What's a good Android game for when I want to engage in a bit of linguistic pattern recognition, something that's almost meditative?

I recently came across 'Word Jam - Association Puzzle', and it's been a pleasant surprise. The algorithm is surprisingly elegant, presenting word associations in a way that's both challenging and calming. It's a novel approach to an old problem, and I appreciate the well-researched design. I find it intellectually satisfying to identify the connections between words, almost like a mini-research project each time. The cross-platform compatibility is also a plus, as I can pick up where I left off on different devices. This would be pedagogically sound for vocabulary expansion, too. It's a nice way to unwind after a long day of research, and the rating of 4.7/5 suggests others agree.
