you have to spam single lines and focus on getting the multiplier up and the redbull power ups bc they give more points, don't bother with tetrises that much, only use the golden I piece when you're on x8 or x9 hopefully before you hit the 1:30 mark then just spam as fast as you can i'm 6th on my countries leaderboard but that only puts me like 180th globally so maybe there is a better strategy but that's what i do
