Monster Money Slot Review

About the Game

Welcome to Monster Money, a video slot by Reflex Gaming featuring 20 paylines, free spins, a “Max Play” mode, a double-or-nothing gamble feature, and more.

Monster Money is a 5-reel, 3-row video slot with 20 paylines. The game includes 9 standard paying symbols, which award a win when three or more matching symbols – or two or more “Monster Hunter” or “Gravestone” symbols – land along a payline, starting from the leftmost reel. Additionally, there are various “Money Monster” symbols that pay out as line wins regardless of the specific combination. The game also features a bonus symbol that can appear anywhere on the screen; landing 3 or more of these symbols triggers the free spins bonus round.

Buy Bonus

By clicking the “Buy Bonus” button, the player is presented with two options to purchase entry into either standard or “super” free spins, at a cost that is a specific multiple of the chosen base bet.
Standard free spins cost 100x the selected bet amount. Super free spins cost 200x the selected bet amount and are guaranteed to trigger the “Bat Bonus” modifier, which provides free spins with additional bonus enhancements.
A spin purchased via the “Buy Bonus” feature is guaranteed to land 3-5 Scatter symbols on the reels, awarding the corresponding number of free spins.
There is a maximum bet limit for purchasing a bonus. This maximum limit may vary from the information provided above, depending on the platform where you are playing.

Double Gamble Feature

A gamble option may be offered for all wins in the base game, including “Cash Monster” wins during “Max Play” mode. This feature is controlled via a gamble button, which can be set to OFF, ON, or 5X OR MORE. If set to ON, the gamble option is offered for any base game win that does not also trigger the free spins bonus. If set to 5X OR MORE, the option is offered for any base game win equal to or greater than 5x the base bet.

The gamble feature offers two options. On the left Gamble Wheel, the current prize can be multiplied by 1.5x, 2x, 3x, 5x, or 10x (with resulting cash values ​​rounded up to the nearest payable amount). On the right Gamble Wheel, the current prize can be wagered for a chance to win 5, 10, 15, 20, or 25 free spins. The wagered value can be adjusted using the plus (+) and minus (-) buttons on either side, and the probability of winning the gamble is displayed on the Gamble Wheel itself.

Once a gamble option is selected, both pointers begin to spin. If a pointer stops on a green segment of the chosen wheel, the gamble is won, and the current prize is updated to the new, wagered value. If a pointer stops on a red segment, the gamble is lost, and the round ends with no prize awarded. The gamble feature continues until the current prize is collected, the gamble is lost, or the maximum prize on the cash Gamble Wheel is reached. The Gamble Wheel for free spins is disabled once the value exceeds the cost of the highest-tier free spin entry.

Odds of winning a gamble feature for free spins:

5 free spins -> 10 free spins = 50.00%
5 free spins -> 15 free spins = 33.33%
5 free spins -> 20 free spins = 25.74%
5 free spins -> 25 free spins = 21.47%
10 free spins -> 15 free spins = 66.67%
10 free spins -> 20 free spins = 51.47%
10 free spins -> 25 free spins = 42.94%
15 free spins -> 20 free spins = 77.21%
15 free spins -> 25 free spins = 64.42%
20 free spins -> 25 free spins = 83.44%

Golden Bet

A player can increase their bet by 1.5x to activate the “Bonus Respin” feature, which boosts the chances of triggering free spins. This feature is awarded when 2 bonus symbols land on the reels; the reels that did not land a bonus symbol spin again, providing a second chance to trigger the bonus. The Golden Bet can be activated in both standard mode and “Max Play” mode. Any line wins or “Cash Monster” prizes are paid out for both the initial spin and each subsequent respin. The paytable and the values ​​of the monster prizes do not increase when the Golden Bet is enabled.

Max Win

The overall theoretical return to player (RTP) is 94.00%.
The maximum win is 5,000x the base bet. If the free spins feature in Monster Money exceeds 5,000x the base bet, a payout of 5,000x is awarded, and the feature ends.

