apply to both vampire slots

From 31 October 2021, British versions of online slots lost autoplay, turbo and slam-stop, gained a 2.5-second minimum spin time, and stopped celebrating returns that don't beat the stake. The background is in the Gambling Commission's 2021 online games design consultation response (opens in a new tab). Our slot game design rules page lists each change.

• Neither game offers a bonus buy in Great Britain; you reach free spins and bonus rounds only through the reels.
• RTP and rules must be available in the game; the casino's version may use a different RTP setting from the figures above.
• Your net position in the session must stay visible, which is useful on a medium-high volatility game where wins and losses swing.

Blood Suckers and Immortal Romance myths

'At 98%, I'll get £98 back from £100.' Not in one session. The RTP is an average across millions of spins; your £100 could last a short time or a long one, and you could end with nothing or with more.

'Immortal Romance is due a Wild Desire.' The random number generator decides each spin independently, so no amount of play makes a feature due. The guide to loose and tight slot machines explains why 'hot' and 'cold' machines are an illusion.

'Reaching Sarah's level makes the game pay more.' The 96.86% figure already covers every level. Opening more characters gives you more choice, not a better long-run return.

Immortal Romance or Blood Suckers: which suits you?

Both games have sequels on this site if you like the theme: Blood Suckers II and Immortal Romance II. Check each sequel's own RTP and volatility rather than assuming they match the originals.

How to compare the two slots yourself before staking

1. Open each game's help screen and confirm the RTP figure for that casino's version.
2. Read the paytable at your intended stake, so symbol values show in pounds.
3. Work out your cost per 100 spins: stake x 100 x (100% minus RTP).
4. Look at the max win in the rules and multiply by your stake to see the real ceiling.
5. Set a deposit limit and a session time before playing either game.

Our guide on how to compare slots adds a checklist you can use on any pair of games.
