Bill & Coin 2: Mummy Mischief Slot Review
Relax Gaming’s sequel to the Bill & Coin series arrives with an Egyptian mummy theme that balances the familiar coin-collection mechanics players loved in the original with significant expansions to the bonus feature set. Released in September 2025, Bill & Coin 2: Mummy Mischief brings cascading reels, expandable symbols, and three distinct bonus modes into a tightly designed 6×4 grid. For those seeking a feel-good, light-hearted diversion with strategic choice in bonus selection, this sequel delivers a polished and well-rounded slot experience that retains the series’ identity while introducing fresh gameplay depth.

Base Game & Features
Bill & Coin 2 operates on a 6-reel, 4-row grid with 4,096 ways to win using cascading mechanics rather than traditional paylines. The game supports bet ranges from 0.10 to 60 per spin, accommodating both cautious players and high-stake enthusiasts. The mathematical foundation sits at 96.10% RTP with medium-high volatility, producing approximately one winning combination every five spins (hit frequency of 21.71%). This balance ensures regular engagement without constant large wins, creating good rhythm for the volatility level.
Cascading Reels & Coin Collection
The central mechanic revolves around collecting coins and cascading symbols. When winning combinations form, symbols drop away and new symbols cascade down to fill the gaps. This continuation creates chain reactions where multiple wins stack from a single spin. Coins collected during these cascades contribute to progression towards bonus feature triggers, adding a collection element that keeps players engaged during base gameplay.
Bone Wilds & Dice Modifiers
Bone Wild symbols land randomly during the base game and trigger the Dice Modifier feature. When activated, a die rolls to determine a multiplier boost from x1 to x6, which applies to your Global Multiplier meter. This mechanic adds meaningful variance to base spins, nudging players toward higher multiplier levels that amplify the impact of subsequent feature triggers.
Upgrade Spins
During base gameplay, players can encounter Upgrade Spins—special spins where coin values escalate, increasing the potential payout of any winning combination that lands. This welcome addition provides occasional explosive moments within base play, rewarding patients without requiring feature activation.
Bonus Features & Free Spins
Bill & Coin 2 distinguishes itself through three independent bonus modes, each selectable during free spins, alongside a powerful Super Bonus option that runs all three simultaneously. Triggering is straightforward: 3 scatter symbols award 8 free spins and present the player with a choice of bonus mode. This strategic decision—picking which mode suits your playstyle—ensures every feature activation feels meaningful rather than predetermined.

Three Bonus Modes
Sticky Coins Mode holds all coins collected during free spins in place, ensuring nothing is lost whilst cascading continues. This mode emphasises the collection mechanic and rewards consistent win patterns during the feature.
Multiplier Ladder Mode operates a progressive system where each cascade during free spins increases a global multiplier. Starting at 1x, it climbs with every cascade event, potentially reaching substantial values by spin’s end. Players chasing larger multipliers gravitate towards this option for its escalating potential.
Book Bonus Mode expands symbols on the reels, creating larger blocks that fill more positions and generate bigger payouts. Expanding symbols transform the visual landscape and create dramatic multi-reel coverage opportunities, appealing to players seeking dramatic visual wins.
Bonus Buy & Super Bonus
Players can purchase free spins directly through the bonus buy feature. The Standard Bonus costs 100x your bet and triggers one of the three bonus modes as described above. For those seeking maximum volatility, the Super Bonus costs 500x your bet—a eye-watering price tag—but activates all three bonus modes simultaneously with 8 free spins. During Super Bonus rounds, Sticky Coins hold, the Multiplier Ladder climbs, and symbols expand concurrently, creating intense stacked win potential. This premium option caters specifically to high-volatility chasers willing to pay handsomely for explosive potential.
It’s worth noting the bonus buy pricing reflects Relax Gaming’s confidence in feature volatility; the 500x cost isn’t arbitrary but rather calibrated to the exceptional max win potential (15,000x stake) when conditions align perfectly during Super Bonus rounds with stacked multipliers and expanding symbols working in tandem.

Our Honest Verdict
Bill & Coin 2: Mummy Mischief successfully positions itself as a refined sequel that adopts the classic cascading and coin-collection features whilst introducing fresh bonus mechanics. Relax Gaming has executed the sequel formula effectively, respecting the original’s DNA whilst expanding the feature toolkit meaningfully.
The standout strength lies in the three-mode bonus system and strategic selection during free spins. Unlike many sequels that lock players into predetermined feature mechanics, the choice between Sticky Coins, Multiplier Ladder, and Book Bonus ensures every feature activation reflects player preference. The 96.10% RTP with medium-high volatility positions this firmly in the fair-but-exciting tier, appealing to players seeking balanced risk-reward dynamics. The 21.71% hit frequency prevents extended dry spells from becoming frustrating, whilst the 15,000x maximum win potential—genuinely achievable through Super Bonus combinations—satisfies those chasing substantial multipliers.
The Egyptian theme, whilst cheerfully presented, represents perhaps the game’s weakest element. Mummy-themed slots have saturated the market, and the visual approach here, though polished, doesn’t reinvent the wheel thematically. Some players will note that individual bonus rounds sit on par with—or occasionally pale slightly compared to—the original Bill & Coin’s features, though the expanded feature breadth compensates.
Bill & Coin 2 will genuinely appeal to series fans and players seeking strategic bonus selection, medium-high volatility gameplay, and a well-rounded mechanics package. The Multiplier Ladder and Super Bonus rounds bring clever depth to gameplay, making every spin feel purposeful. Mobile optimisation is solid across iOS and Android, maintaining crisp visuals and smooth performance on phones, tablets, and desktops. This is exactly the sequel fans of the original wanted and deserved—polished, feature-rich, and respectfully evolutionary rather than revolutionary.
