Udder Carnage: Holy Cow Game Details

Udder Carnage Holy Cow Base Gameplay

Prize Coins Meet Collectors on the Outer Reels

Prize Coin symbols can land on reels 2–5 with values from 0.5× to 5× the total bet. Collector symbols are restricted to reels 1 and 6.

Whenever Prize Coins and a Collector land on the same spin, the Collector awards the visible Prize Coin values from the four middle reels. Gaming Corps highlights this Prize Coin Collection mechanic as one of the game's core features.

Beef Force Opens Three Hold & Win Modes

Beef Force Cow Coins can randomly trigger the standard Beef Force Hold & Win Game. The feature begins with three respins, and every new symbol resets the counter to three.

Three cow abilities can become active:

• Boost Mode: Red Cow symbols can transform into Mini, Minor, Major, Mega or Grand Special Prize symbols.
• Collect Mode: Yellow Cows collect values from random Prize Coins appearing on the same spin.
• Multi Mode: Blue Cows apply 2×–5× multipliers to random Prize Coins, then award an additional random value of up to 5× the bet.

The bonus ends when the respins are exhausted or the grid becomes full.

Astro Moo Expands the Grid and Cow Powers

An Astro Moo Cow Coin can instead trigger the Astro Moo Super Hold & Win Game, which starts with four respins and expands the grid to five symbols high.

This upgraded feature allows all three Cow symbols to land, but their powers are stronger. Yellow Cow collects Prize Coin values from the entire grid, while Blue Cow multipliers can reach 50×. Red Cow can transform into a Grand Special Prize.

Completely filling the 6×5 grid awards 5,000× the total bet. Gaming Corps specifically highlights the expanded grid and multipliers up to 50× in its official feature description.

Free Spins Guarantee a Cow Feature Trigger

Landing Bonus symbols awards Free Spins according to the number appearing:

• 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 or Astro Moo is guaranteed to trigger. Gaming Corps confirms that up to 15 Free Spins can be awarded with additional opportunities to activate the Hold & Win features.

Hot Bet and Coin Hunt Change Feature Access

The game also includes two optional wager features.

Hot Bet costs 2× the current bet and, according to the in-game rules, gives three times the chance to trigger Free Spins. Its maximum RTP is listed as 93.92%.

Coin Hunt costs 5× the current bet and places a Collector symbol on every spin, strengthening the Prize Coin collection mechanic. Its maximum RTP is 94.03%.

Two Hold & Win Routes Power the Farmyard Battle

Udder Carnage: Holy Cow builds most of its bonus depth around the contrast between Beef Force and Astro Moo. The standard Hold & Win offers three specialised cow modes, while the Super version increases the grid, strengthens the Collect and Multiplier powers and introduces a 5,000× full-grid prize.

Gaming Corps has scheduled Udder Carnage: Holy Cow for September 10, 2026, with 4,096 ways to win, volatility rated 9/10 and a maximum win of 10,000× the bet.
