Theme and Storyline:
Step into a world bursting with good fortune in Lucky 7! This slot game is all about the luck that surrounds us, with its main focus on the iconic lucky sevens and four-leaf clovers. While these two symbols are central to the theme, you’ll also spot the occasional ladybird and horseshoe, awkwardly squeezed into the mix for variety. The game’s background is adorned with lush green clovers, and in true Irish style, there’s even a rainbow leading to a pot of gold.
While the theme may feel a bit inconsistent, there’s no denying its charm and the sense of fun it brings. Lucky 7 isn’t trying to be a deep narrative experience—it’s just here to make you feel lucky.
Graphics, Sounds, and Animations:
The vibrant visuals of Lucky 7 are a big win. The game features a colorful set of symbols, simple but sparkly animations, and lively movement that really grabs your attention. You’ll find yourself getting caught up in the action, as the symbols dance across the screen.
However, the music feels somewhat like an afterthought. It only plays during the reel spins, and just when you’re getting into the rhythm, it cuts off abruptly when the reels stop. Thankfully, you can turn the sound off if it bothers you.
Gameplay:
Lucky 7 offers a simple five-reel slot setup with 18 winlines. However, there’s one notable drawback: you can’t adjust the number of winlines you play, making the gameplay feel a bit rigid. The pacing can be a bit odd, but the game does offer plenty of options to speed things up or slow them down, including a fast-spin option for impatient players.
Wilds, Bonuses, and Free Spins:
There are a few exciting special symbols to watch out for:
- Wild Symbols: Unlike many other games, the Wild in Lucky 7 only substitutes for “7” symbols, no matter the color. Plus, it adds a multiplier of x2 to any combo featuring a “7” in the main game.
- Colour Bonus Symbol: If you hit three of these symbols anywhere on the last three reels, you trigger the Colour Bonus game. Here, you’ll receive a random number of free spins and be assigned a special “colour” to track. Every clover in that color you land will win you one times your initial bet.
- Lucky Rainbow Bonus Game: Hitting three Lucky Rainbow symbols on the first three reels triggers the Lucky Rainbow Bonus Game. In this bonus round, you’re awarded seven free spins, with all the symbols on the reels replaced by rainbow-colored symbols (plus silver). During this bonus, any combination involving a Wild symbol boosts the winnings by a x3 multiplier for silver, orange, and yellow symbols.
Bet Sizes, RTP, and Variance:
Unfortunately, Lucky 7 is let down by a disappointing Return to Player (RTP) of just 93.05%, which is far below the industry standard. Anything below 96% is considered low, and 93% feels like an instant deal-breaker for most players.
You can adjust your bet per spin, with a minimum bet starting at just €/$/£0.18, and the maximum hitting an eye-watering €/$/£180.00. Though there’s no volatility information available, the frequency of payouts suggests the game might have low to medium volatility.
Conclusion:
Lucky 7 has a lot of potential with its fun bonus games, lively visuals, and theme centered around all things lucky. However, the incredibly low RTP and peculiar betting system from Espresso are major drawbacks. The low return to player rate is a dealbreaker for many players, making it difficult to recommend Lucky 7 for those seeking long-term enjoyment.
Verdict: Not Recommended.
