Tetris

This trophy gave me trouble at first but then I figured out a way to make this a lot easier. You will need your partner to go as slow as possible and spread blocks out and even clear single lines if they want while you prepare for this. You will of course need to have 12 lines lined up ready to be cleared with a straight block on hold. Now you can wait for that magic moment when you have a straight block on hold and two of them come one right after another or do what I did and told my friend to do and it worked great. You have one on hold and then one will come into your queue. You need to drop the one from queue into place, swap out drop the other into place, then SPAM up to drop blocks into place and hopefully a straight block comes into queue and drop that into place. It might take a few tries but after we started using this strategy it didn't take long. You can throw down a good amount of blocks in 5 seconds while going for your last straight block. Once you have done it 12 lines will appear on your friends screen and the trophy will pop.
