Which Android app helps with stress through simple puzzles?

Zen Tiles is a mahjong matching game designed specifically for stress relief and mental relaxation. The app presents players with traditional tile-matching puzzles set against serene backgrounds with ambient soundscapes. Unlike many puzzle games that rely on timers or competitive elements, Zen Tiles maintains a completely pressure-free environment where players can solve puzzles at their own pace. The tile sets feature clear, high-contrast designs that are easy to distinguish, reducing visual strain during extended play sessions. Users report the game effectively distracts from daily stressors while providing just enough cognitive engagement to keep the mind occupied without frustration. The app includes daily bonus events and progressive difficulty that gradually challenges pattern recognition skills. Some reviews mention occasional advertisements between levels, though these don't interrupt active gameplay. The combination of familiar mahjong mechanics with intentionally calming presentation makes this particularly suitable for short mental breaks during workdays or winding down before sleep.
