How Does the Mr. Bells 40 Slot Base Game Work?
The Mr. Bells 40 demo operates on a 5-reel, 4-row grid with 40 fixed paylines. This 5×4 layout provides more room for symbol combinations than a standard 5×3 game. Wins are formed by matching 3 or more symbols on these lines, starting from the leftmost reel.
The paytable is straightforward, with Cherries, Lemons, Oranges, and Plums as the lower-tier symbols. Grapes and Watermelons pay more, offering 0.80 for a 5-of-a-kind hit on a 0.40 bet (a 2x win). This isn't massive, but the 40 lines combined with the stacked symbols mean these small wins can often cluster together.
What is the Role of Stacked Wilds and Scatters?
The Red 7 is the Wild symbol, a nod to Seven themed slots. It appears stacked on all reels and substitutes for all symbols except the Star and Bell. A full line of 5 Wilds pays 5x the bet. The Star is the Scatter, and its main power is that it pays from any position, ignoring paylines. Hitting 5 Scatters awards an instant 1000x bet win (a €400.00 prize on a €0.40 bet), which is a significant payout that can happen on any spin, completely outside of any bonus feature.
How to Trigger the Bell Bonus Game
The main feature is the Bell Bonus Game, which is the slot's take on the popular Hold & Spin mechanic and its link to the Bell theme. This bonus is triggered by landing 6 or more Bell symbols anywhere on the reels in a single spin. These symbols will land with either instant cash values (from 1x to 50x) or the name of a jackpot.
There's also a second-chance mechanic called the Lucky Time Feature. If you land 5 or fewer Bells—a “near miss” for the bonus—this feature can randomly activate. When it does, it will add more Bell symbols to the screen to guarantee the bonus round starts.
Inside the Bonus: How Jackpots and the 3x Multiplier Work
This feature is a classic Hold & Spin bonus. The triggering Bell symbols lock in place on a new grid, and you are given 3 attempts (spins). Any new Bell symbol that lands also locks and, crucially, resets the attempts counter back to 3. This continues until you run out of attempts or fill the entire screen.
This bonus round is where you'll find the game's four fixed Gold jackpots:
- Min Jackpot: 10x total bet
- Mid Jackpot: 50x total bet
- Max Jackpot: 75x total bet
- Ultra Jackpot: 750x total bet
These can land as special Bell symbols at any time during the feature. The biggest prize, however, comes from a full screen. If you manage to fill all 20 positions with Bells, all prize values are added together and then multiplied by a x3 multiplier. This mechanic is popular in many money-themed slots, such as the Mustang Gold slot from Pragmatic Play.
What is the Mr. Bells 40 RTP and Volatility?
The Mr. Bells 40 RTP (Return to Player) is 96.06%. This is a solid, industry-average figure. The provider doesn't officially state the volatility, but based on the paytable and feature structure, I would classify it as Medium Volatility.
The base game provides frequent, small wins from the 40 lines and stacked wilds, keeping the balance steady. The bonus game, however, holds the potential for high-payout spikes via the jackpots and the 750x Ultra Jackpot. This makes the Mr. Bells 40 game a balanced experience, sitting between a low-volatility grinder and a high-risk jackpot slot.
Is the Mr. Bells 40 Risk Game Worth Using?
The Risk Game is a “beat the dealer” card gamble feature. After any win, you can choose to risk it by picking one of four face-down cards. If your card is higher than the dealer's, your win is doubled. A Joker beats all cards, and the dealer can never get one. A tie is a push, and you can try again. You can gamble this way up to 10 times.
Here's the catch: the rules explicitly state the overall RTP for this round is 84%. This is a statistical trap. While the game shows you that your chances against a ‘2' are 162%, your chances against an ‘Ace' are a terrible 42%. Over time, using this feature will lose money faster than playing the main slot.
The Critic's Corner: The True Cost of the 84% RTP Gamble
The main argument for the gamble feature is that it lets you turn a tiny 0.20 win into something substantial. The stats are even transparent: beat a ‘2' and your RTP is 162%. The problem? You don't control when the ‘2' appears. The overall 84% RTP means that, on average, for every €100 you risk in this feature, you will get only €84 back. It's a faster way to drain your balance than the main slot's 96.06% RTP. This feature is a holdover from older classic-style slots like those from Greentube, such as Lord of the Ocean, and it's designed to prey on impatience.
The Bell's Secrets: Hidden Game Details
- Paytable Typo: Look closely at the paytable images. The text description (image 80a2e1.jpg) lists both the Max and Ultra Jackpots at 750x. This is a typo in the game's info screen. The actual values are Min 10x, Mid 50x, Max 75x, and Ultra 750x.
- Weighted Gamble: The rules state, “The probability of cards being dealt is not equally distributed.” This is a rare, transparent admission that the card draws are weighted and not from a standard 52-card deck.
- “Catch-a-Break” Mechanic: The “Lucky Time Feature” isn't just a random bonus. It's a ‘catch-a-break' mechanic, designed to step in when you just miss the bonus, turning a moment of frustration into excitement.
- Session Save: According to the rules, your unfinished games are saved for 7 days. If your connection drops during a bonus, you won't lose it.
How to Play the Mr. Bells 40 Free Play Version
Playing the Mr. Bells 40 free play version on Respinix is simple. The game loads with a demo balance (e.g., €10,000) for you to test all the features without risk.
The bet is fixed at 40 lines, so you only need to adjust your “BET” value, which is shown at the bottom (e.g., €0.40). You can use the TURBO button for faster spins or AUTO to set up autospins. Your main goal in the demo is to spin long enough to trigger the Bell Bonus Game at least once to see the Hold & Spin mechanic in action.
Vlad's Expert Take
Honestly, my main tip for the Mr. Bells 40 demo is to ignore the Gamble feature. I know, I know, it's tempting. But that 84% RTP is a bankroll killer. All the game's real potential is packed into the Bell Bonus Game. Focus your time on understanding the rhythm of the base game and seeing how long it takes to trigger that bonus. The gamble is just a distraction.
What Slots Are Similar to Mr. Bells 40?
Mr. Bells 40 blends Classic fruit imagery with a modern Hold & Spin jackpot feature.

The ‘What If?' Scenario: A Stacked Wild Twist
So I was playing the demo, and I thought… what if the Stacked 7 Wilds did more? Right now, they're just substitutes. What if landing a full stack of Wilds on a reel also dropped a single Bell symbol? It wouldn't guarantee the bonus, but it would make those full-stack-wild moments feel… more impactful. It would tie the base game's main feature (the stacked wilds) directly to the bonus game's trigger (the bells). It might make the bonus trigger a bit more often, sure, but it would make the base game far more exciting. Just a thought.
Final Verdict on the Mr. Bells 40 Slot
So, what's the final word on the Mr. Bells 40 slot? It’s a solid, no-nonsense game. It does exactly what it says on the tin. It's not flashy, it's not going to change the industry. But it’s… reliable.
