There are 40 fixed paylines, 4 rows, and 5 reels on the Happy Hooves slot machine. All symbols start on the leftmost reel and pay out from left to right. Per line, only the largest win is rewarded.
The A-J royals are the lowest paying symbols on the reels. These are matched in hue (blue, purple, green, and red) with horses that pay more. The most lucrative symbol is the red horse, which pays 1, 2.5, or 3.75 times your stake when you land three, four, or five in a row.
The game features four Wilds that have the same colour scheme as the regular symbols. They all serve as stand-ins for identically coloured symbols. Only reels 1, 3, and 5 include the Scatter, which is a golden horse and horseshoe. If you get three or more of those, the PowerNudge Respin function will start.
All reels may have the Mystery symbol, which when it lands will activate the PowerNudge function. Every one of them will open to reveal something hidden behind.
In the event that a Golden symbol falls, all mystery symbol locations respin, revealing either a Scatter symbol or a random money value given as a multiplier of the total bet. Following the payment of all cash values, if there are three or more Scatters, the bonus feature will begin.
All reels containing Mystery symbols will nudge down one position to reveal a different symbol from above, and the other reels will respin while the Mystery symbols are there.
In the Happy Hooves slot machine, land three or more scatters to activate the PowerNudge Respin feature. First, an automatic spin is initiated, during which a minimum of eight Mystery symbols will land and be divided between two randomly selected reels. Similar to the base game, the game will nudge and respin.
In this bonus round, the Nudge Up sign is a new symbol that can be unveiled by the mystery symbols. The nudge will go up rather than down if this lands. In the event that more than one Nudge Up symbol appears, the nudge will advance the reels by the same amount of positions.
