Had a great time playing around 600 games

It's a very smooth and well-made game among Shanghai-style games, which gave me the motivation to keep playing regardless of rewards. I played about 600 games, got 1st place every day, and reached the highest league tier... However, suddenly in a stage with keys and locks, all the key tiles were below the lock tiles. I've used shuffle items a lot before, and usually, using just one per game was enough to clear it, but even after using shuffle 3 times, the key tiles were still only below the lock tiles. Seeing this felt unfair, so I deleted the game. Nevertheless, I recommend it if you enjoy Shanghai-style games.
