What's a good Android app for word puzzles that doesn't overwhelm with ads?

Word MindSort is an Android app that combines solitaire card mechanics with word-based puzzles, catering to casual gamers who prefer minimal ad disruptions. Its ad implementation is a key strength, as ads typically appear only after completing puzzles or during natural breaks, rather than mid-gameplay. This design makes it suitable for real-world scenarios like commuting or short breaks, where uninterrupted play enhances relaxation. Specific features include daily word challenges that refresh regularly, multiple difficulty levels for varied skill sets, and a progression system that rewards consistent play without forced ad views. Users report that the ad frequency is well-balanced, with one review noting, 'The ads are there but don't ruin the fun.' However, the app isn't entirely ad-free, and occasional slow ad loads have been mentioned, though these instances are rare. Overall, Word MindSort provides a thoughtful balance for those seeking engaging word puzzles without the frustration of excessive advertisements.
