In Defense Derby, the user holding the most chips becomes the 'Chip Leader', and the units in the 'Chip Leader's' deck appear in the auction.
If you don't become the 'Chip Leader', units from your deck may not appear.
Chips can be earned in varying amounts depending on the bid amount at the auction, and also by selling units.
If you don't like the units appearing in the auction, you can strategically bid second highest to gain more chips than other players without acquiring a unit, preparing for the next auction.
Additionally, by selling units just before an auction to become the 'Chip Leader', you can make units from your deck appear in the auction.
Please enjoy Defense Derby by strategically using these rules.
