I should have known that! - A Trivia Game About Things You Oughta Know, Green

The consensus

What reviewers found

Synthesized across the trust-weighted source mix below.

'I Should Have Known That!' is the trivia entry here, built around general-knowledge questions people feel they ought to know. Its strongest signal is scale and longevity: 4.5 across roughly 34,000 verified-purchase ratings, the largest sample in this pool, which points to durable appeal as a casual trivia filler for mixed groups. The only signals supplied for this candidate are those customer ratings—no independent expert testing or specialist-community threads were attached—so we treat the high volume as a satisfaction indicator rather than a measured verdict.

What reviewers liked

  • Largest verified-purchase sample in the pool (~34,000 ratings)
  • Affordable, simple trivia format good as a casual filler
  • Broad general-knowledge questions suit mixed adult groups

Where it falls short

  • No expert or specialist-community signals supplied
  • Slightly lower average (4.5) than the word and deduction staples
  • Trivia formats can frustrate players with knowledge gaps and feel repetitive over time

'I Should Have Known That!' is the trivia entry here, built around general-knowledge questions people feel they ought to know. Its strongest signal is scale and longevity: 4.5 across roughly 34,000 verified-purchase ratings, the largest sample in this pool, which points to durable appeal as a casual trivia filler for mixed groups.

The only signals supplied for this candidate are those customer ratings—no independent expert testing or specialist-community threads were attached—so we treat the high volume as a satisfaction indicator rather than a measured verdict. The slightly lower average than the word-and-deduction staples is worth noting; trivia games tend to draw more polarized reactions depending on how fair players find the questions and whether knowledge gaps frustrate or amuse the table. For groups that enjoy trivia banter, it's a low-cost, reliable option.
