I can tell you that this is probably the favourite machine I have in my collection. Once you get through your missions and on the way you light up the BLASTOFF letters you are ready for the 13 balls to come at you after countdown. Also along the way you can also get a 3 multiball as well which keeps the interst level up. Overall in my opinion it is not an easy game to play as it has very narrow lanes so the difficulty factor is higher but isn't that part of the overall fun? "Thirteen it's Houston"
