The Microgaming classic online slot game Double Wammy is a standard 3 reel, 1 payline and 3 coin casino slot machine. It is simple enough to play this online slot game because players must only line up 3 like symbols on the payline to win. Coin sizes range from $0.25 to $5 and the maximum bet is $15. The 6 regular symbols can produce 9 winning combinations. The Double Wammy is a wild, doubling symbol which replaces any other symbol to complete winning combinations. One Double Wammy symbol doubles and two Double Wammy symbols quadruple the payout of any winning combination.

Winnings paid out on Double Wammy depend on the symbols displayed on the payline and on the wagered coin size. So, for a 3 coin bet, three Double Wammy symbols pay the top jackpot of 2,500 coins x $5 = $12,000. Three Double Wammy symbols pay only 1,600 coins for a 2 coin bet and 800 coins for a 1 coin bet. Three Red Seven symbols on the payline win 240 coins for the maximum $15 bet. So, the next highest payout is a combination of 1 Red Seven symbol and 2 Double Wammy symbols which pays out 240 coins x 4 = 960 coins.
