Top Secret 1988

Each player is given a secret subject. Each subject has four clues, with each clue having a purchase price: $250, $500, $750, and $1,000.

One player is selected to read aloud a trivia question. The player who answers that question correctly receives a random reward between $200 and $1,000. A player must buy a clue from an opponent when afforded. Guessing an opponent's subject earns the guesser $500, with the other player eliminated from the game.

The process repeats until only one player remains, who then goes on to play the "Super Sleuth Round" where s/he must guess three secret subjects in under one minute for $5,000.

The player with the most money after two games is the winner.

This is a faithful adaptation of the 1988 CBS game show of the same name, although the show itself never actually got past the pilot stage. The board game was only released briefly before being pulled, mostly due to this but also because it shared its name with a TSR, Inc. RPG that was already on the market.
