It's a Double Diamond slot where you win by landing a winning combination on a single payline and if that combination contains one Double Diamond symbol, your win is multiplied by 2 and if it contains two of them, your win is multiplied by 4 and if you land three of them you win the Top Award of 1600 or 2400 credits, depending on if you are playing a 2 or 3 credit version of each game, respectively.
Double Top Dollar remains an absolute classic that still can be found in most High Limit Rooms.
