Diagnostic Dice

Roll first. Ask questions later.

Tired of expensive OBD-II scanners, cryptic fault codes, and mechanics who "need to run more tests"? Meet the Diagnostic Dice — the only car-repair tool powered entirely by chance and a healthy dose of audacity. Simply roll the dice on your workbench (or hood, or dashboard — we don't judge) and let fate tell you what's wrong with your vehicle. From "Replace Gas Cap" to "Jiggle It," these dice cut through the noise and deliver a diagnosis faster than any scan tool on the market. Is it accurate? Statistically, about as often as that check-engine light means something serious. But it's a whole lot more fun — and you'll never need a firmware update.

"Rolled 'Replace Gas Cap' and my check-engine light actually turned off. I've never been more terrified of a product working."

"I replaced my $4,000 scan tool with these dice. My shop's diagnostic accuracy went up. I don't want to talk about it."

"Dice said 'Jiggle It.' I jiggled the battery cable. Car started. Coincidence? Probably. But I'm a believer now."
