When you receive a SPAM damage card, place it into your discard pile on your player mat. When you shuffle your discard pile to make a new programming deck, the SPAM cards will be in it. When you draw SPAM, it will build up in your hand over time as you DO NOT discard them at the end of the Programming Phase. To get rid of SPAM cards, you must program them into your registers or Shutdown your robot. When you reveal a SPAM card in one of your registers during the Activation Phase, you must take the following steps:
1. Immediately discard the SPAM card face up into the damage discard pile (next to the damage deck). Now it is out of your deck. This is the advantage of programming a SPAM card.
2. Take the top card from your programming deck and place it face up in your current register. It will be a random card, so it might really mess up your plans! And that is the disadvantage of programming a SPAM card.
3. Finally, resolve the new card that you placed in the current register slot. If that card is also SPAM, return to Step 1 above (and congrats on getting rid of 2 SPAM for the price of 1!).
