Abstract: A system and method for pseudorandomly assigning a side to a gambler in event betting, such as sports betting. The system and method allow for a gambler to bet on past, present, future, electronic, or simulated events. When the gambler indicates the intention to accept a random assignment of a side, a wagering server pseudorandomly selects a side for the gambler. The system and method can be extended to contingent bets and batched betting.

Abstract: A new trivia-based card game comprising a deck of cards with a plurality of planar playing cards. Each planar playing card has three orthogonal pieces of information on its playing surface: an index, a card value, and a topic. Each planar playing card also has an answer value list and an answer list on its playing surface. The deck of cards may be sorted into unique sub-sets based off of index, card value, or topic. All of the planar playing cards contained in each sub-set sorted by topic share an answer value list and an answer list. A trivia-based card game can be played with such a deck.
