How to Play the Wild Joker Stacks Slot Machine

Typical of traditional slot games, there’s a collection of classic symbols on the reels, all with a pretty realistic look that helps to bring the Wild Joker Stacks slot to life on PCs, Android, Windows, and iOS devices. Cherries, lemons, watermelons, and golden bells are among them, along with single, double, and triple BAR symbols. A gold and purple ‘7’ is the most valuable of them all, while the grinning Joker, in her bright red hat, has the power to act as others, and a diamond unlocks the main bonus round.

Easy to understand control buttons run up one side of the reels. You click the pile of coins tab, then choose a wager level from 0.25 to 30.00 per spin from the 10 options available. The arrows in a circle button above this will activate an automatic spins mode, and the ‘I’ further up the controls unlocks the Wild Joker Stacks slot payout table.
