Bonus Games in 3 Thunder Coins
The bonus game triggers when a Thunder Coin lands on reel 2 during the base game. It must land together with any Feature Coins or regular Coins on reels 1 and 3.
Once active, only coins appear on the grid: regular Coins, Feature Coins and Thunder Coins. Each carries a value of 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x or 10x of total bet, or a random jackpot value.
The round starts with 3 respins. Every new coin that lands on the grid resets the respin counter back to 3. When respins run out, all Thunder Coin values on the grid are added to the total win.
The bonus game total is capped at 10,000x bet. If that cap is reached before respins end, the round still plays out, but the payout locks at 10,000x.
Feature Coins: MULTI, BOOST and STICKY
MULTI (red lightning) drops multipliers of x2, x3 and x5 onto three empty cells. If no empty cells remain, the multipliers can land on existing multipliers and their values add together. MULTI applies to a coin's value after BOOST and before the Thunder Feature collects it.
BOOST (purple lightning) drops random bonus values - +1x to +10x of total bet - onto three empty cells, raising a coin's value. If no empty cells remain, the bonuses can stack on existing bonus values. BOOST applies before MULTI and before the Thunder Feature collection.
STICKY (green lightning) places 3 sticky frames on empty cells, each with a random countdown of 2 or 3 spins. Coins that land inside a sticky frame stay in place until the countdown ends. Sticky frames never overlap each other.
The Extra Feature Coin is rarer. Every time it lands during the bonus game, it randomly transforms into a red, purple or green coin. This either activates a new feature coin type or adds another coin to one already active.
Thunder Feature and Charge Feature
The Thunder Feature triggers when a Thunder Coin lands alongside any other coin, in the base game or the bonus game. It collects the values of every coin on the grid, including Jackpot Coins and Feature Coins. These values get added to the current spin win in the base game, or to the total bonus win in the bonus game.
The Charge Feature gives any Feature Coin or Thunder Coin landing in the base game a chance to trigger. When it does, the grid fills with enough Coins, Feature Coins and Thunder Coins to start the bonus game, with the matching feature already active. This shortens the route into the bonus round.
Free Spins Rounds
There are no separate free spin tiers in 3 Thunder Coins: Hold and Win. Instead, the combination of Feature Coins that triggers the bonus game decides which mechanics run for the rest of the round. Every 3 Thunder Coins Hold and Win round falls into one of the levels below.
Single Feature Round
If only one Feature Coin color triggers the bonus game - red MULTI coins only, for example - only that mechanic stays active. Multipliers, BOOST bonuses or sticky frames apply on their own, depending on the color that started the round.
Multi-Feature Round
If the trigger includes Feature Coins of different colors - red and green together, for instance - both mechanics run at once. MULTI multipliers and STICKY frames each collect coins of their matching color above the reels.
Combining effects raises the chance of building high coin values. A sticky frame can hold a coin in place while a x5 multiplier later lands on it. This is three Feature Coins, one Hold and Win round at its most rewarding.
Extra Feature Activation
The Extra Feature Coin is the rarest piece on the grid. When it lands during the bonus game, it randomly transforms into a red, purple or green coin. This can activate a third mechanic in a round that started with only one or two.
A round that opened as a Single Feature Round can become a Multi-Feature Round mid-game once the Extra Feature Coin converts. The transformation happens at the moment the coin lands, with no extra trigger needed.
Symbols & Paytable
Payouts run across 5 fixed lines from left to right, with only the highest win per line counted. Coins, Feature Coins and the Thunder Coin carry no line payouts of their own. Their value comes from the Bonus Game and Thunder Feature described above. The table below shows payouts for 3 matching symbols at a $1 bet, scaled to your stake.
| Symbol | 3x Payout |

Why Hold & Win Slots Like 3 Thunder Coins Are Still Popular

Four jackpots - GRAND, MAJOR, MINOR and MINI - sit behind the Thunder Feature collection. The 10,000x cap gives the bonus game a defined ceiling rather than an open-ended target. The Charge Feature shortens the wait for that bonus game by triggering it from the base game. Extra Bet x1.5 doubles the odds of getting there naturally.
