Royal style meets coin-collecting action in 100 Extra Crown Coin Boost, Amusnet’s newest addition to the Coin Boost series. Combining an all-time favourite regal visual identity with evolving coin values and an array of engaging features, the game brings an extra layer of anticipation to every spin.
The gameplay is centred around the Coin Boost feature, which can be triggered at any moment and awards five Free Spins on a dynamic 5x4 grid. During the feature, coins can climb through four levels – Bronze, Silver, Gold, and Diamond – with each upgrade adding to the excitement as players follow their progress.
Adding an unexpected twist, the Mystery Trigger can drop coins onto the reels and instantly activate the Coin Boost feature. This keeps the action unpredictable, while the coin-upgrade mechanic gives the bonus round a clear sense of progression.
Players who prefer to get straight to action can take advantage of the Buy Bonus feature to access the game’s special features without waiting for the Coin Boost to trigger naturally.
With its upgraded coin mechanics, surprise feature activation, and jackpot potential, 100 Extra Crown Coin Boost brings a fresh take to the classic slot format.
Coin Boost
The feature can be triggered when at least one coin appears on the screen during the base game. It starts with all Coin symbols that have already triggered it and five initial Free Spins.
When the Upgrade lands on an already existing coin, it upgrades it to the next-level coin. If the Upgrade lands on a maximum-level coin, a random adjacent coin will be upgraded instead of it. If all coins on the screen are at the maximum level and there are still free positions, a random position will be filled with a coin at the lowest level (Bronze). If all coins on the screen are at the maximum level and there are no free positions, no further upgrades will take place.
Special Coins and Multipliers
All Jackpot Coins (Mini, Minor, Major, Grand) can land during the base game and the Coin Boost Feature. Also, a special Plus Spins can land on the screen during the Coin Boost Feature. It first awards additional spins and then transforms to a first-level cash coin (a bronze coin). Multiple Plus Spins Coins can also land during the feature. In case the whole grid is filled during the feature, all winnings are multiplied by x2!
Expanding Wild
The Crown Wild symbol appears on the second, third, and fourth reel and substitutes for all symbols on the same reel except for the Dollar and the Star Scatter symbols.
Buy Bonus
The feature enables the player to buy the Coin Boost feature, which guarantees that at least one coin will land and trigger the feature.
Gamble
Play the game and multiply your winnings through the Gambling feature!
Jackpot Cards
The Jackpot Cards bonus game is triggered at random during the gameplay to allow players to win impressive jackpots.
