Bidding on Star Wars
Logic-Grid
Logic Grid puzzles come with a handy interactive grid that will help you solve the puzzle based on the given clues.Logic-Grid
Five people were involved in an on-line auction for a photo of the original "Star Wars" crew. The bidding started at $200 and climbed. Each person was multitasking and doing something off-line while watching the bid (one of them was watching TV). From the clues below, determine the name of the person, their screen name, how much they bid, and what they were doing in the real world at the time.
1) The initial bid of $200 was made by the person who was reading at the same time, not by the bidder whose screen name was Ewok Master.
2) Neil raised it to $225, but he was not eating lunch; the bid by the person doing that was lower than Matt.
3) Blaklee didn't take the bid to $250.
4) The person whose screen name is R2D3 clicked at $275.
5) Jessica was vacuuming while registering her bid, but it was lower than that of the person whose screen name was Jedi13.
6) The bidder going by Force Knight was washing the car at the same time as the auction.
7) George's screen name is Lord Jabba.

I enjoyed it!
Is there a typo in Clue #5? "...vacuuming which registering..." Shouldn't it be, "...vacuuming while/when registering..."?
Typically tricky one from you. Can't believe I solved it the first time!

Good one
Took me two times to solve it. After marking the clues in the grid, I had to look at the obvious consequences. It took some time, but I figured it out! Great job!
