Huh! Interesting!! A simple math deduction will tell you that you can guarantee (with 100% certainty) that you will win this round (well, rather, HAL will win, but that means that you (as a team) win).
Can you choose what to play to guarantee that HAL arrives? (try to do it before clicking on Next)
Hint: How many 6's
are out there? Who has or have them?
