The Lock It Link Diamonds video slot was originally designed for real money play in live casinos. However, WMS and Scientific Games have recently ported it over to the online casino world, making it available in a play for free version at Play4Fun social casino sites. The original version, which was available in a variety of low limit and high limit versions in live venues, used a luxurious theme that featured a mansion setting and a blue/purple color palette that lends a feel of cool elegance to the machine.
The base game uses a 3×5 layout, but you won’t have to worry about paylines. Instead, this is a 243 ways to win machine, with every left to right combination scoring prizes for players. Small awards are given for matching three or more of each of the card game suits — clubs, spades, and so on — across the reels. Larger prizes are attached to martini glasses, rings, watches, and dice, with a lovely woman offering the highest payouts of all. Meanwhile, a set of gold bars serve as wild symbols. These are stacked, and if any part of a stack should take part in any winning combination, the symbol will shift to cover the entire reel.
There are two types of special icons gamblers will want to look out for when you play Lock It Link Diamonds. The first, naturally enough, are diamonds, which serve as scatter symbols. Hit any three on the screen, and you’ll trigger a free spins game. But the real bonus round comes when you can hit three or more hearts on the same row on any given spin. These hearts come in two different types: red ones that feature credit prizes worth up to 100x your bet, and golden hearts, which feature one of four special prizes, including two small bonuses and two larger progressive jackpots. The jackpots can only appear on the third reel, while the rest of the reels will only trigger the Minor and Mini Bonus gold hearts.
Once you’ve successfully triggered the feature, the hearts on the triggering row will move together if they aren’t yet adjacent. These symbols are now â€œlinked.â€ You’ll now get free spins in which only hearts can potentially appear on the reels. Every time a heart appears in a position that is adjacent to your linked group, a few things will happen. First, that new icon (and any others that were previously unconnected, but which can now be linked) will now show a prize amount on it. In addition, all existing hearts will have their prize levels increased.
Finally, each new link will reset your spin counter, allowing the mini game to last even longer. This feature continues until either the entire screen is covered in heart symbols, or if you run out of spins without linking any new symbols. In either case, at this point, you will collect all of the coins that appear on screen, along with any of the bonus prizes or jackpots that you revealed along the way.
