Overview

This is the definitive 1970s logic game that challenged millions to 'break the hidden code' using colored plastic pegs.

Story

Mordecai Meirowitz, an Israeli postmaster and telecommunications expert, invented this game after being rejected by several major toy companies who dismissed the concept as too simple.

Maker / Origin

Invicta Plastics was a small British firm specializing in industrial plastics before Mastermind catapulted them to international fame.

Condition & Value

The box shows significant shelf wear, including corner scuffing and a prominent horizontal crease across the center of the image. These signs of 'love' and frequent play are typical for family games, though they do keep the value at a modest level compared to a mint-condition example.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

  • Strong maker attribution with credible period details
  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
  • Surface wear or missing provenance can compress the range fast
  • Regional sale lanes often underperform specialist venues

Best Venue

Specialty auction or a focused dealer with buyers already in this lane.
