An article on Tuesday, March 30, about the Penny Arcade Exposition misrepresented an event involving a microprocessor. Jerry Holkins (aka Tycho) offered an Intel Core i7 processor to a fan who represented a community that had presented the comic creators with PAX-themed trading cards. That fan donated the processor to Penny Arcade’s charity, Child’s Play on behalf of the community. The processor was not declined by the fan, nor was it offered in return for the cards.

Tuesday’s issue inadvertently presented only the upper-left corner of the Sudoku solution. Tuesday’s Sudoku solution is reprinted in this issue on page 25.
