Thunder Crown
Step beyond the classic fruit machine exterior of Thunder Crown to discover a slot with electrifying potential. The game is engineered for high-energy excitement, offering a level of suspense and payout potential that is anything but traditional. This is defined by its massive 2400x max win, a powerful reward that provides a truly contemporary and thrilling twist on the familiar retro slot experience.
Thunder Crown Gameplay and Mechanics
Thunder Crown is played on a 5-reel, 5-row grid with 50 fixed paylines, where bright fruits, glowing sevens, and stars spin against a backdrop of dancing blue sparks. The game’s standout feature is its 2400x max win potential, achieved primarily through its engaging bonus rounds.
Thunder Crown’s excitement is driven by its two primary bonus features: the Free Games round and the Thunder Hold Bonus Game. The Free Games feature is triggered by landing three or more Scatters, guaranteeing a Wild symbol on every single spin to significantly enhance winning potential.
The highlight, however, is the Thunder Hold Bonus Game. This electrifying feature can be triggered randomly and transforms the entire grid for a hold-and-win style round. It is within this bonus that players have the opportunity to land one of three fixed jackpots and achieve the game’s maximum win.
Thunder Crown Theme and Visuals
Thunder Crown” is a classic fruit-themed slot with a modern, high-voltage twist. The title is prominently displayed above the reels, with a dramatic, gem-encrusted crown sitting on a thunderous, blue-and-white cloud. The soundtrack has a feel of an action thriller with occasional thunder strikes whenever you land a winning combination.
The visuals combine traditional fruit symbols like plums, oranges, and cherries with a striking background of a stormy sky, complete with flashing lightning bolts. The game’s fixed 50 paylines are clearly labelled, suggesting a straightforward and traditional gameplay experience. The vibrant colours of the fruit symbols stand out against the blue background, creating a visually appealing and energetic game.

Thunder Crown Slot Features
Endorphina has successfully merged thunder with royalty. Aside from the amazing aesthetics, Thunder Crown’s bonus features make it stand out in a crowded slot market. Will you be fired to royal rewards? Let’s take a look at the main catch.
Wild
The Crown represents the Wild symbol. Wild substitutes for all symbols, except the Scatter and Token. The Wild symbol appears on reels 2, 3, and 4 and expands vertically to complete winning combinations.
Lucky Time Feature
Token symbols appear in the base game and during Free Games, covering other symbols on the grid. When a Token appears on the grid, it releases an electric charge that strikes the Thunder Crown and then disappears. Any symbol the feature reveals can complete winning combinations. Each electric release may randomly trigger the Thunder Hold Bonus Game.
Free Games
Landing 3 or more Scatter symbols triggers Free Games with Wild symbols guaranteed to appear on the grid. Hitting 3, 4, and 5 Scatter symbols triggers 10, 15, and 20 Free Games, respectively. During the Free Games, at least one Wild symbol is guaranteed to appear on each reels’ spin. Free Games are played with the same bet as the initial triggering game and can be retriggered during the feature.
Thunder Hold Bonus Game
During the Thunder Hold Bonus Game, the main grid transforms into a new setup with 5 columns of varying heights. Landing Thunder Spheres will lock them in place, while other cells with a customised pattern continue to spin. Each Thunder Sphere reveals a cash prize multiplier, ranging from x1, x2, x3, x4, x5, x6, x7, x8, x9, x10, x15, to x30 of your total bet.
The primary objective is to fill entire columns with Thunder Spheres to win one of three fixed jackpots:
- Min Jackpot: 50x bet (awarded for filling a 4-position column)
- Mid Jackpot: 200x bet (awarded for filling a 5-position column)
- Max Jackpot: 1000x bet (awarded for filling the central 6-position column)
The feature begins with 3 attempts on a special indicator. Each spin uses one attempt, but landing new Thunder Spheres resets the count back to 3. The Bonus Game continues until all attempts are exhausted or the entire grid is filled with Thunder Spheres. Winnings from all collected multipliers and any triggered jackpots are summed and awarded at the end of the bonus.
Risk Game (Gamble)
Take a chance to significantly increase your winnings! After any win, you can choose to enter the Risk Game. Select one of four face-down cards. If your card beats the Dealer’s, your win is doubled, and you can continue (up to 10 attempts). If the Dealer’s card is higher, you lose your winnings and the round ends.
- The Joker beats all other cards and can only be drawn by the player.
- A card matching the Dealer’s is a draw; your win remains unchanged, and you can try again.
- Card probabilities are not equally distributed, and cards may reappear in subsequent rounds.
The average RTP for the Risk Game is 84%, but your odds fluctuate based on the Dealer’s card:
- Favourable Dealer Card (Low): 2 (162%), 3 (121%), 4 (113%), 5 (101%)
- Neutral Dealer Card: 6 (100%), 7 (100%), 8 (100%)
- Unfavourable Dealer Card (High): 9 (92%), 10 (78%), J (69%), Q (66%), K (64%), A (42%)
You can press TAKE WIN at any time to collect your current winnings and exit.
