What is Udder Carnage: Holy Cow?

Udder Carnage: Holy Cow is built around Prize Coins that can land on reels 2 to 5. These Coins carry values from 0.5× to 5× the total bet and can be collected when a Collector appears on reel 1 or 6.

Beef Force and Astro Moo Coins can also land anywhere on the grid. These special Coins are automatically linked to the corresponding character above the reels and can randomly trigger their own Hold & Win feature.

Beef Force uses a regular Hold & Win game with 3 respins and one of three possible Cow modes. Astro Moo is the stronger version, using 4 respins, a larger 5x6 grid and enhanced versions of the Cow abilities.

Prize Coins

Prize Coin symbols can only appear on reels 2, 3, 4 and 5.

Each Prize Coin carries a value between 0.5× and 5× the total bet. If a Collector symbol appears during the same spin, the visible Prize Coin values are collected and paid immediately.

These Coins also play an important role in both Hold & Win features, where different Cow abilities can collect, multiply or replace them with special prizes.

Collector symbols

Collector symbols can only appear on the outer reels: reel 1 and reel 6.

If one or more Prize Coins are visible during the same spin, the Collector gathers the values from all Prize Coins on reels 2 to 5.

This makes the two outer reels act as collection points for the Coin values that land in the middle of the grid.

Wild symbols

Wild symbols can appear on reels 2 to 5 and substitute for regular paying symbols.

The Wild does not replace:

• Prize Coins
• Cow Coins
• Collector symbols
• Bonus symbols

This keeps the main feature-triggering symbols separate from the Wild mechanic.

Beef Force and Astro Moo Coins

Beef Force and Astro Moo Coins can land on all 6 reels.

When one of these Coins appears, it is automatically collected by the matching character above the grid. This can randomly trigger the corresponding Hold & Win feature.

The Beef Force Coin can lead to the regular Beef Force Hold & Win.

The Astro Moo Coin can trigger the stronger Astro Moo Super Hold & Win.

The collection animation by the characters is part of the visual presentation of the game. Each spin remains independent and game outcomes are determined separately.

Beef Force Hold & Win

A Beef Force Cow Coin can trigger the Beef Force Hold & Win.

The feature begins with 3 respins. Each time a new symbol lands, the respin counter resets back to 3.

The bonus continues until:

• no respins remain; or
• the grid is completely filled.

When the feature ends, the values of all symbols on the grid are added together and paid as the total bonus win.

During Beef Force Hold & Win, one of three different modes is used:

• Boost Mode
• Collect Mode
• Multi Mode

Boost Mode

During Boost Mode, the Red Cow can transform symbols into Special Prize symbols.

Possible Special Prizes, from highest to lowest, are:

• Grand Special: 5,000×
• Mega Special: 500×
• Major Special: 50×
• Minor Special: 20×
• Mini Special: 10×

This allows Boost Mode to replace regular positions during the bonus with fixed Prize symbols carrying much higher values.

Collect Mode

During Beef Collect Mode, the Yellow Cow can land on any reel.

When it appears, it collects values from randomly selected Prize Coins that landed during the same spin.

Unlike the regular Collector, which gathers all visible Prize Coins on reels 2 to 5, this Cow ability works with a selection of Coin values during the Hold & Win feature.

Multi Mode

During Beef Multi Mode, each Blue Cow that lands can apply a multiplier to random Prize Coins on the grid.

The available multiplier ranges from:

• 2×
• up to 5×

After applying the multiplier, the Blue Cow also awards a random direct value of up to 5× the total bet.

Multi Mode therefore combines increasing existing Prize Coin values with an additional instant prize.

Astro Moo Super Hold & Win

The Astro Moo Coin can trigger the stronger Astro Moo Super Hold & Win feature.

This bonus starts with 4 respins instead of 3. Whenever a new symbol lands, the respin counter resets back to 4.

The grid also expands. The feature is played on a 5x6 layout, creating more available positions than in the regular Beef Force Hold & Win.

All three Cow abilities can become available during Astro Moo:

• Red Cow
• Yellow Cow
• Blue Cow

Each ability is stronger here than in the regular Hold & Win feature.

Red Cow in Astro Moo

During Astro Moo Super Hold & Win, the Red Cow can transform symbols into a Special Grand Prize symbol.

The Grand Special is worth 5,000× the total bet.

This makes the Red Cow directly connected to the highest fixed Special Prize available in the game.

Yellow Cow in Astro Moo

The Yellow Cow uses a stronger collection mechanic during Astro Moo Super Hold & Win.

Instead of collecting values from only selected Prize Coins, the Yellow Cow collects values from across the entire grid.

This means a single Yellow Cow can gather a much broader set of Prize Coin values during the feature.

Blue Cow in Astro Moo

The Blue Cow is also significantly stronger during the Super Hold & Win feature.

In the regular Multi Mode, the maximum multiplier is 5×. During Astro Moo, the Blue Cow can apply multipliers of up to 50×.

These multipliers can be applied to Prize Coins already present on the grid, allowing existing Coin values to increase considerably.

Filling the 5x6 grid

If all 30 positions of the 5x6 grid are filled during Astro Moo Super Hold & Win, a prize of 5,000× the total bet is awarded.

The feature also ends when no respins remain.

At the end of the bonus, the values of all symbols on the grid are added together and paid as the total feature win.

Free Spins

Free Spins are triggered by landing 3, 4, 5 or 6 Bonus symbols during the base game.

The number of awarded spins depends on the number of Bonus symbols:

• 3 Bonus symbols: 5 Free Spins
• 4 Bonus symbols: 8 Free Spins
• 5 Bonus symbols: 12 Free Spins
• 6 Bonus symbols: 15 Free Spins

During Free Spins, either Beef Force Hold & Win or Astro Moo Super Hold & Win is guaranteed to trigger.

This makes the Free Spins more than a separate bonus round, as they also provide a direct route into one of the two main Hold & Win features.

Special Prize symbols

Different fixed Special Prize symbols can appear during the Hold & Win features.

The prize values, from highest to lowest, are:

• Grand Special: 5,000× the total bet
• Mega Special: 500× the total bet
• Major Special: 50× the total bet
• Minor Special: 20× the total bet
• Mini Special: 10× the total bet

These fixed prize levels play an important role in Boost Mode and in the stronger Astro Moo Super Hold & Win feature.

Why Udder Carnage: Holy Cow stands out

Udder Carnage: Holy Cow stands out by offering two Hold & Win features that play quite differently from one another.

Beef Force begins with 3 respins and uses one of three possible modes. The feature can focus on transforming symbols, collecting Coin values or applying multipliers to Prize Coins.

Astro Moo takes the concept further. The grid becomes larger, the feature begins with 4 respins and all three Cow abilities can become available. The Yellow Cow can collect values from the entire grid, while the Blue Cow can apply multipliers of up to 50×.

The Free Spins connect both bonus paths by guaranteeing that either Beef Force or Astro Moo will trigger during the feature.
