A game that will surely make happy those nostalgic for the slot “retro” machine-style titles of the past decades is Double Diamond from IGT. The very essence of the slot machine: three reels and a single line of the episode in the middle of the screen. A simple game but it was able to thrill millions of players. No coincidence that the Double Diamond slot machine is often cited as the queen of the slot machines. The online version of this famous game reflects perfectly the traditional arcade version. The sounds seem mechanical rather than electronic, while the color definition is obviously improved by modern technology. The symbols are the classic ones: from 7 written in fiery colors, red cherries and of course without neglecting the written BAR in its three variations (1, 2 and 3 written). Obviously there is a special symbol, in this case one depicting two diamonds, from which it derives the name of the game. This symbol can replace any symbol, doubling the payout even when this happens. Also, if the player will realize a combination of Wild symbols, he will win a payout of 1,000 coins, also known as the jackpot of the game. In its simplicity, Double Diamond is still a very fun slot game and without any features or bonuses to interrupt the gameplay, users can easily enjoy this classic slot machine for long periods of time. The improved graphics may not actually rival the new modern video slots but even with one payline, the winnings can get quite substantial given the fact that this game has a high payout percentage of 95.44%. The size of the bet can also vary quite a lot and players of different bankrolls will be able to make the most out of the slot, no matter if they bet a few dollars or a few thousands.
