Second Thunder review
Thor faces the beasts of Ragnarok in Second Thunder, a Thunderkick slot whose central trick is a row you cannot see. A hidden feature row can drop Wilds, Scatters and Reel Multipliers onto the board without warning, and in the Bonus Game that row stays fully active. The studio lists 50 paylines on a grid it calls 5x6. The game is rated High, has a 94.2% RTP and pays up to 12,500x the bet.
Thor, Ragnarok and the Wild Field
The setting is Norse: Thor against the great beasts at the end of days. The studio describes a video slot with 50 paylines and a 5x6 layout. Its headline mechanic is the Wild Field feature, which it presents as a way to harness the storm.
The text available to us is short on specifics. It does not explain how the Wild Field is triggered or what it covers on the board, so we describe only what it states and no more.
The hidden feature row
The board carries a feature row that stays hidden. Three kinds of event can strike from it without warning: Wilds, Scatters and Reel Multipliers. The studio gives no sign of a meter or marker that shows when one is coming.
Entering the Bonus Game changes one thing that the studio spells out. The feature row stays fully active for the duration of the round, so the same three events can occur throughout it. The text does not give the trigger, the number of spins or the multiplier values.
Wild Field
The studio's headline feature. It is named as the tool for harnessing the storm, and the studio mentions the hidden feature row in the same breath. The details of how it works are not in the text we have.
Hidden feature row
A row that is not visible on the board. Wilds, Scatters and Reel Multipliers can hit from it at any time. In the Bonus Game the row stays fully active, which raises the number of chances for those events across the round.
Costs and the 12,500x ceiling
Second Thunder has one RTP on record: 94.2%. The house edge is 5.8%, which costs about $58 per $1,000 wagered. The catalogue has no hit frequency for it.
For 100 spins, the average cost is $1.16 at a $0.20 bet, $5.80 at $1 and $29 at $5. The max win is 12,500x the bet: $2,500 at $0.20, $12,500 at $1 and $62,500 at $5. That is the ceiling of a High volatility game, so expect uneven sessions.
Nearby in the numbers
Midas Golden Touch 3 lists 94.16% and 15,000x. Midas Golden Touch: Thunder Pots shows 94.22% and 10,100x, while Temple of Akhet, The Wildos 2 and Hot Potato Battleground each list 10,000x at 94.19%, 94.19% and 94.23%. Greedy Pumpking offers 94.15% and 10,000x. All are rated High. Second Thunder has the second-highest ceiling among them.
Pros
- A hidden feature row can add Wilds, Scatters and Reel Multipliers at any time
- The feature row stays fully active in the Bonus Game
- A 12,500x max win
- Free official demo available
Cons
- A 94.2% RTP means a 5.8% house edge, about $58 per $1,000
- No hit frequency in the catalogue, and little detail on the Wild Field or the bonus trigger
Verdict
Second Thunder bets on surprise. A hidden row throws in Wilds, Scatters and Reel Multipliers, and the bonus game keeps it switched on. It is a High volatility slot with a 94.2% RTP and a 12,500x ceiling, so sessions may be very uneven and the house edge of 5.8% is real. The studio's text is thin on rules, so check the official page, or try the free demo, before settling on a stake.
