Drag the tiles to where you think they belong. When close enough, your tile should automatically snap to the grid slot when you let go.
I decided to experiment with the "distance to" block. There's another project I'm working on where I also primarily use this block. Sorry if this isn't a challenge, because I was mainly focusing on the mechanics of the project instead of the actual gameplay. Feel free to remix the project and modify it so that it's a bit more challenging.
