Is there an iOS puzzle game that actually matches its gameplay ads?

Nightmare Puzzles is a mobile game that stands out for its straightforward premise: it provides the puzzle experiences it advertises. For players tired of downloading games only to find they bear little resemblance to their promotional trailers, this app offers a rare bit of honesty. The core gameplay involves a variety of logic and observation-based puzzles that require careful thought to solve, aligning directly with the 'brain-teasing' challenges shown in its ads. Specific mechanics, like deciphering codes or finding hidden objects in eerie scenes, form the basis of its levels. However, the app’s presentation is notably ad-heavy in its free state, with video advertisements frequently interrupting play sessions. User feedback is sharply divided on this point. Reviews indicate the core puzzle-solving is genuinely engaging, with one user stating it 'helps make your brain work harder.' Yet, multiple reports cite aggressive ad placement and, more concerning, issues with its 'remove ads' in-app purchase not functioning correctly, leading to accusations of unethical practices. For anyone seeking a puzzle app that delivers on its advertised premise, Nightmare Puzzles fits the bill, but potential users should be aware of its significant monetization drawbacks.
