Most countries have their own law about paying taxes on casino winnings. If you are not sure of percentage or limits on tax deduction on winnings, please ask your local tax authorities.
There's only one way to get a free spin in this game is that you need to charge the bar either the blue color on the left or the red color on the right. To fill a bar, you need to land on the red and blue potions.
There are three charges on the blue vial. The first charge will give you 1 free spin. The second charge will change all the higher paying symbols into wilds, and the fully charged will provide 5 free spins with wilds at reels 1, 3, and 5. To do this, you need to land on blue vials and fill up the bar.
The red vial is similar to the blue one, but its effects are different. The first charge will give you 3 free spins with 3x of every win per spin. The second charge will offer 5 free spins, and you can also pick two of the highest symbols and turn them into wilds. And the third charge will also provide 5 free spins while adding one sticky wild during those 5 free spins.
Yes, this game also offers a bonus round in which it is triggered by landing three wizard symbols. It will take you to a board where you fight the wizard with cards. Each time you defeat a monster card, you will receive prizes, but it will depend on the kind of monster you beat.
