The play area appears at first as a standard 5x3 grid with 3 more, shadowed rows above it. Every time you win, you will trigger a respin and the play area will expand upwards by a single row, sending sparks flying. The play area can expand up to a maximum of 6 rows and 10 more paylines will be added with each expansion for a maximum of 50 paylines.
Once the grid is expanded to its full 5x6 reel size, a multiplier trail will activate. You will start with a 2x multiplier and each consecutive win you land will increase it to 2x, 3x, 5x, and 10x.
Scatter symbols only appear on reels 2, 3, and 4, and at least 3 are required for a payout. These pay individual coin values with the amount depending on which row they appear on. Scatter symbols on rows 1, 2, 3, 4, 5, or 6 pay 1x, 2x, 4x, 6x, 10x, or 20x your bet, respectively.
