SlotRanker Score: 68 — 40 Extra Crown Coin Boost by Amusnet
https://slotranker.com/amusnet-interactive/40-extra-crown-coin-boost#scoreSlot Summary
How It Plays
Base-game combinations use 40 paylines across a 5x4 grid. The crown wild can expand on the middle reels, while scatter symbols pay without needing an ordinary line combination.
The crown's substitutions exclude the Dollar and Star scatters. A separate randomly triggered Jackpot Cards game adds a picking event, distinct from collecting and improving coins inside Coin Boost.
Bonus & Free Spins
Coin Boost begins with 5 free spins and retains the coins that triggered it. Upgrade symbols move existing coins from Bronze through Silver and Gold to Diamond, while Plus Spins symbols add spins before becoming Bronze coins.
An upgrade landing on a maximum-level coin redirects to an adjacent coin. If every existing coin has reached its highest level, an available empty position can receive a new Bronze coin instead.
This game is searched most in Brazil, Germany, and Finland.
True Cost to Play
Expected average based on this slot's 96.2% RTP — individual sessions vary with volatility.
Estimate only, for entertainment purposes — treat gambling as entertainment, not a way to make money, and set a budget you can afford to lose.

Questions & Answers
40 Extra Crown Coin Boost FAQ
No. Coin Boost can activate when at least one coin appears in the base game; a coin's appearance does not guarantee activation.
Filling the entire grid during the feature applies a x2 multiplier to the winnings from that feature.
The Coin Boost feature includes fixed Mini, Minor, Major and Grand jackpot levels, represented by jackpot coins.
