Features of Double Diamond Slot Machine

The secret to setting a realistic expectation and possibly developing a winning Double Diamond strategy is understanding how slots work. Double Diamond is a traditional slot in the 3-reel category. It keeps everything simple in both design and gameplay while offering one of the best payback percentages and jackpots. The unique features found below heighten the excitement for both newbies and professionals.

Return to Player (RTP)

In theory, RTP means the payback percentage or all money wagered that the slot returns to players over time. The industry standard is around 95%, which means if a player bets €/$100, the machine will return €/$95 to the players over a long period. With an RTP of 95.44%, Double Diamond aligns with industry expectations.

Medium Volatility

A high volatility suggests less frequent big wins, while a low volatility suggests more frequent small wins. Double Diamond’s volatility is somewhere in the middle, suggesting a balanced chance for both small and big wins.

Fewer Symbols

Compared to other slot machines, Double Diamond has fewer symbols, which means a higher chance of landing a winning combination. The icons on the slot are 7z, BAR, Double Bar, Cherries, Triple BAR and, of course, Double Diamond. The last one is the most important symbol, which is where the name of the game was derived. Below are the winning combinations:

• Landing three Double Diamond symbols pays 1,000x your bet
• Landing three 7s symbols pays 80x your bet
• Landing three Triple BARs pays 40x your bet
• 25x your bet by landing three Double BARs on the payline
• 10x your bet by landing three single BARs on the payline
• Landing three, two and one Cherry pays 10x, 5x and 2x your bet respectively
• Landing three of any BARs pays 5x your bet

Likewise, it is up to the hosting casino to set the maximum wager. Regardless of where you choose to play Double Diamond, the steps will remain the same as follows:

What is the Double Diamond Strategy Model

The best slot tip anyone can give you is that you cannot predict the outcome of each spin. The outcome of every spin is random. However, what you have control over is the size of your winnings – and this is where you should invest your strategy.

We would like to highlight two different Double Diamond slot machine strategies. The first strategy is for those who are playing for the thrill of watching rolling reels. Placing smaller bets (like sticking to the minimum bet size) will extend your playtime if you have a slim budget.

For players focused on winning big, the reverse is the right strategy. Pump up your wager to the maximum allowed by the casino. That increases your chance of hitting the sweet jackpot. For example, if you bet the maximum €/$250 and your spin lands triple Double Diamonds, that bet will be multiplied by 1,000 which gives you €/$250,000.

Final Spin and Bonus Round Tactics

Most of the new free slot games have free spins and bonus rounds – and that is where Double Diamonds differs. There is neither in this game. This is a feature that was carried over from the traditional game to the online version.

Instead of free spins, Double Diamond has a re-spin option where players can roll the reels for free after hitting a winning combination. This feature increases the chance for larger payouts, especially for those using the maximum bet strategy. Free spin is not the only feature found in new slot games that is missing in Double Diamond.

Scatter symbols are also missing in Double Diamond. When playing with real money, set the maximum bet and land three Double Diamonds on the payline to activate the progressive jackpot.

A sort of bonus that comes with Double Diamond is the autoplay feature which allows you to set the number of spins you want to play and sit back and watch it automatically roll that number of times.
