Ok I don't think I get the rules of tetris.
I've done a big chunk of the Marsh, I'm in one of the basements doing puzzles with the blue outline blocks. Do these have to cancel a yellow block or can you have them on their own? I'm on one puzzle where the grid is 4x4 and I've only two yellow blocks in it and everything is quite spread out, not seeing how I can group things.
You must use up all the blue outline blocks to cancel out yellow blocks. They're invalid on their own.