Game Rules

Money Monster Symbols

There are 6 different Money Monster symbols in the game, each displaying a corresponding cash value.

The cash value of any monster is awarded whenever a Monster Hunter symbol appears anywhere on the reels; if multiple Monster Hunters land, each one awards the total sum of all monster values ​​present on the reels.

The Monster Hunter symbol appears on the reels only during Free Spins and “Max Play” mode; in the standard base game, these cash values ​​are displayed in a dimmed state.

The cash values ​​are multiples of the selected base bet, with the value of the monster prizes increasing according to their hierarchy (see below). When the Golden Bet feature is active, the cash prizes do not increase.
Monsters can display the following values ​​(as multiples of the base bet):

Hand – 1x, 2x, 3x, 4x.
Mummy – 5x, 6x.
Werewolf – 8x, 10x.
Frankenstein – 15x, 20x.
Dracula – 25x, 35x, 50x.
Golden Dracula – 100x, 200x, 500x, 5000x.

Wild Symbol

The Wild symbol is the Monster Hunter symbol; it substitutes for all symbols except the Bonus symbol. During the Free Spins bonus, the Monster Hunter symbol may display a multiplier, which applies only to the cash monster prizes.

The Monster Hunter can display the following multipliers: 1x (no multiplier displayed), 2x, 3x, 5x, and 10x.

“Bat Bonus” Modifier

For every bonus symbol that lands, a bat flies into the castle above the reels. If, by the end of a spin, one or more bats have entered the castle, a bolt of lightning may strike – either triggering the “Bat Bonus” modifier or changing the background state. The background state persists across all bet modes but is tracked separately for each bet level.

If the “Bat Bonus” modifier is triggered, a flock of bats flies out from the castle, with some of them striking reels that do not yet contain a bonus symbol. Each struck position is transformed into an additional bonus symbol. At least one extra bonus symbol is added, guaranteeing the activation of the Super Free Spins bonus. Following this, the background state is reset.

Free Spins

Landing 3 or more bonus symbols in the base game triggers free spins.

At the start of the free spins, the two lowest-value monster types on the reels are upgraded to the next monster tier. The number of free spins awarded depends on the number of bonus symbols that triggered the feature:

3 bonus symbols award 10 free spins.
4 bonus symbols award 15 free spins.
5 bonus symbols award 20 free spins.

If triggered via the “Bat Bonus” modifier, you receive “Super Free Spins,” which are enhanced by one or more upgrades granted upon entry. These may include pre-advancing the progress trail, upgrading the lowest-value monster symbol that can appear, or setting a minimum multiplier value for any “Monster Hunter” symbols that land.

During free spins, a “Monster Hunter” symbol may appear on the reels, collecting all cash-monster prizes currently visible anywhere on the reels. This symbol may also carry a multiplier, which is applied to the total value of all collected monsters. A 9-stage progress trail is displayed above the reels; each time a “Monster Hunter” symbol lands, it is added to this trail.

For every 3 “Monster Hunter” symbols added to the trail, the next level is unlocked. Once the current set of free spins is exhausted, this level awards 10 additional free spins and upgrades all remaining lowest-value monster symbols on the reels to the next, higher tier – as indicated at each stage along the progress trail. Any Hunter symbols that land on the reels without any Money Monster symbols present are locked in place and remain on the reels until either a Money Monster symbol appears or the free spins conclude. Free spins are played using the same bet amount and number of lines as the base game in which they were triggered.

“Max Play” Mode

The “Max Play” button allows you to play an alternative version of the main game at the same bet level. In this mode, the Monster Hunter symbol is added to the reels, triggering cash monster prizes, while only monsters, Hunters, and bonus symbols remain on the reels. All other standard paying symbols are removed from the reels and replaced by a small pumpkin symbol, which has no prize value.
