One round, every penalty
The Complex round uses the same values as standard Trix and applies them simultaneously: King of Hearts −75, each Queen −25, each Diamond −15, each Collections trick −10. A single bad trick can cost you on more than one count, which is the whole point of the variant.
Doubling works as it does in standard Trix and applies to the King and the Queens within the Complex round — the eater pays double, the doubler collects the face value for feeding it away.
