What’s the Hardest Level in Kris Mahjong Levels?

[metol]

Hi everyone,

I’m currently progressing through kris mahjong levels and noticed that some stages get really tricky with the time limit. Does anyone know which level is considered the hardest? Also, is there a way to replay specific levels to practice and improve your score? I’d love to hear how others approach the tougher challenges in this game.
