About Holy Moo! Extreme Power

Holy Moo! Extreme Power is a 6×6 grid slot game developed by Play’n GO. Bets range from £0.10 to £5.00 per spin. The game utilises cascading mechanics with cluster pays and includes engaging features such as BOVINE FRAMES, the BOVINE MOO-MENT, COLLECTOR SYMBOLS, and a FREE SPINS round. The return to player (RTP) is shown within the game.

How to Play Holy Moo! Extreme Power

1. Select your bet using the bet buttons, or adjust with the plus and minus controls to choose your desired amount between £0.10 and £5.00.
2. Start a round by clicking the SPIN button. The spacebar can also be used to initiate a spin.
3. Once the symbols have landed, any cluster of 5 or more matching symbols touching horizontally or vertically will result in a win.
4. Winning symbols are removed from the grid and replaced by new symbols that cascade down into the empty positions.
5. The process of cascading continues until no further cluster wins are possible in that round.
6. All wins for the round—including any bonus features and scatter wins—are combined and paid out at the end of the round.

Game Rules and Winning Combinations

• The game is played on a 6-reel, 6-row grid with clusters replacing traditional paylines.
• Wins are achieved by forming clusters of at least 5 identical symbols connected horizontally or vertically, without any gaps.
• Winning clusters can start from any position on the grid.
• If multiple clusters win in a round, all winnings are added together.
• Only the highest win is paid per unique cluster.
• Bets cannot be changed during an active game round.

Wild Symbol

• The WILD symbol substitutes for any symbol except SCATTER, SUPER SCATTER, COLLECTOR, and special reward symbols triggered by BOVINE MOO-MENT (CASH SYMBOLS).
• WILD symbols can contribute to multiple winning clusters in a single spin.

BOVINE FRAMES and BOVINE MOO-MENT

• Whenever a winning cluster is formed, each position in the win is marked by a BOVINE FRAME.
• BOVINE FRAMES stay on the grid during the current spin, including all cascades.
• If a COLLECTOR SYMBOL lands while BOVINE FRAMES are present, the BOVINE MOO-MENT feature is activated. All BOVINE FRAMES transform into CASH SYMBOLS with values of 0.5x, 1x, 2x, 5x, or 10x.
• The values of CASH SYMBOLS are combined, then multiplied by the total bet to determine the win.
• MULTIPLY FORMS, if present, increase selected CASH SYMBOL values by repeating their base value for each multiplier, enhancing their worth.

Collector Symbols and the BOVINE PATH

• MOO-IGHTY ZEUS, the COLLECTOR SYMBOL, may land during a spin. Only one form can appear per spin.
• If multiple COLLECTOR SYMBOLS appear in a cascade, the total value is collected for each COLLECTOR.
• Each COLLECTOR SYMBOL in the base game progresses the BOVINE PATH. Advancing along the BOVINE PATH unlocks enhanced COLLECTOR FORMS.
• At higher levels of the BOVINE PATH, COLLECTOR SYMBOLS appear less frequently, and the probability of winning the MOO-IGHTY ZEUS instant prize adjusts accordingly to maintain consistent returns.

MOO-IGHTY ZEUS Feature and Instant Prizes

• MOO-IGHTY ZEUS is displayed beside the reels. Every COLLECTOR SYMBOL collected increases ZEUS’s power.
• When sufficiently charged, ZEUS may randomly award an instant prize: MINI (20x), MAJOR (50x), MEGA (100x), or GRAND (1000x) the total bet.
• Initially, only the MINI prize is available; other prizes are unlocked by reaching the end of the BOVINE PATH.
• This feature is not active during FREE SPINS.

Free Spins and Olympian Spins

• FREE SPINS are triggered by landing SCATTER SYMBOLS. If a SUPER SCATTER is among them, the OLYMPIAN SPINS mode is activated.
• Both FREE SPINS and OLYMPIAN SPINS grant 6 spins per trigger.
• During FREE SPINS, BOVINE FRAMES remain on the grid between spins. BOVINE FRAMES persist until a COLLECTOR SYMBOL appears, after which they are removed for the remainder of the feature.
• In OLYMPIAN SPINS, BOVINE FRAMES last for all 6 spins of the feature.
• Cascading wins continue to operate during all forms of FREE SPINS, as in the base game.
• The FREE SPINS feature cannot be retriggered during the bonus.

In-Game Controls

• Changing Your Bet: Use the bet buttons, or the plus and minus controls, to choose a new bet amount for your next spin.
• Paytable: Access and toggle the paytable display to review symbol values and feature information.
• Spin / Start / Spacebar: Initiates a game round at the currently selected bet.
• Auto Adjust Bet: If your balance is too low for your selected bet level when starting a spin, the game will reduce your bet to the highest possible amount your balance permits.

Game Integrity and Unfinished Rounds

• If your game round is interrupted, your current game information and placed bets are saved until you re-open the game, allowing you to continue from where you left off.
• Unresolved bets in unfinished games will become void after 7 days.
• Any collected items or game progress will be cleared after 180 days unless you log into any Play’n GO game during that period.
• Any game malfunction invalidates all pays and plays.
