Devils Lock — RTP, volatility and max win

Bluberi sets Devils Lock in hell's treasure vault: the devil guards coins, crowns, diamonds and piles of cash among red flames and deep dark blue. Value symbols add up their amounts, a collector sweeps them into a pot, and free spins extend the treasure hunt.

The theme pairs hellfire with riches: the devil as guardian, plus gold coins, crowns, diamonds and treasure chests in red and dark blue. Five reels of three rows form the 5×3 grid, crossed by 40 paylines. You need at least €0.66 per spin and can go up to €132, so the entry bet is noticeably higher than on many other titles. Bluberi released Devils Lock on February 16, 2023, and the figures were last checked against the source on June 17, 2026.

The 5×3 grid carries 40 paylines. A coin or crown combination pays when it builds from the left along one of those lines; with so many lines packed into fifteen positions, almost every reel stop offers several chances at a combination. The wild fills gaps in a line. Value symbols never count on lines; their cash comes through the collection feature. How much a line returns depends on the symbol and the bet you set from the €0.66–€132 range.

At the core of Devils Lock are value symbols that each carry a cash amount. When several land, their values add up, and a collector symbol sweeps the total into a pot that pays out as a win. The free spins carry the same mechanic into a round of their own, where pots can fill without a new stake. The wild fills missing positions on the lines and keeps the base game ticking between collections.

Since Devils Lock carries its collection mechanic into the free spins, continue with the other inferno slots with free spins.

RTP 94%, lower than 92% of the 400 Inferno slots. Background: how RTP works on a slot. Volatility Low, like 6 of the 180 slots in the Hell & devil theme. Background: what slot volatility means. Max win 2,013× (€265,716 at the highest stake). Background: what max win means on a slot. Hit frequency 32.35%: roughly one spin in 3 wins.

At 94%, Devils Lock is among the lowest-paying inferno slots. Low volatility is rare in the hell range and suits a collection mechanic that gathers many small amounts into one pot. Capped at 2,013×, it falls short of the median for the selection.

Because Devils Lock comes with an RTP range and even its published figure is low, the RTP comparison of inferno slots shows which titles pay back noticeably more.
