Does hiding the next block give you more points?

it determines letter grades. If you finish fast enough, you unlock the invisible credits roll. If you survive that with enough lines cleared, you'll get the highest rank possible, and a couple of lesser (but still incredibly impressive) letter grades are awarded if you clear too slow or can't survive till the end

If you don't finish all 999 levels fast enough, you have the semi invisible credits roll, which will award some lesser letter grades

Tetris Grandmaster games don't rely on points, they judge based on speed, lines cleared, and number of times you've tetris'd
