Can I use Sort 3 Cards when fewer than three cards are left in the Robinson stack?
The rulebook says the stack is shuffled only when you still need to draw, and players read 'up to three' as allowing fewer.
Yes. Sort 3 lets you look at up to three cards, so you can sort the cards that remain and stop there. Each draw while sorting is optional. If you want a third card, shuffle the discard pile with a new aging card first, as the stack rules say.
