Meet 3 Thunder Coins: Hold and Win
3 Thunder Coins: Hold and Win is a classic fruit-machine slot from Playson, built around 5 fixed paylines and a Hold and Win Bonus Game. Land a Thunder Coin on the middle reel and the grid switches into collector mode.
Three Feature Coin types drive the round: Multi, Boost and Sticky, each changing how the Bonus Game plays out. Four jackpot tiers sit on top of the coin collection, from Mini up to the Grand Jackpot.
You can also raise your bet through the Extra Bet option for a better shot at triggering the bonus round. Any licensed 3 Thunder Coins casino running Playson titles carries this game in its slot lobby.
Theme & Visuals
The reels lean into a retro Vegas fruit-machine look. 777 Wild symbols, bells, BAR BAR stacks, mixed fruit combos with watermelon and grapes, and cherries fill the 3x3 grid in the base game.
The 3 Thunder Coins slot pairs old-school fruit-machine art with neon coin graphics that signal exactly which feature just landed.
Hold and Win Bonus Game
The Bonus Game triggers when a Thunder Coin lands strictly on the second reel. It needs any Feature Coins or regular Coins on reels one and three too. That combination locks the grid into the Hold and Win round.
The round opens with 3 respins. Every new coin that lands on the grid resets the respin counter back to 3. The round only ends once the respins run out with no new symbol landing.
Inside the Bonus Game, only coins fill the grid - Coins, Feature Coins and Thunder Coins replace the regular fruit-machine symbols entirely. Each coin carries a value of 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x or 10x the total bet, or a random Jackpot Coin value. The mix of Feature Coins that triggered the round decides which features stay active. Multi, Boost or Sticky can all carry into that Bonus Game.
Multi, Boost and Sticky Coin Features
Each coin color works through its own mechanic once the Hold and Win round starts:
- Multi (red bolt) - every red Feature Coin that lands sets multipliers of x2, x3 or x5 on three random empty cells. When no empty cells remain, new multipliers stack on top of existing ones and add together. Multi applies to a coin's value after Boost and before the coin is collected through the Thunder Feature.
- Boost (purple bolt) - every purple Feature Coin adds random boost values to three empty cells, raising coin value by +1x, +2x, +3x, +4x, +5x, +6x, +7x, +8x, or +10x of the total bet. Boosts stack on top of each other when no empty cells are left, and they apply before Multi and before collection.
- Sticky (green bolt) - every green Feature Coin places 3 Sticky Frames on empty cells, each running a random timer of 2 or 3 spins. Coins that land inside a Sticky Frame stay locked in place until the timer runs out. Sticky Frames never overlap each other.
The order matters for the payout math. Boost applies first, then Multi. The result feeds into the Thunder Feature collection at the end of the round.
Extra Feature Coin and Charge Feature
Two linked random mechanics extend the coin system. The Extra Feature Coin randomly turns into a red, purple or green Feature Coin each time it lands during the Bonus Game. It either switches on a new feature or reinforces an already active one with a matching coin.
The Charge Feature works in the base game. Any Feature Coin or Thunder Coin that lands gives a chance to trigger Charge Feature. It adds enough Coins, Feature Coins and Thunder Coins to the grid to launch the Bonus Game immediately with its matching feature active.
Bonus Rounds
Two systems close out the bonus cycle on top of the Bonus Game and the three coin features above. The Thunder Feature collects coin values, and a four-tier jackpot ladder sits behind it.
Thunder Feature
Thunder Feature triggers when a Thunder Coin lands together with any Coin, in either the base game or the Bonus Game. It collects the values of every coin on the grid, including Feature Coins and Jackpot Coins. The total adds to the current spin win in the base game, or to the Total Win inside the Bonus Game.
Inside the Bonus Game, Thunder Feature is also what closes out the round. Once the respins end, every coin value still on the grid passes into the Total Win through this same collection step.
Jackpot Coins
Jackpot Coins land at random during a Thunder Feature trigger, and the specific coin that appears decides which jackpot tier pays out.
| Jackpot | Multiplier |
|---|---|
| GRAND | 1000x |
| MAJOR | 100x |
| MINOR | 30x |
| MINI | 15x |
All four Jackpot Coins can only appear through the Thunder Feature. The Grand Jackpot at 1000x is the rarest of the four and overrides any regular coin value it lands on.
Payout Table
Payouts run on the 5 fixed paylines using the classic fruit-machine symbols. The Wild (777) substitutes for every symbol except the coins. Coins, Feature Coins and the Thunder Coin pay nothing directly. They only convert into cash through the Thunder Feature or a full Bonus Game round.
| Symbol | 3x payout (at $1 stake) |
|---|---|
 |
$50.00 |
 |
$20.00 |
 |
$10.00 |
 |
$8.00 |
 |
$4.00 |

$1.00 |
The Thunder Coin lands only on the second reel. Feature Coins in red, purple or green, along with the regular Coin, land only on reels one and three. There, they trigger the Bonus Game instead of paying a line win.
Extra Bet Feature
Turning on Extra Bet applies a x1.5 multiplier to your base stake and doubles the chance of triggering the Bonus Game. The trade-off is direct: a higher cost per spin in exchange for statistically more frequent entries into the Hold and Win round.
RTP, Volatility & Max Win
3 Thunder Coins: Hold and Win runs at 95.43% RTP, calculated from a simulation of 10 billion rounds. Volatility is Medium-High. It blends frequent small coin collections through the Thunder Feature with occasional large wins. Those big wins land when a Bonus Game runs long with Multi and Boost both active.
The Bonus Game caps at 10,000x the bet. If a round's total win reaches that ceiling, the respins continue to their natural end. The payout still locks at 10,000x regardless of further coin values. The volatility profile favors smaller bets and longer sessions while you wait for a Bonus Game trigger.

Why Hold and Win Slots Still Draw Players
Most Hold and Win clones run on a single bonus coin type that does one job. 3 Thunder Coins: Hold and Win splits that job across three separate Feature Coins. Each one changes the grid in a different way instead of stacking identical multipliers.
The Charge Feature adds a second way into the bonus round entirely. Typical Hold and Win slots require the standard trigger combination every time. This 3 Thunder Coins Hold and Win release skips that requirement. The base game can shortcut straight into a Bonus Game with a feature already active, which keeps the path to the round less predictable.

FAQ
A Thunder Coin has to land on the second reel together with any Feature Coins or regular Coins on reels one and three. That combination locks the grid into the Hold and Win round with 3 starting respins.
Multi (red) sets stacking multipliers on empty cells. Boost (purple) adds flat value boosts to coins. Sticky (green) locks coins in place with a Sticky Frame timer for 2 or 3 spins. Each color changes the grid differently instead of repeating the same effect.
Boost applies first, raising the coin's base value. Multi applies second, multiplying that boosted value. The Thunder Feature then collects the final result into the Total Win.
Yes. Charge Feature can fire in the base game whenever a Feature Coin or Thunder Coin lands. It adds enough coins to the grid to launch the Bonus Game directly. It skips the usual Thunder Coin on reel two requirement.
The respins still play out to their natural end. The final payout locks at 10,000x the bet regardless of any additional coin values collected after the cap is reached.
Extra Bet applies a x1.5 multiplier to your stake and doubles the odds of triggering the Bonus Game. It costs more per spin, so it suits players prioritizing bonus frequency over stretching a fixed bankroll.
