Play Jackpot Diamonds for Free

The gemstone theme is one of the all-time classics in the video slot machine world. That is because nothing quite beats the beautiful simplicity of glimmering jewels falling into position to award winning prizes. On the 5 reels of Jackpot Diamonds, players will be treated to a shining display or boldly coloured gems such as pink garnets, purple amethysts, orange beryls, blue sapphires, green emeralds, red rubies and brilliantly white diamonds.

Truth be told, the gemstones presented in this slot machine aren't spectacular specimens in the world of jewel-based arcade games. In fact, this Mazooma slot machine does suffer from being a little bit outdated in comparison to similarly themed games which depict their precious stones in high definition clarity. As a result, the icons of this game appear to be pixilated and somewhat dull. Nonetheless, the gems will spin and glisten whenever a winning formation is achieved.

All of those winning formations consist of three or more identical jewels upon any of the 9 permanently placed paylines going from left to right. This will apply a multiplier to the value of the total bet, depending on how many of which symbol is aligned (see table below). The wagering options are as follows: 40, 50, 80, 100, 150, 200, 300, 400, 500, 800 and 1,000.

Those total bet multipliers in the paytable above may not seem very appealing, since many of the lower valued gems only offer a fraction of the total bet in return. However, whenever a successful spin is spun, players are given the chance to win again with the game's special “Lock and Spin” feature. This will essentially hold the winning gems in position and spin the reels again free of charge, giving punters the chance to add more symbols to the triggered paylines for bigger wins. Should more symbols be added to improve the previous combinations, they will be locked and the feature will continue with another free spin. Each additional winning combination is treated as an extra win and added to the value of the previous win.

This feature will end in one of two ways – until the sequence isn't improved upon or until all 15 reel positions are filled with the same symbol. Should the latter happen, players can expect to receive some very handsome total bet multiplier prizes; a full house of orange gems will multiply the total bet by 10x, purple gems will pay 20x, pink gems offer 30x, blue stones pay 40x and green jewels will fetch 50x. However, should players come across a full house of rubies or diamonds, they will unleash the corresponding progressive jackpots that appear above the reels.

What if we told you that this slot machine offered even bigger base-game wins? Well, players who fancy taking some extra risks can do so with one of two optional “Hi-Roller” game modes, both of will offer higher wins with multiplier trails that increase after every consecutive win in the Lock and Spin feature. The first of these gameplay modes is Hi-Roller Silver, which will increase the total bet by 5x while offering a higher overall RTP of 96%. The Hi Roller Silver will increase the total bet by 10x while giving an even better RTP of 97%.

Jackpot Diamonds is far from being the most magnificent gemstone themed slot machine out there, and the paytable may not seem very appealing at first glance. Nonetheless, the game still serves up some glistening spins with plenty of exciting bonus elements. The main feature being a special Lock and Spin mode which helps players to pile on the winnings with the chance to potentially find one of two progressive jackpots.
