Theme and atmosphere
Pyramids and the Sphinx sit under a cartoon sun, bright and chipper rather than dusty and reverent, and the percussive, adventure-forward soundtrack pushes in the same direction. Closer to holiday snaps with the lads than a tomb crawl. The new dice character is a genuinely charming addition, which matters when the setting itself is one of the most worked-over in slots.
How does the Bill & Coin 2: Mummy Mischief Slot Demo play?
Bill & Coin 2: Mummy Mischief plays across 6 reels and 4 rows with 4,096 ways to win. RTP is 96.1% in the game’s top configuration, volatility is medium-high, and the maximum win is 15,000x your bet. Bets run from €0.10 to €60 per spin, and Relax Gaming released the game on 2 September 2025.
Wins clear and new symbols drop in from above, so one spin can chain into several hits. The Win Multiplier starts inactive every spin and climbs with each set of cascade wins, which is the engine the whole base game runs on. Coin symbols pay their x-bet value when they reach the bottom row, and if the multiplier is live at that moment, the Coin payout rides it. Bone Wilds substitute like a normal wild and can also fire a Dice Roll worth +1 to +6 on the multiplier.
Six of a kind pays around 1x for the card ranks and 2x to 10x for the fruit and premium symbols, so the base game is setup work punctuated by multiplier spikes and Coin payoffs rather than a steady drip.
Bonus features
Three scatters award 8 free spins plus your pick of one of three modes, and the three play very differently.
Sticky Coins locks landed Coins in place and nudges them down a row each spin until they hit the bottom and pay, with an active multiplier boosting the payout. Watching value accumulate on screen is the appeal, and it is the calmest of the three.
Multiplier Ladder makes the Win Multiplier sticky for the whole round and grows it on every regular win, including on spins that pay nothing. Bone Wild dice rolls can shove it past x500, and if tumbles keep landing late in the round it turns explosive.
Book Bonus picks a random pay symbol and turns it into an expanding symbol that fills reels and pays across 10 fixed lines over any 3 or more reels. Collect 5 spins symbols and you get another expanding symbol, up to three.
Collecting 5 spins symbols in any bonus, Super Bonus included, adds +5 free spins.
⚠️ Worth Knowing: During Book Bonus expanding symbol wins, the game stops evaluating 4,096 ways and pays on 10 fixed lines instead. The coverage of a full expanding symbol and the 3+ reel rule go some way to offsetting that, but it is a real trade-off and it is not signposted before you pick.
Land three scatters with one of them a Super Scatter and all three modes run simultaneously across 8 free spins. That is the Super Bonus, and it is where the game stops being a pleasant diversion: sticky Coins collecting under a permanently rising multiplier while expanding symbols fill reels is the only realistic route to 15,000x. Paid routes exist where permitted: 100x buys the standard pick, 500x buys the Super Bonus outright, Bonus Reels costs 10x a spin and shows only scatters, super scatters and blanks, Coin Row costs 25x and guarantees a full row of Coins, and Upgrade Spins costs 5x a spin, guarantees a Bone Wild and turns any bonus you trigger into a Super Bonus.

What are the best casinos for Bill & Coin 2: Mummy Mischief?
Any site that carries the studio’s library will have this one, so the sorting factor is what surrounds it: whether the buy features are switched on in your market, and what the withdrawal terms look like. Our list of Relax Gaming casinos is the place to start.
Free spins packages pair well with a game whose ceiling only opens up inside a bonus round, but the wagering attached decides whether that is actually useful. Compare the current offers on our casino bonuses hub before depositing anywhere.
Play the Bill & Coin 2: Mummy Mischief Slot Demo for free
The demo above is the full game, buy menu included where your region allows it, with play-money credits. Use it to answer the question the game asks you: 100 to 200 spins is enough for a casual look, 200 to 400 if you want a fair read on how often bonuses arrive, and you can find more titles in our demo slots library while you are here.
💡 Tip: Trigger the bonus three times in the demo and take a different mode each time. Sticky Coins, Multiplier Ladder and Book Bonus feel nothing alike, and knowing which one you actually enjoy is worth more than any strategy advice.

Pros and cons
| ✅ Pros | ❌ Cons |
|---|
| Three genuinely different bonus modes to pick from | Each mode is modest on its own |
| Super Bonus runs all three at once | Book Bonus drops to a 10-line evaluation |
| 15,000x ceiling on medium-high maths | Heavily worked-over Egyptian setting |
| Bright cartoon presentation and the dice character | Base game needs cascades before anything happens |
Verdict
- The Super Bonus is the destination, and everything else is the queue for it
- Multiplier Ladder is the mode most likely to produce a session you remember
- 500x for the Super Bonus directly is steep, but 5x per spin on Upgrade Spins is the cheaper way to guarantee the same round
- Cheerful enough to sit through the quiet stretches, which not every medium-high game manages
Best for: players who like choosing their own bonus format and want a ceiling above the usual 10,000x.
Skip if: you want a base game that carries itself between features.
Set your limits before you leave the demo behind, and stop when it stops being fun.
In summary
