Let $X$ be a surface, possibly with boundary. Suppose it has infinite genusor infinitely many punctures, or a closed subset which is a disk with a Cantorset removed from its interior. For example, $X$ could be any surface ofinfinite type with only finitely many boundary components. We prove that themapping class group of $X$ does not satisfy the Tits Alternative. That is,Map$(X)$ contains a finitely generated subgroup that is not virtually solvableand contains no nonabelian free group.

Most big mapping class groups fail the Tits Alternative
