The Lock It Link feature is the real star in Lock It Link Diamonds, bringing a hold-and-respin bonus with a shot at four jackpots. You play with 50 fixed paylines, a 5×3 grid, low volatility, and a 96.02% RTP. Your top possible prize is 5,000x your spin.
What pulled me in was how quickly the bonus round can turn, one spin can fill the reels with hearts for a huge win, or just fizzle. The base game feels pretty steady. The action picks up when you land three Diamond scatters and choose between free spins or going after the Lock It Link. If you like clear jackpot chances and a glitzy look, try the demo. The bonus can swing everything.

Lock It Link Diamonds uses a 5-reel, 3-row layout and has 50 fixed paylines. Wins pay left to right only, and there’s no way to change the number of lines. The minimum spin amount starts at 0.50 and can go up to 45, depending on the casino.
The key mechanic is the Lock It Link feature, which opens up in two ways:
During Lock It Link, hearts lock in place showing cash values or jackpots, and respins continue as long as you get another heart.
There’s also a 2x multiplier on base game wins when more than one wild appears in a win. Free spins use special reels with more Heart symbols and wild-based multipliers every time you win. Everything works equally on desktop and mobile.
Lock It Link Diamonds features a 96.02% RTP, which is above the online slot average. Over time, this returns $96.02 for every $100 played, but any session can win or lose much more.
Volatility here is low. You’ll see plenty of frequent, smaller wins. The bigger swings: and real thrills: happen in the feature rounds or hitting jackpots. This makes Lock It Link Diamonds a good pick if you prefer consistent play with occasional big features. For other high RTP slots, see our high RTP slots page.
All payouts below are based on your total spin.
| Symbol | 3-of-a-kind | 4-of-a-kind | 5-of-a-kind |
|---|---|---|---|
| Gold Bar (Wild) | – | – | 150x |
| Lady | – | – | 100x |
| Dice | – | – | 90x |
| Watch | – | – | 75x |
| Ring | – | – | 50x |
| Glass | – | – | 50x |
| Club suits | – | – | 20x–30x |
Gold Bar is wild, substituting for all symbols except scatters and hearts. When more than one wild drops in a win, your prize is doubled. Lady is your highest-paying regular symbol, with dice, watch, ring, and glass trailing behind. Card suits pay least.
Diamond scatters only show up on reels 2, 3, and 4. Get three and you’ll earn 5x your spin, then choose between free spins or the Lock It Link feature. Heart and Gold Heart symbols trigger Lock It Link, and Gold Hearts can reveal jackpots during the bonus.
Lock It Link Diamonds comes with four fixed jackpots, all available in the Lock It Link bonus. Gold Heart symbols may show Mini (40x), Minor (100x), Major (2,000x), or Grand (5,000x) prizes. Collecting Gold Hearts labeled with jackpots instantly adds that amount to your total prize.

Every spin runs on a random number generator, so nothing changes the odds. Running the demo showed me the Lock It Link round sometimes triggers in clusters, but you can easily spin a while before landing another.
I’d keep spins low until you see how the bonus drops, since jackpots only come from the feature. Autoplay is handy if you want to speed up the action, but always put a cap on your session.
Each round is its own shot.
Lock It Link Diamonds features a glossy, jewel-focused look with 2D symbols. The reels sit in front of a neon-lit casino scene, plenty of lights, lots of shine.
When you win, symbols pulse and flash. During the Lock It Link bonus, the hearts light up each time you land a new one. The soundtrack grabbed my attention right away with lively casino tunes and punchy effects. As heart symbols stack up, the effect sounds ramp, it’s catchy.
All in, the visuals and sound boost the game’s fast-paced, upbeat feeling.
