Quicksand was a board game published in 1989 by Parker Brothers. It should not be confused with the 1981 game of the same name made by Whitman. Each player controls one of six explorers racing to discover an ancient temple.
The object of the game is to be the first player to get your adventurer around the board from START to the finish line back at CAMP.
The player pawns represent a mustachioed archetypical British explorer, and they're in parts. To represent your sinking into the quicksand, you remove his feet, then his waist, and so on until only the pith helmet remains.
You actually start already partially mired (by an initial die roll); every turn you move forward a number of spaces given by your height, plus an optional movement die. You can never sink more than hat-deep (so you cannot be eliminated).[1]
