Super Twins

Super Twins from Backseat Gaming in partnership with Hacksaw Gaming is a mouse-themed slot released in October 2024, starring two brothers called Twitch and Tails who look suspiciously like the rodent answer to Mario and Luigi. The 5-reel, 4-row layout runs on just 14 paylines with bets from 0.10 to 100, high volatility rated 5 out of 5, an RTP of 96.32 percent, and a 12,500x max win.

Let me be upfront: the base game is dry. There is no modifier, no random feature, nothing to break up the monotony of standard spins. With a 27 percent hit frequency, roughly three quarters of your spins return nothing or less than your stake. It is a deliberate design choice that funnels all the excitement into the bonus rounds, and whether that works for you depends entirely on your patience threshold.

The presentation, however, is genuinely lovely. The cartoon basement setting is crisp and colourful, the character design has real personality, and the audiovisual polish meets the high bar you would expect from anything bearing the Hacksaw Gaming name. It looks fantastic on mobile too. But pretty wallpaper does not fix a hollow room, and the base game needs something more.

The symbol set is classic fruit-and-royals fare. Royals from 10 through Ace sit at the bottom, paying just 1.5x to 2x for five of a kind. The fruit symbols -- oranges, cherries, grapes, and strawberries -- are worth 4x to 10x for a full line. Strawberries top the standard paytable at 10x, which is modest but functional for a high-volatility game that concentrates its real firepower in the features.

The wild symbol, designed as a mouse with the word Wild, substitutes for everything except scatters and pays 10x for five across a line. Two scatter types exist: the Mushroom scatter triggers the Floating Free Bonus, and the Star scatter triggers the Staying Stuck Bonus. The paytable itself is nothing to write home about, but it does its job as a foundation for the bonus mechanics that carry this slot.

This is where Super Twins genuinely shines. Two distinct bonus rounds give the game its identity, and both open with the Super Wheel, a dual-section spinner that determines your starting free spins (5 to 20) and a global multiplier (2x up to a tasty 100x). That wheel spin alone creates a moment of real tension -- land a high multiplier and you know the round has serious potential.

The Floating Free Bonus, triggered by three Mushroom scatters, uses roaming wilds that shift position on every spin. It is the weaker of the two in my experience, and community consensus backs that up. The unpredictability of wild placement means you can easily whiff through an entire round without much to show for it. Retriggers are possible by landing three more Mushroom scatters, which reactivates the Super Wheel and adds to your multiplier and spin count.

The Staying Stuck Bonus, triggered by three Star scatters, is the headliner. Sticky wilds lock in place for the remainder of the round, and once a few land in the right spots, every subsequent spin becomes profitable. One reviewer reported pulling nearly 2,500x from a single Staying Stuck session. The consistency of sticky wilds simply outperforms their floating counterparts, and the 200x buy cost versus 100x for Floating Free tells you even Backseat Gaming knows which round carries the bigger punch.

Five buy options are available outside the UK. BonusHunt FeatureSpins at 3x the stake makes bonus triggers five times more likely -- a sensible, affordable nudge. Super Wheel FeatureSpins at 20x gives one spin with up to 20 wilds and a 100x multiplier. Super-Duper Wheel FeatureSpins at 100x adds respins while wilds remain. Then you can skip straight to Floating Free at 100x or Staying Stuck at 200x.

The premium options are steep. Paying 200x for direct Staying Stuck access is a serious bankroll commitment, and casual players will rightly baulk. But for high-rollers chasing the 12,500x ceiling, the concentrated RTP in these rounds makes a reasonable case. The BonusHunt option at 3x is probably the smartest middle ground for most players -- affordable enough to sustain, effective enough to cut the base game grind.

The default RTP of 96.32 percent sits comfortably above the industry average, though operators can select a lower 94.24 percent option, so always check before you play. Volatility is maxed at 5 out of 5, and with a 27 percent hit frequency, this is firmly a feast-or-famine affair. The max win of 12,500x is a strong headline figure that feels genuinely attainable given how the bonus multipliers stack.

Super Twins is a game of two halves, and I mean that literally. The base game is barren -- no modifiers, no tension builders, just spinning and hoping for a scatter cluster. That is a genuine weakness, and I wish Backseat Gaming had planted something there to keep players engaged between bonus triggers.

But those bonus rounds, particularly the Staying Stuck feature, are excellent. The Super Wheel adds a layer of anticipation that most free spin triggers lack, and when a high multiplier pairs with accumulating sticky wilds, the results speak for themselves. The charming design, strong RTP, and 12,500x ceiling round out a slot that rewards patience. If you can tolerate quiet stretches for explosive bonus potential, Super Twins earns a recommendation. If you need constant base game action, look elsewhere.
