Configurations:

WILDs:

WILD symbols substitute for all other symbols except scattered BONUS symbols and only appear on reels 2, 3, 4 and 5.

Free Spin Bonus:

3, 4 or 5 scattered BONUS symbols trigger the Free Spin Bonus and award 10, 12 or 15 spins respectively.

When the free spins begin, the multiplier for each symbol is set to 1x. After each spin all pays are evaluated with the current symbol multipliers. In addition, each winning combination increases that symbol's multiplier. Multipliers start at 1x and go to 5x, 10x, 15x, 20x, and cap at 25x. (This applies to all winning combinations except for five Treasure Diver symbols which pay at 1x.)

The multiplier for any symbol can only increase one time per spin. The multipliers increase whether or not the payline is active.

3, 4 or 5 scattered BONUS symbols during the bonus award 5, 7 or 10 additional free spins.

During free spins an alternate set of reel is used, except that the Coins symbol does not appear on the reels. Winning combinations for these reels are identical to the base game.

During free spins the bet per line and the active paylines remain the same as the spin that triggered the bonus.
