Double Blind - Designed by Bruce Glassco

A free board game from the 2005 Deduction Game Design Competition

By Erik Arneson, About.com Guide

For 2 players

INTRODUCTION

Each player draws a hidden victory condition. They then alternate placing tokens until one player has fulfilled BOTH conditions.

EQUIPMENT

  • Board with small squares (e.g. Go or Pente)

  • Colored stones for each player (e.g. Go or Pente)

  • Note: Graph paper and pencil may be used instead of the above components.

  • A set of cards labeled 1 to 5.

SETUP

Each player draws one card. Then consult the diagram below to see what your victory condition will be.

See Diagram: Possible Victory Conditions

GAMEPLAY

Choose a player to go first.

Players alternate placing pieces on intersections of the board, as in Go or Pente.

Whenever a player fulfills any of the five victory conditions, he must announce this to opponent. (It may be helpful to give each player a different suit of cards labeled 1 to 5. Then, each player may display cards to show which victory conditions have been completed.)

It is possible to complete more than one condition on the same move, or to complete condition 4 or 5 on your opponent's turn.

There is no benefit to completing the same victory condition more than once.

When a player completes his or her second different victory condition, she may ask her opponent, "Have I fulfilled your victory condition yet?" The opponent must truthfully answer yes or no.

A player may ask this question again whenever he completes another new victory condition.

WINNING

If your opponent has answered "yes" after being queried about his or her victory condition, and you have completed your own victory condition as well, then you have won.
