Paris Gamblers review · Amusnet · 2026
40 Extra Crown Coin Boost builds a classic crown-and-fruit layout around a five-spin coin feature rather than relying on the theme alone. Amusnet publishes a 96.02% RTP, 5x4 grid, and 40 fixed paylines, but it does not publish a volatility label, transferable currency stake range, or maximum-win figure on the public product pages.
Paris Gamblers score
4.0/5
Best for
players who like fixed paylines, evolving cash coins, and static jackpots
A coherent coin-upgrade slot with clearly published RTP and layout facts, held back by three important mathematical details that still need checking in the active game information.
40 Extra Crown Coin Boost is a 5x4, 40-line Amusnet slot where five Coin Boost spins upgrade cash coins through bronze, silver, gold, and diamond levels.
These are the numbers and mechanics to compare before opening a nearby review.

The feature shape and volatility tell you more about the session feel than the theme alone.
Compare volatilityThe base game uses five reels, four rows, and 40 fixed paylines. The Crown Wild appears on reels 2, 3, and 4 and expands across its reel, substituting for ordinary symbols but not the cash-coin or Star Scatter symbols. The scatter pays anywhere, while Mini, Minor, Major, and Grand are fixed jackpot tiers rather than one progressive prize.
Coin Boost begins with five spins and the coins that triggered it already on the board. Upgrades move a coin through bronze, silver, gold, and diamond levels; an upgrade landing on a diamond can upgrade an adjacent coin instead. Plus Spins add rounds before becoming bronze coins, and a completely filled grid doubles the feature win. Amusnet also lists Mystery Trigger, Buy Bonus, Gamble, and Jackpot Cards routes, but the active game information controls availability, stakes, volatility, and the win ceiling for the deployed version.
This suits players who want a fixed-line slot with one central collection loop. The provider-stated 96.02% RTP, 40-line layout, five-spin start, upgrade ladder, and full-grid 2x rule make the visible feature structure easy to compare.
Skip it if a provider-published volatility class, stake range, or maximum win is essential before opening a game. Those fields cannot be inferred from the crown theme, the jackpot labels, or the number of feature routes, so confirm them in the live information screen.
The 5x4 base grid fits a phone cleanly, but upgraded coin levels, Plus Spins, jackpot coins, and the expanding wild can make Coin Boost visually dense. Use the active information panel to confirm local stakes and the unpublished volatility and maximum-win details.

RTP mechanics guide
RTP is the theoretical long-run share returned as prizes by one game configuration. It does not predict a session, win frequency, or payout size.
Free-spins mechanics guide
Free spins are extra rounds awarded by an in-game feature. The paytable sets the trigger, starting spin count, retrigger rules, and any wild or multiplier changes.
