The hammer is too slow to use against fast rumblers. For example, if a hammer is against a turbo-strike blackjack user, then the hammer user won't have a chance to add bruises into his strikes. This would cause the hammer to play horribly. It turns out the the risk/reward ratio is horrible on the hammer. You have to risk large amounts of loose blocks (the method that the bruises get added) getting messed up by opponent strikes, just to send a couple rows of bruises. --Boothook 20:38, 29 May 2006 (PDT)

The drop pattern for sprinkles has been changed. I'm afraid I don't know how to edit images, so someone else will have to upload the correct one. Specifically, the two rows have been swapped. Deathprog23 06:42, 30 August 2006 (PDT)

Details and a shot of the updated pattern are here for anyone that has the time to do this update. --Rixation(t/c) 07:28, 30 August 2006 (PDT)
The pattern for the Hammer has been corrected, but the description is inaccurate. Please supply a new description. Mcgarvery 23 October 2006
