When it comes to beating the wagering requirements at an online casino, the games you choose to play should be part of your slots strategy. You simply have to play the best slots for wagering. That is unless you get some free spins on no wagering slots, so you don’t have to worry about the wagering requirements at all.
Almost every experienced player will tell you that the best wager slots are NetEnt games. Yes, they have some great slots in their offer where you can win big, but they also have a lot of good low wagering slots where you can wager massive amounts of money without letting your balance drain by too much. The lineup below covers nine titles spanning NetEnt and Thunderkick, two studios with consistently high RTP figures and low-volatility math models that are well-suited to clearing wagering requirements without rapid bankroll erosion.
What Are the Best Slots for Wagering?
Here is a list of the best slots for wagering big bonus amounts. These will help you beat wagering requirements more often. Remember, these are good slots for wagering because they’re low volatility games with above-average RTP figures.

1. Starburst
- Provider: NetEnt
- RTP: 96.09%
- Volatility: Low
- Paylines: 10 (both ways)
- Best Feature: Starburst Wilds + Re-Spins
Starburst is the slot most casino veterans reach for first when they’re working through wagering requirements, and it earns that reputation for good reason. The 5-reel, 10-payline gem theme runs on a low-volatility math model where small-to-medium hits arrive frequently throughout most sessions. Wins pay both left-to-right and right-to-left, which doubles the effective payline count and pushes the hit frequency higher than the 10-line layout would suggest.
The Starburst Wild is the only feature, but it’s a well-designed one. When a wild lands on reels 2, 3, or 4, it expands to fill the entire reel and triggers up to two re-spins with the wild locked in place. Stacking wilds across multiple reels during the re-spin sequence is where the bigger session wins originate. The 96.09% RTP combined with low volatility means a typical 100-spin session at higher bets sees a 10-20% balance loss on average, with the occasional break-even or small-plus result. That predictable session math is exactly what makes Starburst the genre standard for clearing bonus wagering. Play Starburst at Casumo for the most direct UK-licensed access.
2. Koi Princess
- Provider: NetEnt
- RTP: 96.23%
- Volatility: Low
- Paylines: 20
- Best Feature: Four Random Bonus Features + Bonus Bet Toggle
Koi Princess sits firmly in NetEnt’s anime-inspired catalogue and remains one of the most feature-dense low-volatility slots in their portfolio. The 5-reel, 20-payline layout pairs koi fish, lotus flowers, and Japanese iconography with four randomly triggered base game features: a 5-Hit feature that pays a guaranteed five-of-a-kind win, a Random Wilds feature that drops 4-9 wilds onto the reels, a Wild Reels feature that turns 2-5 reels completely wild, and a Bonus Activation feature that forces one of the three main bonus rounds.
The reason this slot earns its place on a wagering list is the bonus frequency. Most low-volatility slots compensate for their gentle math with infrequent feature triggers, but Koi Princess delivers some kind of feature event within most 100-spin sessions, keeping bankrolls topped up between the bigger payouts. The Bonus Bet feature toggles a higher stake in exchange for theoretically improved bonus odds, but in practice the impact on hit rate is marginal. Running standard bets and letting the random feature triggers fire on their own is the more bankroll-efficient approach for clearing wagering requirements.
3. King of Slots
- Provider: NetEnt
- RTP: 96.95%
- Volatility: Low
- Paylines: 20
- Best Feature: Sticky Wins Re-Spin Mechanic
King of Slots earns one of the highest RTP figures in NetEnt’s mainstream catalogue at 96.95%, paired with a low-volatility math model that makes it a strong fit for any wagering session. The 5-reel, 20-payline classic Vegas theme runs across red 7s, BAR symbols, gold coins, and a King character set against a stage-curtain backdrop. The aesthetic is dated compared to NetEnt’s more recent releases, but the underlying maths holds up.
The Sticky Wins mechanic is the standout feature. Any winning combination triggers a re-spin where the winning symbols stay locked in place while the remaining reels respin at no additional cost. The re-spin chain continues as long as new symbols extend the winning combination. Most sessions on this slot see medium payouts every 10-20 spins on average, which makes balance erosion much slower than higher-volatility alternatives. The frequent low-to-medium wins keep the wagering counter ticking over without burning through bankroll. Play King of Slots at NetBet for one of the most consistent UK-licensed deployments.
