The Diamonds RTP is 96 %, which makes it a slot with an average return to player rate. For a better return, check out our page on high RTP slots.

RTP stands for Return to Player and describes the percentage of all wagered money an online slot returns to its players over time.

For example, a slot machine like Diamonds with 96 % RTP pays back 96 cent for every $1. Since this is not evenly distributed across all players, it gives you the chance to win high cash amounts and jackpots on even small deposits.

Diamonds Review

Diamonds is a jackpot slot from Big Time Gaming that launched back in 2013, with the design having clearly not been enhanced since. As a unique version of the Diamonds Are Forever slot from Pragmatic Play, Diamonds comes with 5 reels and 40 paylines. We found a unique 4-3-4-3-4 reel formation, which helps the game stand out from traditional 5×3 slot setups. With rubies, emeralds, and diamonds, you can win up to 1,000x your bet. With simplistic gameplay and a colourful design, our Diamonds review will demonstrate just why the game has been a popular slot for so long.

Diamonds Free Spins

Unfortunately, there are no free spin features with the Diamonds slot. However, as we will discuss below, there are a few bonus features to speak of, which help make up for this. This demonstrates once again that Diamonds is a little different from other BTG slots, with the likes of Danger High Voltage and Beef Lightning coming with between 19-24 free spins, as well as free spins variations.

More Features & Wager Limits

The Reaction Bonus helps to make up for the lack of free spins. This feature is triggered when landing 5 icons of the same colour in a line. This is known as a “Reaction”, with multiple potentially occurring at the same time. In fact, we experienced as many as four during testing.

Each reaction will also add 1x to the multiplier to the right of the reels, which we found was applied to the next set of reactions. Upon the Reaction Bonus ending, the multiplier is reset. Meanwhile, in the event of diamond icons landing in a line of 3, 4, or 5 on a payline, the Mini, Midi or Maxi jackpot will be triggered.

When playing Diamonds, we found a minimum bet of $0.40, with the maximum stake per spin being $400! As a result, we feel that Diamonds is a slot well suited to high rollers. The maximum win is 1,000x your bet, or up to $400,000.

Diamonds Slot Design & Music

Green, red, and blue gems are displayed, with the overall design being simple yet effective. While the grey background and reels are not the most exciting, we found that things quickly livened up when bets were placed. The soundtrack is surprisingly upbeat for what is a relatively simple slot. However, we found that the beat tied in well.

Review Summary

While gem-themed slots are not to everyone’s taste, we certainly enjoyed this offering from Big Time Gaming. Diamonds is undoubtedly unique, with winnings being paid out on both shape and colour combinations. There is even an auto-play feature, which can play 25 games for you. The maximum winnings, minimum and maximum bets and bonus features should cater for most players, with the lack of free spins being the only real limitation in our opinion.

Tried and tested by eCogra, Diamonds is completely fair, with our experience having been very much positive. Whether you are looking to play for free or for real money, all players are well looked after, with Diamonds certainly being more than just a girl’s best friend.
