I Play Therefore I am!

Ergo is the logical card game for the geek in all of us. Each player plays a variable (A, B, C, or D) and uses familiar logical operators like 'Not', 'And', 'Or', 'If-Then' to prove they exist, and that their opponents don't!

Along the way, watch out for cards that will shift the equation like Wild Cards, 'Tabula Rosa' or the dreaded 'Fallacy' card.

Each Player takes turns creating and changing the four premises of the proof to make 'true' statements. Watch out though, when someone plays the Ergo card, whoever is true scores!
