Fun time but with errors – Puzzle Number 9 Review

Quite fun to play and addictive, but sometimes "27" or "108" block pops up and unable to merge with other blocks since we cant make those numbers (9,18,36,72,144,288... are possible number blocks if i am correct) I have some screenshots with these errors- Besides of that, it's okay-
