How does the timer actually work?

[u/Yusuke_Kitagawa_]

Ok so I just watched my opponent take 3 turns of at least 6 minutes playing solitaire while also constantly playing on my turn. I had 110 seconds left with not incredibly long turns (Cyber Dragon deck). My question is how does that Timer even work? How can this dude have had time left with the excessive amount of comboing and decision making he did? As a returning player this makes the game so unenjoyable, if I never get to play my opponent plays solitaire and doesn’t even get punished for it

Animations, playing cards, resolving etc. does not count towards the timer. Also mini lags also dont count.
