How does Devil’s Lock work?
Devil’s Lock is a 5-reel, 3-row Bluberi slot that pays on 40 lines, with a devil wild on the centre reel that collects coin prizes. Coins carrying cash values or jackpot labels can land on the reels, and when the devil wild appears it unlocks them and collects their prizes. That collect mechanic is where most of the game’s value sits.
What jackpots and free spins does it have?
Coins can carry one of four jackpots: Mini, Minor, Maxi and Grand. The free spins round adds sticky wilds, which stay in place and keep collecting.
Which RTP version should you look for?
Bluberi offers Devil’s Lock in several RTP versions, from as low as 88.5% up to 95.5%. The version makes a real difference to your long-term return, so open the game info and look for the highest one.
How much can you win on Devil’s Lock?
The top win is 2,013x your bet. We worked out what that means in cash at three stakes:

Devil’s Lock vs other cash-collect slots
Devil’s Lock belongs to a popular group of slots where special symbols collect cash and jackpot values. Its RTP range is wider than most, so the version your casino runs matters more here.
| Slot | Provider | RTP | Top jackpot |
|---|---|---|---|
| Devil’s Lock | Bluberi | 88.5% to 95.5% | Grand |
| Gold Blitz | Fortune Factory Studios | 96% | 2,500x (Mega) |

Who is Devil’s Lock for?
It suits players who like a simple goal on every spin: land coins, then hope the devil wild arrives to collect them. The sticky wilds in free spins make the bonus the best chance at a big collect. The catch is the RTP: at 88.5% you would lose about $115 per 1,000 spins at $1 on average, against about $45 at 95.5%. If you cannot see the RTP or it is low, play one of the alternatives above instead.
