Lock a Luck review

If Lock a Luck doesn’t look like there’s much going on from the surface, that’s because, well, there’s not. It’s not feature-heavy and it doesn’t stray very far from the base game… but it’s the locked reel feature that will create some thrills. We actually found this online slots game to be very similar to NetEnt’s Twin Spin slot, which functions in a very similar way.

This is a very easy slot to get your head around, but we’ll go through everything in detail below to give you a full idea of what to expect.

  • Release date: 12 November 2019
  • Game: Lock a Luck
  • Game info: Five reels, three rows, 243 paylines
  • Bet levels: £0.20-£60
  • Maximum win: 1,333x
  • Special features: Locked reels
  • Jackpot: No
  • Return to player: 96.37%
  • Volatility: Medium

Lock a Luck slot by Microgaming & All41Studios

Lock a Luck bonus features

It’s rare that we don’t have much to say, but there’s really not an awful lot going on in Lock a Luck. it all comes down to the locked reels feature, which is where you’ll have the chance to score the maximum prizes.

Locked reels

On every spin, you’ll see two of the reels lock up to share the same symbols, giving you extra chances of completing one of the 243 paylines. As you keep spinning, the reels can randomly expand to link up with more – and if you’re lucky, the entire five reels can lock up during a spin. This is what will award the maximum payout, so it’s worth waiting around for.

Free spins

Free spins would have made a fun addition to this slot, but unfortunately, they were not included.


Again, there are very limited features in Lock a Luck, and they don’t include a wild symbol.

Lock a Luck jackpot

There also isn’t a jackpot prize in this slot, but if you manage to link up all five reels together, you’ll have the chance to play for the maximum prize.

RTP and volatility

A medium volatility slot, Lock a Luck sees a mixture of high and low wins hit semi-frequently. The return to player is also on the higher side at 96.37%.

Lock a Luck on mobile

Being such a simple slot, Lock a Luck is actually a great option to play on mobile, since there’s not much happening on the smaller screen anyway.

What does John have to say?


A simple yet fun slot. While I would have enjoyed more features, the locked reels can keep things pretty thrilling.
