Bill & Coin 2: Mummy Mischief Game Review (New Slot Demo)
Introduction to Bill & Coin 2: Mummy Mischief
This new game from Relax Gaming landed in September 2025, and I've been testing Bill & Coin 2: Mummy Mischief nearly daily since. As someone who played the original Bill & Coin series quite a lot, I was excited to see how Relax Gaming would evolve the formula. This time, our cash-collecting duo has traded their usual antics for an Egyptian adventure, complete with pyramids, mummies, and ancient curses. The game maintains that quirky humor the series is known for while adding some serious firepower with a 15,000x max win potential.

Gameplay and Special Features of Bill & Coin 2: Mummy Mischief
Bill & Coin 2 runs on a 6×4 grid with 4,096 ways to win, and offers plenty of action. The base game mechanics are straightforward – you're looking to land matching symbols from left to right across the ways. The real excitement starts when you hit the bonus features though.
The game revolves around three core bonus mechanics that you can choose between when you trigger the Bonus Pick with 3 scatter symbols. The Sticky Coins feature makes coin symbols stick on the grid and nudge down one row with each spin, accumulating cash values over multiple spins. The Multiplier Ladder increases your win multiplier on every spin and every win, with dice symbols providing additional boosts that can push it beyond x500. The Book Bonus works like classic expanding symbol games, choosing one symbol to expand across reels and paying over 10 fixed lines.
What makes this system brilliant is the player choice element – you get to pick which feature suits your mood or strategy for that particular bonus round.
Free Spins and Bonus Features
The bonus system is where Bill & Coin 2 really shines. Landing 3 scatters gives you 8 free spins and the choice between the three bonus types I mentioned. But the real prize is the Super Bonus, triggered by landing 3 scatters including 1 Super Scatter. This activates ALL three bonus features simultaneously – sticky coins drop and nudge, the multiplier ladder climbs, and expanding book symbols appear.
During any bonus round, collecting 5 spin symbols adds +5 spins and another expanding symbol (up to 3 total), which can really extend the feature and boost your winning potential. I've had some incredible runs where the multiplier ladder combined with multiple expanding symbols created chains of massive wins.
The Super Bonus is definitely where the 15,000x potential lies. When all three features work together, the winning combinations can become absolutely insane, especially if you get lucky with the multiplier ladder climbing high while sticky coins accumulate substantial values.

My Thoughts About This Demo Game™
After some serius testing, I can say the game is quite fun to play and comes with many features. The Super Bonus is of course the most interesting bonus, but cost is also 500x your bet so crazy expensive. I recommend only buying the bonus if you're playing at a casino that offers the 96.10% payout. I tried also playing it with the 94% RTP version, and bought around 20 super bonuses and only one win was slightly above my cost, and ALL rest was under what it cost, and ended up in a big lose.
This experience really highlights how important RTP is when you're buying expensive bonuses. The 500x cost for Super Bonus is steep, and you need every percentage point of RTP working in your favor to make it worthwhile long-term.
The variety in bonus options keeps things interesting though. Some times I prefer the steady accumulation of Sticky Coins, other times I chase the multiplier ladder for those explosive wins. The Book Bonus can be hit-or-miss depending on which symbol gets chosen to expand, but when you get a premium symbol expanding across multiple reels, the payouts can be big.
What impressed me most is how well the three features complement each other in the Super Bonus. Watching sticky coins accumulate while the multiplier ladder climbs and book symbols expand creates genuine excitement. The animations and sound effects really enhance the experience – you can feel the tension building as multiple features work together.
The high volatility definitely shows though. You can go long stretches without hitting bonuses, and even when you do, the regular Bonus Pick doesn't always deliver big wins. The player choice element helps since you can adapt your strategy based on how the bonus starts, but ultimately you're still at the mercy of the RNG.
The Egyptian theme is well executed without being too serious about itself. Bill and Coin's personalities shine through in the animations, and the mummy mischief concept works well. It's not groundbreaking thematically, but it's charming and fits the game's personality.
Bill & Coin 2: Mummy Mischief successfully builds on the original formula with meaningful improvements. The Super Bonus concept is really good, and in the normal bonus the player choice adds strategy, and the 15,000x potential is genuinely achievable.
Just be very careful with those expensive bonus buys and make sure you're playing on the highest RTP version available.
Overall Rating: 8.9/10 – A feature-rich sequel that delivers on its promises, but requires careful bankroll management due to high volatility and expensive bonus options. Will i play again? yes but only on the high RTP version which can be found here.
