Rules of the game

The game has 81 ways to win.
The winning ways reward matching symbol combinations in any position on adjacent reels, starting from the first reel on the left.
The Mystery Symbols give a prize in any position on the screen, but only during the Mystery Roll feature.
Only the longest combination of symbols is paid out per way to win.
The gains from the different ways of earning add up together.
Winning combinations and payouts are calculated according to the Payout Table.
The maximum possible winnings in a round of play are 250000.00 EUR.
Wild Symbol
The Wild symbol substitutes for all symbols except the Mystery symbol.
Mysterious Regiro Function
The presence of 4 or more Mystery symbols in any position on the reels activates the Mystery Spin feature.
The Mystery symbols that have activated the Mystery Spin feature will retain their position on the reels throughout the feature.
If new Mystery symbols appear on the reels, they will also remain in place.
During the Mystery Roll feature, Mystery symbols can award a value of 1x to 10x or have one of two additional functions:
The Mystery multiplier symbol, which gives values from 1x to 10x, is further multiplied up to x10.
The special Mystery symbol awards randomly chosen mystery prizes from 10x to 100x.
The Mystery Spin feature ends if no new Mystery symbols appear on the reels during the spins or if all 12 positions are filled with Mystery symbols.
The earnings from the Regiro Misterioso performance are added up and awarded at the end of the performance.
The Mystery Regiros are played with the same bet as the round that activates them.
Risk
You can bet on the Risk feature up to 125000.00 EUR.