4. Dazzle Me
- Provider: NetEnt
- RTP: 96.90%
- Volatility: Low-Medium
- Ways to Win: 76 (asymmetric reel layout)
- Best Feature: Linked Reels + Free Spins with 2x Multiplier
Dazzle Me runs on an asymmetric 5-reel layout with 3, 4, 5, 4, and 3 rows respectively, producing 76 ways to win across a single spin. The diamond and gemstone theme is set against a dark backdrop with neon accents, and the polished art direction is exactly what you’d expect from NetEnt’s mid-2010s output. The 96.90% RTP places it among the higher-RTP slots on this list, with low-to-medium volatility that delivers frequent payouts without significant balance drain.
The Linked Reels feature is the standout mechanic. Reels are randomly linked together at the start of each spin, with two to four adjacent reels showing identical symbols. This significantly increases the hit frequency on any spin where reels are linked, and it’s the main reason Dazzle Me’s session math feels gentler than the 76 ways-to-win figure would suggest. The free spins round triggers from three or more scatter symbols and awards 8-16 spins with a 2x multiplier on all wins, scaling up payouts during the bonus without altering the base low-vol profile.
5. Blood Suckers
- Provider: NetEnt
- Release Date: 2009
- RTP: 98%
- Volatility: Low
- Paylines: 25
- Max Win: 1,014x
- Best Feature: Free Spins with 3x Multiplier + Vampire Slaying Bonus
Blood Suckers holds the position of NetEnt’s highest-RTP video slot at 98%, which is two full percentage points above the industry average of 96%. The vampire-horror theme is built around dark gothic imagery, vampire portraits, garlic, holy water, silver stakes, and crucifixes set across a 5-reel, 25-payline layout. The graphics show their 2009 release date, but the underlying maths has kept this title relevant for 15+ years.
Two bonus features layer on top of the base game. The free spins round is triggered by landing three or more vampire bride scatter symbols and awards 10 free spins with all wins tripled. The free spins round is where most of the title’s session payouts originate, and the 3x multiplier is what pushes the maximum win up to 1,014x your stake. The Vampire Slaying Bonus is a pick-and-click round triggered by three or more bonus symbols on a payline, where players choose coffins to reveal cash prizes by slaying vampires.
The combination of 98% RTP and low volatility produces a hit rate of approximately 41% across long sessions. That sustained payout frequency is what makes Blood Suckers genuinely useful for clearing wagering requirements: balances erode slowly enough that most 100-spin sessions stay close to neutral, with frequent small-to-medium wins keeping the wagering counter active.
6. 1429 Uncharted Seas
- Provider: Thunderkick
- Release Date: 2014
- RTP: 98.6%
- Volatility: Low
- Paylines: 25
- Best Feature: Expanding Wild + Free Spins
1429 Uncharted Seas is one of the highest-RTP slots in the entire online casino industry at 98.6%, paired with a low-volatility math model that makes it a strong wagering candidate. Thunderkick’s 15th-century maritime exploration theme runs across hand-drawn sea monsters, mermaids, ships, and cartographic illustrations, set against an aged-parchment backdrop. The art direction is unusually distinctive for a slot, drawing on illuminated medieval manuscripts rather than the standard polished CGI.
The 5-reel, 25-payline layout uses two main features. The expanding wild is the headline mechanic: when a wild symbol lands on reel 3, it expands to cover the full reel and triggers a re-spin with the wild locked in place, which doubles win lines passing through the centre column on every re-spin. The free spins round triggers from three or more scatter symbols and awards 10 free spins with the same expanding wild mechanic active throughout the bonus. The maximum win is comparatively low for the modern slot market, but the genuinely outstanding RTP and gentle volatility profile make this one of the best slots on the market for working through wagering requirements without significant balance erosion.
