High-Voltage Mechanics
Hold and Win — The Core Loop
Land a qualifying set of Clover symbols on the 5×3 grid to trigger Hold and Win. All clovers lock in place and you receive 3 respins. Every new clover that lands resets the respin counter. The round continues until no new clovers appear or the grid is full.
Each Clover carries its own coin value. At the end of the round, all locked clover values are summed. Fill the entire grid and you trigger the Grand Jackpot (3,000x) on top.

Super Bonus — Grid Expands to 5×5
The Super Clover symbol is a special trigger. When it appears during the base game, the grid expands from 5×3 to 5×5 — adding 10 extra positions. This means 25 total cells to fill with clovers instead of 15.
The expanded grid doesn't just give you more space — it unlocks the Super Jackpot (10,000x) which is ONLY available during the 5×5 bonus. Fill all 25 positions and the Super Jackpot is yours on top of all coin values. That's where the 15,000x theoretical max lives.

Feature Clovers — Multi, Collect, Mystery
During the Bonus Game, special Feature Clovers can appear alongside regular clovers. Three types, each with a different effect:
Multi
Carries a multiplier that applies to all collected clover values at the end of the round. Multiple Multi clovers combine for an even bigger boost.
Collect
Gathers the coin values of all clovers currently on the grid and awards that combined total on the spot.
Mystery
Conceals its effect until it lands, then reveals a random modifier — you don't know what you're getting until it resolves.

HARVEST NOW →What 96.08% RTP Actually Means
These are the published figures from Playson, not a claim that we sat through a test session. Here is how the 96.08% return and high volatility play out over the long run.
The Published Numbers
- RTP
- 96.08%
- Volatility
- High
- Max win
- 15,000x
- Layout

A Worked Example
- Bet size
- $0.10
- Over 10,000 spins you stake
- $1,000.00
- Theoretical return at 96.08%
- ~$960.80
- Long-run expected cost
- ~$39.20
Read the RTP as a long-run average, not a session
That ~$39.20 cost is the theoretical average across tens of thousands of spins — it says nothing about a single session. On a high-volatility slot the reality is streaky: long dry spells, then most of the value arriving in a burst when the bonus round hits. The 15,000x ceiling and the published 96.08% both live at the extremes of that variance, so treat any short run as noise around the average.

Mathematical model only. Real sessions deviate due to volatility and finite spin counts. Hit-target probability uses an illustrative power-law approximation — actual hit rates depend on paytable structure, bonus triggers, and operator-side variance. Not financial advice.

Bonus Types at Partner Casinos
Here is the sort of promo you tend to run into at casinos that carry 4 Supercharged Clovers. Caps, wagering and which games count all shift from one operator to the next, so give the T&C inside each lobby a proper read before you opt in.
First Deposit Bonus
Your opening deposit usually gets doubled up to a set ceiling, and the extra balance is handy for feeding the 0.20 minimum spin while you chase the Hold and Win respins. Plenty of partners bolt on a Free Spins bundle you can point straight at this Playson reel.
Free Spins Package
Sometimes a handful of spins land the moment you register, sometimes they trickle in across your first few top-ups. Either way, they let you test-drive the Super Clover trigger without denting your own bankroll first. Just remember the winnings carry wagering.
Reload Bonus
Once the welcome deal is spent, reloads keep your topping-up rewarded. The match rate sits lower than day one, but a mid-week reload is a tidy way to bankroll a longer run at that 15,000x ceiling.
Cashback
High volatility means dry patches happen, and cashback softens them by handing back a slice of net losses. We rate the wagering-free versions highest, since the refund lands as real cash you can spin again straight away.
Wagering Bonus
That bonus balance is not withdrawable until you clear a rollover target. Do the maths before opting in, because the lower the multiplier, the sooner any Grand or Super Jackpot hit actually becomes yours to cash out.
VIP / Loyalty Levels
Regular spinners rack up points that convert into level jumps, a personal host and quicker withdrawals. Climb high enough and the perks start to look properly worthwhile if this reel becomes part of your rotation.
Slot Tournament
Leaderboard races on Playson titles pop up often and 4 Supercharged Clovers lands in the featured pool more than most. With a 15,000x top payout on the table, one supercharged Bonus Game can rocket you up the standings in a single spin.
Birthday / Loyalty Reward
A little something on your registered birthday: bonus credit, a spin bundle or wagering-free cash. Nothing life-changing, but a free crack at the Feature Clovers never goes amiss.
Every deal here rides on the operator's own rules. You need to be 18+ (21+ in a few places) and sign off on the casino's wagering and withdrawal terms before a single penny of bonus lands in your account.
