Do they contain bleach?

They work by giving a very faint blue tinge to your wash, which removes the yellowish tint that a white wash can sometimes get. Having said this, I don't know if they do contain bleach, but they don't have a bleaching effect, anyway. As they do tint washing blue, they should be used only in very small quantities, I find less than a quarter of one block is enough for an average wash.
