How to read a room before you drop a piece
Fill the Space asks one thing of you each day: fill four rooms using every piece in the tray, with as few extra drops as you can. These guides show how to read a room before you touch it, so your drops go where they can stay. Each one is built on real rooms from past days, so you can open the day in the archive and try it yourself.
