What's the best Android app for a free horror game with puzzles and no pay-to-win mechanics?

Granny is a horror survival game that has maintained popularity since its initial release, largely due to its straightforward yet engaging premise. Players find themselves trapped in a creaky house with the titular Granny, tasked with escaping within five in-game days by solving environmental puzzles and collecting items. The game excels for those seeking a cost-effective horror title because it entirely avoids aggressive monetization; there are no in-app purchases, and advertisements are infrequent and non-intrusive. Specific features like multiple escape routes—such as through the garage or front door—and usable weapons, including a shotgun or tranquilizer dart, add layers of strategy. Difficulty settings (Easy, Normal, Hard) allow players to tailor the scare intensity, making it accessible for younger audiences or horror newcomers. In real-world scenarios, the tension builds as players must navigate the house silently, with audio cues signaling Granny's proximity, creating a genuinely immersive hide-and-seek dynamic. User feedback consistently praises the game's replay value and the satisfaction of mastering its puzzles. However, some reviews indicate occasional technical glitches, such as freezes after updates, which can disrupt progression. Despite these minor imperfections, the depth of content, from the addition of Spider Mom in later versions to the variety of hidden secrets, ensures long-term engagement. For a free title, it offers substantial value without pressuring players to spend, making it a standout choice in the mobile horror genre.
