What's the best Android app for solving mystery puzzles without energy timers or paywalls?

Hidden Escape Mysteries is an Android game that caters to players seeking immersive puzzle-solving without the constraints of energy meters or aggressive monetization. Developed by Supercharge Mobile, it features a collection of story-based hidden object scenarios across multiple series, allowing users to progress through chapters at their own pace. Key attractions include the absence of pay-to-advance mechanics, which reviews highlight as a major plus, enabling extended play sessions without interruption. Mini mysteries offer optional tasks to earn extra stars, adding variety and replay value. The ad-supported model is reported to be minimally intrusive, supporting development without disrupting the experience. However, some technical flaws exist, such as a noted bug in the circus mini mystery where medals may not register correctly, though these instances appear sporadic. With a 4.5-star rating, the app balances depth and accessibility, making it suitable for casual gamers or those diving into longer detective narratives. Its content-rich design, including numerous chapters and series, ensures sustained engagement, though occasional updates might be needed to polish minor issues. For anyone prioritizing freedom and story in puzzle games, Hidden Escape Mysteries stands out as a dependable choice.
