Dragons’ Lock is built around collecting keys to unlock three prize chests and then open them. Only chest one is available at the start; five Dragon Keys unlock chest two, and five more unlock the third. This separates progression from immediate settlement: early keys can remove locks before later keys reach the higher prize tiers. On a five-reel, four-row grid with 40 lines, keys land on reels one, three and five.

How keys change roles
Chest one offers prizes from 3x to 10x stake, chest two from 15x to 50x and chest three from 75x to 250x. Keys may carry multipliers of 2x, 3x, 5x, 10x or 20x, applied to the prize from the chest they open. If multiple multiplied keys open the same chest, their multipliers are added together. That rule is additive, not a chain of multiplications between keys.
Extra keys behave according to the current unlock state. Before chest two is open, extra keys open chest one. Once chest two is available, landing three keys opens both the first and second chests. Once all three are unlocked, each key opens the chest it corresponds to. The same symbol can therefore advance access or award a prize depending on progress. Counting keys alone does not reveal whether the spin is paying a chest or moving toward one.
Free Spins and temporary access
Three Free Spins scatters on reels two, three and four award ten spins. Three more during the feature add another ten. Dragon Keys have a higher chance of landing in Free Spins, improving opportunities to use the chest system without guaranteeing a key or any particular prize. The bonus retains the same dependence on which chests are unlocked and which one a key can open.
Feature Buy offers a Dragon Chest round for 20x stake, guaranteeing one or more keys and opening one chest. The Free Spins option costs 80x and guarantees entry; all chests become available during that bought round. After it ends, the game returns to the previous progress state. This temporary exception matters: the purchase exposes the higher tiers for the round without permanently removing locks from ongoing progress.
Configuration and limits
The detailed page lists 95.80% RTP, numeric volatility 16.45 and a 7,661x maximum payout. It released on 30 January 2025 and uses 5×4 reels with 40 lines. Evolution’s catalog lists 95.69% and 92.73% RTP configurations and labels volatility high, so the exact casino setting should be checked. The feature descriptions provide no trigger probabilities or quantified increase in key frequency during Free Spins.
The chest ladder has clearly stated milestones and prize bands, while the additive multiplier rule makes multi-key settlement understandable. Its limitation is state dependence: some keys unlock rather than pay, and the value of a key depends on which chest is available. Free Spins increase key likelihood without stating how much; bought access temporarily overrides progress and then reverts. Readers who enjoy tracking a persistent unlock system may find this satisfying, while those expecting every key to cash out immediately may not.
Strengths and weak points
Strengths
Three prize bands and explicit surplus-key behavior make progression understandable, while same-chest multipliers add under a clear rule rather than compounding unpredictably.
Weaknesses
Early keys may unlock rather than pay, trigger odds are absent, and purchased access to all chests ends when that round finishes.
Our Editor’s View
Dragons’ Lock is clearest when treated as a progression system: early keys open access, later keys can pay through increasingly valuable chests, and multipliers apply to the chest actually opened. The rules for surplus keys and additive multipliers help make the feature’s settlement legible. Free Spins raise the chance of keys, but do not specify a frequency or guarantee a result; bought all-chest access lasts only for its round. That distinction is central to judging the game. It should suit players who like tracking an unlock state, but may frustrate anyone who expects each key to deliver an immediate prize.
