Second Thunder
RULES OF THE GAME
Note: The Second Thunder slot machine is referred to as Second Thunder, "the game," or "the game."
- Second Thunder is a 6x5 video slot featuring accumulator symbols, a Wild Field feature, and a row of features including reel multipliers, Wild introduction, and bonus symbols. The game also includes a bonus round with free spins and re-triggers. The theoretical return to player (RTP) is 94.20%.
- The activation key launches a game turn to which the selected betting level is applied.
- The autoplay feature makes the game continue automatically until the number of turns selected on the autoplay settings page is completed. This feature may not be available.
- All payouts and prize combinations in the game are according to the payout table.
- All prizes are presented and paid at the selected venue.
- The longest prize per payline is only paid if it occurs in a sequence from left to right without spaces, forming one of the combinations indicated in the pay table.
- The wild symbol substitutes for all symbols except the scatter symbols. It appears as a single symbol on the cylinders or as accumulations of 2 or 3 when entered from the function row.
- The Wild Field feature is activated when wilds land on two or more reels, creating a rectangle that transforms all symbols within it into wilds. The field can extend up to six reels. Extra Play can also be triggered when a wild field is present.
- The Feature Row is located above the reels and can be triggered randomly during base game spins. When activated, it includes at least one Wild or Scatter symbol and may also contain x2, x3, x5, or x10 multipliers. Reel multipliers are only activated when the Feature Row is active and apply to all wins on its reels. If multiple multipliers appear in the same Feature Row and are part of the same winning payline, their values are added together before being applied to the prize.
- 3 or more Scatter symbols trigger the bonus game with 5 free spins. Each additional Scatter symbol adds 2 more spins. The feature row is triggered on every spin during the bonus game. Landing 3 Scatter symbols during the free spins grants a full replay.
- The bet cannot be changed during the game turn.
- In case of failure in the game, all bets and payouts will be voided.
- All prizes won during a game turn are added together and displayed at the end of the turn.
- The maximum total bet multiplier for a game round is 12500. If this limit is reached, the game round will end and no further prizes will be paid.
- A BET+ option can be activated at a cost that is a multiple of the current stake. When activated, each spin guarantees the specified effect until deactivated. All results from BET+ activation are rewarded according to the payout table and in relation to the size of the base stake. The BET+ feature may not be available in all markets.
- Bonus Boost: Each spin has twice the chance of triggering the bonus game, and costs 1.5 times the base bet. The theoretical return to player (RTP) for this mode is 94.19%.
- Bonus Plus Boost: Each spin has a 5x greater chance of triggering the bonus game, and costs 3 times the base bet. The theoretical return to player (RTP) for this mode is 94.19%.
