How so you kill the spider in level 270?

It bothers me that you offer a solution via someone else's gameplay that involves the purchasing of special game support items. Games should be play-able without having to make a purchase, even if it takes the player a while to complete the level. I have been on this level for months. I generally broke down and bought some aides to assist in getting by the level, to no avail! As its not the first time it has happened, it seems as if having to buy multiple support moves is built into some levels! Shame on you King.com!  You want to support the player? Then provide help that doesn't involve the repeated purchase of game support items!