7. Esqueleto Explosivo
- Provider: Thunderkick
- Release Date: 2014
- RTP: 96%
- Volatility: Low
- Paylines: 17
- Best Feature: Mucho Multiplier Cascading Reels
Esqueleto Explosivo is Thunderkick’s Day of the Dead-themed cascade slot, built around a Mexican folk-music aesthetic where cartoon mariachi skull symbols sing along to a cumbia soundtrack. The 5-reel, 17-payline layout uses a cascading reels mechanic where every winning combination removes the matched symbols and replaces them with new ones from above, allowing chain wins to develop within a single paid spin. The 96% RTP sits at the industry average, but the cascading reels mechanic significantly improves effective hit frequency.
The Mucho Multiplier is the defining feature. Each cascade win on a single spin increases the multiplier applied to subsequent cascade wins, scaling 2x, 4x, 8x, and 16x as more cascades chain together. The Explosivo Wild appears periodically and triggers an explosion that destroys all surrounding adjacent symbols, creating new cascade opportunities. The low-volatility profile means cascade chains arrive frequently throughout sessions, making this title one of the gentlest options on the page for sustained wagering progression.
8. Devil’s Delight
- Provider: NetEnt
- Release Date: 2010
- RTP: 97.6%
- Volatility: Low
- Paylines: 20
- Best Feature: Soul Reaper Bonus + Sin Spins Free Spins
Devil’s Delight runs at a 97.6% RTP, placing it second only to Blood Suckers among NetEnt’s high-RTP catalogue. The hellish theme is rendered with NetEnt’s typical dark-comic art direction, with cartoon devils, sinful symbols, and underworld iconography running across a 5-reel, 20-payline layout. Despite its 2010 release, the title’s combination of high RTP and low volatility has kept it widely available across UK and EU regulated operators.
The two bonus features deliver the title’s payout depth. The Soul Reaper Bonus is triggered by landing three or more grim reaper bonus symbols across a payline, opening a pick-style round where players collect souls and assign them to one of seven sins. Each sin pays a different cash multiplier, and the round continues until the player collects three souls of the same sin, which triggers the Sin Spins free games round. Sin Spins awards 10 free spins where wins are multiplied based on which sin governed the trigger.
The combined RTP and bonus frequency make Devil’s Delight one of the cleanest wagering picks in the NetEnt catalogue. The low-volatility profile keeps balance erosion gentle during the base game, while the layered bonus structure provides genuine upside potential without inflating the variance.
9. Jackpot 6000
- Provider: NetEnt
- Release Date: 2002 (HTML5 update 2014)
- RTP: 98.86% (at maximum bet, optimal Supermeter strategy)
- Volatility: Low
- Layout: 3 reels, 5 paylines
- Best Feature: Supermeter Mode + Fixed 6,000 Coin Top Prize
Jackpot 6000 is one of NetEnt’s earliest classic slots and remains one of the highest-RTP titles in the entire industry when played at maximum bet using the optimal Supermeter strategy. The traditional 3-reel, 5-line fruit machine layout features classic symbols including cherries, BARs, sevens, joker hats, and the namesake “6000” symbol that pays the fixed top prize. There is no progressive jackpot. The 6,000 coin top prize is fixed and paid out when five identical 6000 symbols land across the central payline at maximum bet.
The Supermeter mode is the title’s defining feature. After any winning spin in the base game, players can choose to bank the win or transfer it to the Supermeter reels at the top of the screen. Supermeter mode plays across the upper reels with a fixed bet level, and joker symbols award mystery prizes between 100 and 2,000 coins depending on position and bet size. The 98.86% RTP figure applies specifically to gameplay using max bet and following the optimal Supermeter collection strategy. The base game RTP is significantly lower, so the headline figure requires deliberate play, but for players willing to play through the Supermeter mechanics correctly, this is one of the highest theoretical-return slots available.
The classic 3-reel layout and absence of complex feature mechanics make Jackpot 6000 a divisive choice among modern slot players. There are no free spins, no cascading reels, no bonus rounds. But the combination of an industry-leading RTP at correct play and genuinely low volatility keeps the title functional as a wagering tool, especially for players who appreciate traditional fruit-machine pacing.

One closing note worth flagging: some operators specifically exclude the highest-RTP slots on this page (most commonly Blood Suckers and Jackpot 6000) from bonus wagering contributions because of their generous return rates. Always check the bonus terms and excluded games list before starting your wagering session, particularly if you’re playing at an operator new to you.
