How To Play Thunder Cash Dollar King
The Dollar King variant of the Thunder Cash slot games is a fairly simple money machine, played on a 5×3 reel grid with 20 fixed paylines. Spin and betting options are neatly laid out on a control bar below the reels, with game rules and paytable info accessible from the “info” button.
As the paylines are fixed, you must select your bet per line from the coin control next to the total bet display. Total bets range from $1 to $200 per spin. Once you’ve set your bets, hit the “Spin” button to play spin by spin or lock in your bet for up to 50 autospins.
Thunder Cash Dollar King Game Features
Thunder Cash Dollar King runs a medium-volatility math model with a generous 96.25% return to player (RTP), which means you should, as a rule, see more consistent wins throughout your session. The game features wild symbols with their standard role of substituting symbols to create winning combinations on a payline, but they also carry cash prizes of up to 50x your bet.
Scatters come in two forms linked to either the Thunder Cash or Dollar King mechanics. The Dollar King scatter only lands on reels 1 and 5, while the Thunder Cash slot symbol can land on any reel and offers up to 100x in scatter pays. You also get multiplier modifiers with either 2x, 3x, 4x, or 5x options. These only land on reel 5.
Thunder Cash Dollar King Bonuses and Jackpots
The two scatters are the keys to the bonus features of this game. The Thunder Cash round is unlocked by landing three or more Thunder Cash scatters anywhere on the reels. This awards eight free spins to start, while five more free spins can be added each time you land three more scatters. During this round, wilds will lock in place when landing to help you create winning combinations.
Landing a Dollar King scatter on reels 1 and 5 will trigger the bonus wheel with multiple cash prize segments and a bonus segment. This feature can also be triggered with one scatter on reel 1 and a multiplier on reel 5. The multiplier will then be applied to any wins from the wheel. If you land the bonus segment on the wheel, you’ll be taken to a new wheel that you can spin to win one of the game’s four jackpot prizes.
How To Win Thunder Cash Dollar King
One thing that makes this game so special is how easy they’ve made the win mechanics — even from the base game. Even as few as two matches on a payline can trigger a win for higher-paying symbols. But of course, your big-time wins will be easiest to achieve from the bonus rounds.
Thunder Cash Dollar King Graphics and Design
The game’s aesthetic could be loosely inspired by an old animated TV show from the 80s. It’s got all the chrome and lightning you’d expect from shows like Thundercats or He-Man. Although none of these characters feature in the game, the polished aesthetic and stormy sound effects are a subtle nod to an era that made precious metals a staple sci-fi feature in TV shows and gaming titles.
Thunder Cash Dollar King Symbols
The game features a range of blinged-out versions of popular slot symbols, from lightning bolts to gold bars and lucky 7s. It’s important to note that there are separate paytables for the base game and the free spins round. Here’s a look at both of them:
