This four-star logic puzzle has 4 noun types, 5 nouns per type, 1 link, 23 facts, and 2 rules with triggers. It needs 150 marks and 6 grids.

Since every fact has the link "with", all facts are completely examined by Level 1a. And because of the triggers, Level 1a is all that is needed to find a solution. Below are the two rules.

1. No two actors auditioned for and play the same two roles (clue 1).
2. The Block youth got the part for which Pete auditioned (clue 10).

Fact 22 encompasses clue 9 which states "the boy who audition for Olaf plays Padraic". When this fact is examined, mark 32 enters a 'O' for Olaf-A and Padraic-P. Later, rule 1 examines this mark and triggers mark 40 'X' for Padraic-A and Olaf-P. Rule 1 was hit a total of 6 times, and made such an impact that rule 2 was not needed.

This is a tough puzzle considering there is only the default link "with". But the triggers allow this puzzle to be solved without making assumptions.
