About Tech Exchange, from BoardGameGeek:
Tech Exchange is a multi-player, real-time trading card game for 2-6 Players. It uses a modern deck of cards called the Tech Deck. Each card in the Tech Deck represents stocks in companies that players trade. As players trade cards and use card abilities, the stock market gains value. Each stock card has card abilities that players can use during two turn-based effects rounds. Players score victory points based on the value of their final hand after all trading is completed. Players are trying to collect sets of triples, quadruples and a flush (cards that share a domain/suit).
REAL TIME TRADING – The players trade cards from their hands between each other in real-time. There are no turns and trading happens simultaneously between players following a few trading rules.
USE CARD EFFECTS – When a stock stack hits a value of three or no one wishes to trade anymore, trading pauses. Then, players take turns using effects on the cards in their hand. Trading continues. After all trading has completed, there is a second use effects round.
STOCK SCORING – After the second use card effects round, players tally up victory points based on the value of card groupings in their hand and the value of the stock market.
WINNER – After three rounds of play, the player with the most points is the winner. If tied, players share the victory.
TECH DECK AS A GAME SYSTEM - The Tech Deck is a modernized deck of cards bringing playing cards into the 21st century. It is a game platform designed to support many different games. Each card in the Tech Deck has unique game effects to create unique game experiences. Also, see Tech Grid Poker, Tech City which are other games that use the Tech Deck.
