Lock It Link Diamonds Slot

Lock It Link Diamonds Slot Machine

It is often said that diamonds are eternal, and there is some truth to that: diamonds are among the toughest materials available, making them highly suitable for various industrial applications. Their resistance to contamination is remarkable, yet even minute imperfections can imbue each diamond with a unique color. Moreover, diamonds are admired for their exceptional beauty, which is why they are a preferred choice for jewelry, especially for engagement rings.

These exceptional qualities have contributed to the high value of diamonds, establishing them as a universal symbol of prosperity and achievement. This makes diamonds an ideal theme for Lock It Link Diamonds, a new online slot game by WMS that prominently showcases these exquisite gems. Part of the renowned Lock It Link series initially popular in land-based casinos, this game boasts an engaging bonus round where your rewards can escalate through heart connections on the screen.

A Girl’s Best Friend

The Lock It Link Diamonds video slot was initially created for wagering with real money at brick-and-mortar casinos. However, WMS and Scientific Games have recently introduced it to the realm of online casinos, offering a free slots version on Play4Fun social casino platforms. The original version, available in various low and high limit formats in physical venues, featured a luxurious theme set in a mansion with a cool blue and purple color scheme, evoking an aura of sophistication.

The game employs a 3×5 layout without traditional paylines. Instead, it functions as a 243 ways to win slot, rewarding players for any left to right combination. Matching three or more card suits—such as clubs and spades—across the reels awards modest prizes. Higher rewards are associated with symbols like martini glasses, rings, watches, dice, and a graceful woman who offers the highest payouts. Stacked gold bars act as wild symbols, expanding to cover entire reels when part of a winning combination.

Don’t Break the Chain

When playing Lock It Link Diamonds, players should keep an eye out for two special symbols. The first are diamonds, serving as scatter symbols. Landing three diamonds triggers a free spins round. The main feature, however, is activated by landing three or more hearts in a row during a spin. These hearts come in red, offering credit prizes up to 100 times your bet, and golden varieties awarding one of four special prizes, including two smaller bonuses and two progressive jackpots. The jackpots can only appear on the third reel, with the other reels activating the Minor and Mini Bonus golden hearts.

Once the feature is initiated, the linked hearts move together if not already adjacent, becoming “linked” symbols. Subsequent spins comprise only heart symbols. Whenever a heart appears adjacent to the linked group, new icons display prize amounts, enhancing the prize levels of existing hearts. Each link resets your spin counter, prolonging the mini-game. This feature continues until the screen is filled with heart symbols or spins are depleted without creating new links. At this point, players collect all the coins shown on screen, along with revealed bonus prizes or jackpots.

Locked On Target

The free Lock It Link Diamonds slot on the Play4Fun Network may not offer real cash rewards like its live counterpart, but it is still an enjoyable experience. The innovative bonus round is a standout feature, adding excitement and suspense as players aim to extend the feature and increase rewards on each bonus spin. While the theme is somewhat generic and features are limited, the mini-game and the 243 ways to win action make it an entertaining game worth trying in both real and play money modes.
