Symbols and Payouts

The symbols in Mr. Bells 40 include a mix of classic fruit icons and special symbols that contribute to the gameplay mechanics. The Wild symbol is represented by Fiery Sevens, which substitute for all symbols except the Scatter (Golden Star) and the Bonus symbol (Bell). The Wild also offers payouts of 0.20x, 2x, and 5x the bet for 3, 4, and 5 symbols respectively.

The Scatter symbol is the Golden Star, which pays independently of paylines with rewards of 50x, 200x, and 1,000x the bet for 3, 4, and 5 symbols respectively. Other regular symbols include Watermelon and Grapes, which pay between 0.10x and 2x the bet, and lower-paying symbols such as Plum, Orange, Lemon, and Cherries with payouts ranging from 0.025x to 1x the bet.

Symbols often appear stacked on the reels, increasing the chances of forming winning combinations.

Gameplay Mechanics and Features

Mr. Bells 40 incorporates several gameplay mechanics that enhance the classic slot experience. The game features a Hold and Win style bonus called the Bell Bonus, triggered by landing 6 or more Bell symbols on the reels. Additionally, the Lucky Time feature can randomly trigger the Bell Bonus by collecting Bells from spins that do not activate the bonus directly, potentially adding extra Bells to start the bonus round.

During the Bell Bonus, players receive three respins with Bells held in place on the reels. Each new Bell symbol that lands resets the respin counter to three. If the entire 5x4 bonus grid is filled with Bells, the total prize is multiplied by three.

The bonus prizes include fixed jackpots categorized as Ultra Jackpot (750x the bet), Max Jackpot (75x the bet), Mid Jackpot (50x the bet), and Min Jackpot (10x the bet). Regular bonus prizes range from 1x to 50x the bet.

Another notable feature is the Risk Game, available for all payouts except when Autoplay is active. This card-based gamble allows players to double their winnings up to 10 consecutive times by beating the dealer's card. The inclusion of a Joker card provides an advantage during this gamble.

Additional technical features include Reality Check, Turbo Mode, and Autoplay, which offer players control over the pace and duration of their gaming session.

Betting Range and RTP

The betting range in Mr. Bells 40 spans from €0.40 to €100 per spin, with 27 default stake levels available. This range accommodates both cautious players and high rollers. The slot’s return to player (RTP) is set at 96.06%, which is within the average range for video slots, combined with high volatility that suggests less frequent but potentially larger wins.

The maximum win in the game is capped at 2,900 times the bet, which can translate into substantial payouts, especially during the bonus rounds.

Bonus Game and Special Features

The Bell Bonus is the central bonus game in Mr. Bells 40, offering a Hold and Win mechanic that is popular in modern slots. Triggering this bonus requires collecting Bell symbols either directly on the reels or through the Lucky Time feature. The respin mechanic during the bonus adds an additional layer of strategy and anticipation, as each new Bell symbol extends the bonus round.

The fixed jackpots add a structured prize hierarchy, with the Ultra Jackpot being the highest payout available in the bonus game. This jackpot system provides clear targets for players during the bonus rounds.

The Risk/Gamble game adds an optional extra layer of engagement, allowing players to attempt to increase their winnings through a card challenge. This feature is disabled during Autoplay to maintain game balance.
