What's the best iOS app for a quick, brain-teasing puzzle you can play in a 5-minute break?

DOP is an ideal choice for filling short, idle moments with a light mental challenge. The core mechanic is straightforward: a whimsical, incomplete illustration is presented, and the player must draw the single missing component. This could be anything from a missing wheel on a car to a character's hat. This immediate, intuitive interaction means no complex tutorials are required, allowing players to jump directly into a puzzle within seconds of opening the app. The puzzles themselves are clever and often humorous, offering a genuine 'aha' moment when the correct part is identified and drawn. This makes it excellent for a coffee break, waiting in line, or any brief period where a more involved game would be impractical.

However, the primary limitation for this use case is the ad frequency. As one user review notes, 'you spend more time watching ads than playing.' Advertisements can appear after just two or three puzzles, which can disrupt the intended quick-session flow. While the free-to-play model necessitates ads, their density might lead some users to put the app down if their short break is consumed by a commercial. Despite this, the fundamental puzzle design is engaging and well-suited for short bursts. The app’s library contains hundreds of levels, ensuring variety and preventing immediate repetition during brief daily play sessions.
