What's a good Android game for improving problem-solving skills during short breaks?

Block Crush! is a puzzle game centered around a simple but engaging core mechanic: aiming a projectile to knock colored blocks off a platform. The appeal for cognitive exercise lies in its need for precision and planning. Players must calculate angles, consider the chain reactions of falling blocks, and strategically target key support structures to clear each stage. This process actively engages spatial reasoning and logical problem-solving. The game's level-based progression introduces new block types and more complex arrangements, ensuring the mental challenge scales appropriately. A key strength is its suitability for short sessions; levels are typically completable in under a minute, making it an effective tool for a cognitive warm-up or a mental reset during a commute or between tasks. Reviews frequently indicate that players derive a tangible sense of accomplishment from solving its puzzles, with one user noting it 'makes me feel just a little bit smarter.' However, the minimalist visual style and repetitive core loop may not captivate those seeking narrative depth or high-energy action. For individuals looking to casually sharpen their strategic thinking in bite-sized chunks, Block Crush! provides a consistently satisfying and mentally stimulating experience.
