return tiles.indexOf(tile) != -1;

Java Web Development Techdegree Graduate 21,083 Points'tiles.indexOf(tile) != -1' is a boolean expression. It can only have two values: it's either true of false. So with your if block you're saying: if it's true return true, else return false. It's redundant. just return the boolean expression directly, it already has the value you need to return.
