Wild, Multiplier Symbol
The Double Diamond symbol in the Double Diamond slot machine game is a wild, multiplier symbol. This means that the Double Diamond wild symbol substitutes for other symbols to complete winning combinations and multiplies the payout.
One Double Diamond wild symbol "doubles" the payout of any winning combination it completes if it acts as a substitute symbol.
Two Double Diamond wild symbols "quadruple" the payout of any winning combination they complete if they act as a substitute symbol.
Get three Double Diamond wild symbols on the payline and you win the Jackpot of 2,500 credits!
Multiple Double Diamond symbols on an enabled payline create winning combinations, as shown in the "Regular Payout Schedule".
The Double Diamond symbol winning combination payouts are not multiplied.
Note: Only one winning combination is paid out per payline. If there is more than one possible winning combination on a payline, you are paid out the value of the highest combination only.
