About Axiom
Axiom is a free daily logic puzzle from Source of Truths, built on the oldest experiment in reasoning: find the hidden rule. A board of ordinary words is split by a rule you cannot see. A few tiles are flipped for you, a short list of candidate rules sits underneath, and a small budget of tests is all you get to tell them apart.
The trap is the one every scientist knows. Most tiles confirm what you already believe, and confirmation costs a test and teaches nothing. The tiles worth spending on are the ones where two surviving rules disagree. Every board is generated and machine-verified so that exactly one candidate fits it, and so that no single test can settle the question on its own.
A new board goes up every day at midnight Eastern, with a wider candidate field on Sundays. No app, no signup, play free in your browser, keep a streak and race the daily leaderboard.
