There are 30 fixed paylines in this 5x3 game but the game actually uses cash values for the bet and for the paytable, as this allows you to play for as little as €0.05. You simply adjust your bet by clicking the plus or minus sign, and the maximum value is €1000. The large Spin button is on the right, and there are also Turbo and Autoplay options available. Autoplay, with Turbo enabled, is likely the best choice as the spins are somewhat unnecessarily slow. Main game and paytable There are two girl miners that are the main characters and symbols in the game, and they can appear separately or together on the same picture. They're always three symbols tall while all the other symbols are the standard ones. The girls pay 5x or 6x your bet for five-of-a-kind, and the three medium-win symbols pay 4x, 3x and 2x respectively. There are also four card symbols which will serve a purpose of getting you a portion of your stake back, or you'll get a small profit if lucky. There is a non-paying Wild that appears on reels 2, 3 and 4. Bonus features Three or more Scatters activate the free spins. You'll always get 8 free spins regardless of the number of Scatters, but will also get a cash prize up to 50x total bet to reward you for landing them. During the free spins feature, both Girl symbols will upgrade to a Golden Girls symbol that shows two of them together on the same symbol. Six or more Firecatcher symbols, which appear on your reels with respective cash prize values shown on them, trigger the Firecatcher Feature. The prizes can be from 1x to 200x your bet on each symbol. When the feature is triggered, the triggering symbols are held while the others re-spin 3 times. If you land at least another Firecatcher symbol, that symbol is held and the re-spin count is reset to 3. Feature ends when you don't land a new Firecatcher symbol, and if you land all 15 then you'll win the non-progressive Scorcher Jackpot of 10,000x your bet. If you don't win a jackpot, you win the sum of cash values on Firecatcher symbols that you landed. The entire Firecatcher Feature is played on a separate board where all the other symbols are greyed out.
