Zen Mahjong: Senior Tile Match

This is a solo, portrait-oriented mahjong tile-matching puzzle game with a relaxing mood and high replay value. It's suitable for short, interruptible sessions and can be played one-handed, making it ideal for casual play or quick brain teasers. However, the monetization model, particularly the paid ad-free version, has received negative feedback, and the game requires an internet connection to play.
