Leaving holes (nothing) in your lines will GO WRONG.

Sereiously. Don't leave holes. They cause ChAOs.

cHaOs makes everything much much HARDER. AND THINGS THEN GO WRONG.

Occasionally you get golden pieces. USE THEM WISELY because

Gold pieces can pass through blocks and replace them! and also they can fly! Use W (UP) to make them fly! lock them with [SPACE] anywhere.

Gold blocks can help you fill holes, but they are rare so careful!

Try filling holes and clearing lines to decrease chA0s and make the game easier.
