WILDs:

WILD symbols substitute for all other symbols except scattered "Mystical Diamond Bonus" symbols and "Extra Spin" symbols (during free spins).

WILD symbols appear on reels 2, 3 and 4 only.

"Mystical Diamond" Bonus:

3 scattered "Mystical Diamond Bonus" symbols in any position on the reels imitates the "Mystical Diamond" Bonus and awards 3 free spins.

Free spins are played at the same bet level and number of lines as the initiating game.

Each "Extra Spin" symbol appearing in any position on reel 1 awards 1 additional free spin.

On the first free spin, reel is 2 becomes entirely WILD and is locked in place for the remaining free spins. After the first spin, if no additional free spins have been awarded or all additional free spins have been played, reel 3 becomes a locked WILD reel and is locked in place for the remaining free spins. After the second spin, if no additional free spins have been awarded or all additional free spins have been played, reel 4 becomes a locked WILD reel and remains in place for the remaining free spins.

The bonus ends when 0 free spins remain and reels 2, 3 and 4 are locked, or after 23 free spins have been played.

Different reels are used during free spins. (See the "Mystery Diamond" Bonus Pay Table for symbols and payouts which differ from the main game.)
