According to Statista, in 2024 Spain was among the top ten countries in Europe in terms of turnover in online gambling, with video slots being the most popular genre. Among the most interesting issues for players is the RTP indicator, which directly affects the frequency of winnings. The 1win website lists this parameter for each game, and a number of slots consistently show high return percentages of up to 98%.
What is RTP
RTP (Return to Player) is the average percentage of money that a machine returns to players over a long period of time. For example, a slot with an RTP of 96% will theoretically return 96€ from every 100€ placed in the game. But this is an average indicator – it does not guarantee specific wins, but reflects the behaviour of the machine in the long term.
On the 1 win website, the RTP value is displayed in the description of each game. This is especially important for players from Spain, where online gambling regulation requires transparency of gaming mechanisms.
It is important to understand: RTP is not the only criterion that affects the frequency of winning. There is also volatility, which shows how often and how much the slot pays. Low-volatility games pay often but little, while high volatility games pay rarely but potentially big. However, it is high RTP in combination with medium or low volatility that gives the most frequent wins.
Games with the Highest RTP on 1win
Players looking for stability and frequent payouts are more likely to choose slots with an RTP of 96.5 per cent and above. There are plenty of such slots on 1win, and here are the most popular among the Spanish audience:
- Blood Suckers (NetEnt) – RTP 98%. A cult game with gothic surroundings, a bonus game “Vampire Hunt” and frequent payouts even on low symbols. Characterised by low volatility, so wins occur almost every 3-5 spins.
- White Rabbit Megaways (Big Time Gaming) – RTP 97.7%. An innovative slot with a reel expansion feature and an inbuilt bonus round with free spins. Despite the higher volatility, the frequency of bonus triggers makes the game profitable in the long run.
- Starmania (NextGen) – RTP 97.87%. Visually bright and intuitive slot with a fixed 10-line structure. Winnings here are frequent, especially in freespins, where additional wilds are added.
- Jackpot 6000 (NetEnt) – RTP up to 98.9%. One of the few slots where RTP depends on the player’s strategy. In Supermeter mode with proper bankroll management you can achieve maximum return. Spanish users who prefer old-school mechanics actively use this slot.
But even a high RTP doesn’t rule out losing sessions – it’s a matter of probability, not a guarantee.
How to Find Out and Compare RTP on 1win
At 1win, information about RTP and volatility is available in the game description section, which can be opened directly from the slot card. This is convenient: no need to look for data on external sites or study forums.
The operator provides several useful features:
- Filter by provider. For example, if you prefer games from NetEnt, where the average RTP is above 96.5%, you can filter the catalogue at once.
- Search by title. Just enter “high RTP” or a specific title and you will get a list of relevant games.
- Favourites. A player can add slots with high RTP to his personal list and return to them quickly.
- Betting history. Full statistics is available in the profile section: how much was bet, how much was returned – it helps to analyse the real RTP in practice, comparing it with the theoretical one.
This transparency is particularly appreciated by Spanish players who follow the principles of responsible gaming and analyse their gaming activity.
Which Games are More Likely to Produce Wins, Even If the RTP is Lower
Sometimes slots with a slightly lower RTP – say 95-96% – can show frequent wins due to low volatility or lots of bonus features. At 1win, this is particularly noticeable in the following games:
- Twin Spin (NetEnt) – although the RTP is 96.55%, almost every second spin brings payouts thanks to the twin reels.
- Reactoonz (Play’n GO) – RTP 96.51%, but the high frequency of cascading wins and occasional wilds create a sense of continuous play.
- Big Bass Bonanza (Pragmatic Play) – RTP 96.71%, the fishermen bonus game is often activated, especially during long sessions.
- Book of Dead (Play’n GO) is an iconic slot with an RTP of 96.21%. Despite the average volatility, combinations from the “Richie” symbol fall out more often than it seems, especially in the bonus game.
In fact, don’t just focus on RTP – it’s also important to consider the style of play, frequency of bonuses and mechanics of the machine. Some slots are specially set up to give out a lot of small wins, which creates a feeling of “playing on the plus side”, even if mathematically the RTP is a bit lower.
Why Spanish Players Love Slots with Frequent Payouts
In Spain, a large percentage of players prefer low-risk scenarios, especially in regions with high competition in the betting segment, such as Valencia and Andalusia. Here, players make short playing sessions, preferring to see the result immediately.
1win takes this behaviour into account: it offers “frequently winning games” picks, adapts recommendations based on user behaviour and even offers promotions on slots with high RTPs – for example, a 10% refund on what you lose every Friday for a month.
Slots with high win rates are also more often used in the mobile version, as they do not require long concentration or strong graphical acceleration. A player can make 10-15 spins in between and see at least partial results.
