SYMBOLS AND SPECIAL FUNCTIONS
CHAIN REACTION

LIGHTNING
Thor appears to summon Lightning. Lightning can remove all low-paying symbols or transform random symbols into matching symbols or WILD!
HAMMER
Thor appears and throws his hammer. He can eliminate a random number of 2x2 symbols and replace them with high-paying symbols, or hit random rows or reels to win prizes!
UNLOCK FREE SPINS
There are 9 inactive squares in the center of the slot. These are unlocked by adjacent winning combinations. Destroy the 8 outer squares in a Chain Reaction to unlock either VALHALLA FREE SPINS or MUSPELL FREE SPINS. When triggered, the player receives either 3 to 10 random Free Spins or exactly 20 Free Spins.
FREE SPINS FROM VALHALLA
Thor clears all the squares and fills the slot machine with Golden Shields until the FREE SPINS end. The Golden Shields that appear will be locked until the Free Spins end. When the FREE SPINS end, each shield reveals a random Bet Multiplier! The possible multipliers that can be revealed are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 25, 30, 35, 40, 45, or 50x.

LAVA RAIN
The LAVA RAIN falls randomly during the MUSPELL SPINS and destroys one or more types of symbols, except the high-paying symbol (Golden Hammer) for a free spin.
RIVER OF LAVA
The RIVER OF LAVA creates identical symbols on connected rollers.
WILDCARD
Replaces all payment symbols.
AWARD GROUPS
A group consists of symbols of the same type that are adjacent horizontally or vertically. All groups of 5 or more identical symbols award a prize.
HOW TO PLAY THOR'S LIGHTNING
Total Bet
The total bet equals the total of the bets per line. It can be adjusted at any time using the “+” or “–” buttons.
Turn the rollers
If you're playing on a desktop computer, click the Rotate button or press the space bar to rotate.
Automatic game
Press the AUTO button to start the game automatically with the currently selected bet. Select the total number of spins you wish to play from the Total Spins drop-down menu.
More automatic spin settings
Select your loss limit. Auto Spin will stop on the last spin before reaching the loss limit. Your Auto Spin's loss limit must be higher than your stake.
The AUTO SPINS dialog expands when you select MORE AUTO SPINS SETTINGS. From here you can select other criteria for stopping AUTO SPINS, including: stop if the single prize exceeds a certain amount, and stop on a Bonus feature.
Jackpot Game
Win one of the offered jackpot levels when three or more jackpot symbols appear on the reels or the jackpot is triggered by a game feature. The chances of winning a jackpot increase in correlation with the size of the bet played. The jackpot is triggered randomly and can be won by playing any of the related jackpot games. To win the jackpot, the player is not required to make any decisions other than spinning the reels. The bet amount cannot be changed during free spins. Internet connectivity issues may cause delays in jackpot messages or updates, but these do not affect the actual jackpot prizes. It is not possible for two players to win the same jackpot. In the event of two jackpot wins occurring close to each other, the jackpots will be awarded in the corresponding order. Due to connectivity issues, the displayed jackpot value may differ from the actual jackpot value. The jackpot may be temporarily deactivated; when this occurs, all contributions will stop. The amount of the jackpot available upon reactivation will be the same as before deactivation.
The rules for suspending the Jackpot and allocating Jackpot funds are defined by each Operator according to their own criteria.
Part of the bet for jackpots: 3%
Timed Jackpot
The scheduled jackpot is a progressive jackpot that guarantees payout before a set date and time. The prize increases with the bet contributions of each spin in a jackpot game, and the closer the prize is to the guaranteed payout deadline, the greater the chance of winning it. The odds increase to 100% when the time for the last guaranteed payout is reached. Once the jackpot has been won, a new scheduled jackpot appears, and the process repeats, with a deadline set for the next guaranteed payout. The jackpot can be triggered and won with a single spin by a single player. The jackpot has no maximum value, but it must be won before the specified date and time. If another player wins the jackpot, a notification will appear on the jackpot panel. Once a player has won, the amount will be transferred directly to their wallet, even if they are in the middle of a bonus spin.
Daily Jackpot (time)
The current initial value is: €0, The next minimum initial value is: €0
General types of games
Consult the payment menu in the game's paytable if you are unsure of the game type.
The values associated with each symbol, which are displayed on the slot machine screen or on the Symbol Prizes pages in the Payouts menu, represent bet multipliers and not credits.
The prize value for a payline is equal to the total amount wagered divided by the number of paylines and multiplied by the multiplier symbol shown in the paytable. If multiple wins occur on different lines, the total prize is accumulated. If more than one win occurs on the same payline, only the highest win is counted. Each individual payline can only pay once per spin.
Example: The total bet is 2 and there are a total of 20 paylines. The multiplier for a 5-match is 300. The prize for a payline with this multiplier and that number of matches would be: 2 / 20 * 300 = 30.
The prize value for a payline in a Multiline game is equal to the amount wagered multiplied by the multiplier of the symbol shown in the paytable. If multiple prizes are won on different lines, they are added together. If more than one prize is won on a single line, only the highest prize is paid.
Example: The amount wagered is 2. The symbol multiplier for 5 symbols is 20. The prize for 1 payline with this symbol and this length is calculated as follows: 2 * 20 = 40.
The prize value for a shape or group in a shapes or groups game is equal to the stake multiplied by the symbol shown in the paytable. If multiple prizes have been won in different shapes or groups, the total value of the prizes is added together.
If more than one prize occurs in the same line or group, the highest value prize will be paid.
Example: Total bet = 2. Multiplier symbol = 2. Winnings = 2x2 = 4.
During the Free Spins bonus rounds, the game uses a different set of reel strips.
If there is a Scatter symbol in the game, all prizes will be paid out, in addition to the prizes from any other symbol that occurs on the same spin.
When participating in a Scatter prize game, only the highest winning combination per symbol is paid out.
