40 Lucky Wilds Hot Coin Boost Slot Review
A brass-capped glass tube glows blue and crackles with lightning beside a heap of spilled gold, set against a soft backdrop of oversized four-leaf clovers in layered greens. In Amusnet‘s 40 Lucky Wilds Hot Coin Boost, that hoard isn’t decoration – it’s the honest summary of the whole design. The fruit machine around it barely pays for itself, and every real win in this game is a coin that landed on screen and waited for the feature to open.
It runs on a 5×4 grid with 40 fixed paylines, familiar fruit symbols doing the paying, and a four-level jackpot folded into the coin feature. It’s a similar build to Trophy Rush Triple Boost, another Amusnet title that stacks a collection mechanic onto a traditional frame, though the coin ladder here is the more elaborate of the two.
Base Game & Features
This is a straight line game. Forty fixed paylines across five reels and four rows, wins paid left to right, and only the highest combination on each line counts. The reels are stocked with sevens, melons, grapes, bells and the citrus-and-cherry tier below them, alongside the coins and jackpot symbols that drive everything else.
Amusnet publishes no RTP figure for this one, and no volatility rating either. The paytable, at least, is fully laid out:
- 7 – pays 0.25x for two, 1.25x for three, 6.25x for four, 25x for five
- Watermelon / Grapes – pays 1x for three, 2.5x for four, 10x for five
- Bell – pays 0.5x for three, 1x for four, 3.75x for five
- Plum & Lemon / Orange & Cherry – pays 0.25x for three, 0.5x for four, 2.5x for five
Those are modest line pays. The sevens top out at 25x for a full line, and the fruit tier bottoms out at a quarter of your stake, so the reel wins here are pocket money. The money in this game is in the coins, and the base game’s main job is putting them on screen.
Every base-game round also runs the Mystery Trigger quietly in the background. Some coins can be positioned from the Pot during any spin, and when that happens the Coin Boost Feature is guaranteed to fire. It can’t rescue a coinless screen: no coins, no feature.
One structural detail matters before the feature breakdown: the Static Jackpot and Jackpot Cards systems swap depending on where you are. The Static Jackpot levels are live in the base game, and once Coin Boost begins they take over completely, replacing Jackpot Cards for the duration of the round. Both roads lead through the coins.
40 Lucky Wilds Hot Coin Boost Bonus Features & Free Spins
Coin Boost Feature
Land at least one Coin in the base game and there’s a chance the feature triggers. When it does, it opens with every Coin that started it already in place, plus five free spins. From there the reels carry only Coins, Jackpot symbols and Special symbols, so every spin is collection rather than line pays.
The round ends when the screen fills or the spins run out, and every coin value is paid at the end, not as it lands. A full screen applies a x2 multiplier to the total win on top, which is the feature’s ceiling moment: a packed grid of maxed coins, doubled.
Coin Levels
Coins come in tiers, and the ladder is where the feature gets its teeth:
- Cash Coins, level 1 – x0.5 to x3 bet
- Cash Coins, level 2 – x3 to x7 bet
- Cash Coins, level 3 – x10 to x25 bet
- Cash Coins, level 4 – x30 to x50 bet
- Mini Jackpot Coin – x10 bet
- Minor Jackpot Coin – x30 bet
- Major Jackpot Coin – x100 bet
- Grand Jackpot Coin – x1000 bet
Special Spins Coin
During the feature a Special Spins Coin can land, awarding two, three or five extra spins before it transforms into a Bronze Coin. Several of them can land in one round, so a feature that starts with five spins can run considerably longer.
The upgrade rules are straightforward. An upgrade animation lifts an existing coin to the next level; if that coin is already maxed, a random adjacent coin gets the upgrade instead. If every coin is maxed and there’s a free position, a random position fills with a Bronze Coin. A fully maxed, fully stocked screen awards nothing extra. Filling the screen is what pays double.
The Jackpots
Two jackpot systems run here. The Static Jackpot carries four fixed levels, Grand at 1000x, Major at 100x, Minor at 30x and Mini at 10x, and a level is won when its symbol lands during the bonus game. Static levels can pay out more than once in the same feature, which is a genuinely generous rule.
Outside the feature, Jackpot Cards is a randomly triggered round available in the base game. Two systems, one reel set, and the coins are the thread through both.
Buy Bonus
There’s a buy menu, and it’s priced in plain multiples of the total bet:
- Premiums – Coin Boost with Gold, Platinum, Mini, Minor, Major and Grand coins only, for 100x the total bet
- High Coins – Coin Boost with Silver, Gold, Platinum and Jackpot coins except Mini, for 100x the total bet
- Jackpots Only – guarantees at least 1 Jackpot Coin with Mini, Minor, Major and Grand coins; price 250x the total bet
The two 100x options differ in what they exclude rather than what they cost. Premiums strips out the Silver tier entirely, while High Coins keeps it and drops the Mini jackpot instead. The 250x Jackpots Only buy is the outlier: at two and a half times the price of the others, its entire premium buys the guaranteed Jackpot Coin, which starts at the Mini’s 10x and only climbs from there.
Our Honest Verdict
Overall Rating: 7.1/10
Most of a session here is spent watching fruit pay pennies while you wait for the coins to matter, and honestly, that waiting is the point. You choose this game for one reason: when the Coin Boost round opens, the grid becomes a coin ladder climbing in front of you, and the pot of gold in the artwork finally starts earning its place.
The ladder is the strength. Coins upgrade mid-round, spins coins stretch the feature past its five-spin start, and a jackpot level can pay twice in one bonus, so a good round genuinely snowballs. The weakness is everything either side of it: the line pays are small, the fruit symbols are the same fruit symbols you’ve spun a thousand times, and the flat stretches between features run long.
It’s a good fit for fruit-machine players who want a collection mechanic doing the heavy lifting under the familiar skin, and a poor one for anyone who wants the base reels to pull their own weight. If you’re happy to sit in the clover and wait for the coins, this one repays the patience.
