Thunder Cash Dollar King is a wonderfully simple and highly playable slot from online slots developer Ainsworth. Remember “ThunderCats,” that wildly famous ’80s cartoon starring space felines from the planet Thundera? 

Well, Thunder Cash Dollar King, though not officially licensed, is like a nostalgic trip down memory lane, sporting the same iconic colors and lettering as the classic ThunderCats logo. This sly nod to the cherished cartoon takes you back to your childhood, transforming your regular slot experience into a colorful blast from the past but with a dark undertone of lightning and thunder.

Game Overview

Thunder Cash Dollar King features 5×3 reels and up to 20 paylines. Its symbols are vibrant and beautifully designed with a touch of the ThunderCats nostalgia mentioned above but primarily focused on a lightning storm. 

The primary gameplay of Thunder Cash Dollar King follows the typical slot setup, requiring players to amass symbol combinations on active paylines.

Thunder Cash Dollar King is a medium volatility game with a return to player (RTP) of -2567. Minimum bets are $1 up to a maximum of $200. 

How to Play

Playing Thunder Cash Dollar King, like most online slots, is straightforward. First, select your stake level and hit spin. The aim is to line up matching symbols across the paylines. Unique symbols like the Dollar King or Thunder Cash icons trigger special features, increasing your chances of securing a hefty slots bonus.
To get a clear view of the game’s paytable and to learn more about the value of each symbol, click on the gear icon next to the Thunder Cash logo at the lower left corner of the screen. This action opens up a panel for adjusting your bet and the active lines. The panel also contains an “I” symbol; clicking on it pulls up additional information with two tabs: “How to Play” and “Rules.” To view the paytable, click on “Rules.”

The game also has an autoplay feature. To access it, click on the plus sign at the top left corner of the spin button. This will open up a panel that allows you to automate up to 25 spins according to your chosen parameters.

Once you’ve set your preferences, confirm them by clicking the green check mark at the bottom of the panel. The number of spins you’ve selected will display in the spin button’s center. 


Thunder Cash Dollar King is among the classic online casino games in the true sense of the word. Its straightforward symbols and minimalist aesthetic cut straight to the chase, letting you get straight into the action without any fuss. Despite its ThunderCats-inspired logo, Thunder Cash Dollar King is essentially a traditional slot. 

The backdrop is the Dollar King Bonus Wheel, with lightning bolts streaking behind as the wheel turns. There isn’t much of a musical soundtrack, but rather the sound of rain gently falling, interspersed with cracks of lightning and thunder as the reels spin.


The game’s symbols are fairly simple and include traditional playing cards along with gold coins, diamonds, gold bars, a dollar king multiplier, a thunderbolt wild and dice symbols. 


When triggered, the Dollar King feature locks in place for the rest of the spin, multiplying winning opportunities when a corresponding Dollar King symbol lands on the last reel with a designated multiple up to 5x your winnings. 

There’s also the Thunder Cash free spin feature which adds up to 8 free spins when triggered by three Thunder Cash symbols. Free spins can be retriggered from within the Thunder Cash feature and have the potential to deliver huge winnings. 

Bonuses and Jackpots

Should you trigger the Dollar King feature, you also open up the bonus wheel, which spins with multiple values available. When the wheel stops, you win the multiple of that specific value up to a maximum of 5x the value. 

One of the most appealing aspects of Thunder Cash Dollar King is a slot bonus in the form of four progressive jackpots — Mini, Minor, Major and Grand. The jackpots can be triggered anytime during play when 5 wilds are displayed. The Grand Progressive Jackpot can reach into the millions depending on when it was last won.

Wizard’s Wand Money Up

When you launch Ainsworth’s Wizard’s Wand Money Up, you’ll immediately notice its unique design that mirrors land-based cabinet slots. This slot features bonus prize ladders on top of the 5×3 grid, each reel boasting its own ladder. The control panel is conveniently positioned at the bottom right, while the Mini, Minor, Major and Grand Jackpots information is displayed top right, beneath the game logo. 

This layout accentuates the game’s emphasis on bonuses and jackpots, making it a top choice for players looking to win some real money. The reels host low-value royal cards from 10 to ace alongside high-value, magical-themed symbols, including a potion, a scroll, an owl and a wizard. The game’s wild symbol is a spooky cauldron, complemented by multiple scatter symbols — a grimoire and 1x, 2x and 3x multipliers.

Moon Dancer

Many casino slots draw inspiration from Eastern cultures, yet Moon Dancer distinguishes itself through its high-quality gaming experience. Also developed by Ainsworth, creators of other successful titles like Golden Ox: Golden Cash, King of the Jungle and Action Dragons, Moon Dancer is a sophisticated 5-reel, 50 payline slot with a -1801 RTP. 

This game is considered high volatility, meaning wins may not be frequent but are typically substantial when they do happen. While other jackpot slots may offer larger potential rewards, they often fall short in gameplay quality compared to Moon Dancer.
