LogiCue
Daily Machine
The machine hides a secret rule. Feed it numbers, watch what comes out, then prove you cracked it.
Machine log — 8 experiments left
No experiments yet. Feed the machine a number to see what it does.
LogiCue flips the usual daily-puzzle formula. Instead of guessing a hidden answer and getting hints, you run experiments: type any number from 0 to 999, feed it to the machine, and it prints what comes out. Every day the machine follows one secret rule — it might be adding something, juggling your number's digits, or measuring a property of the number itself.
You get eight experiments per day, but you don't have to use them all — the fewer you need, the better your result. When you think you've cracked the rule, hit the button and prove it: the machine gives you three new numbers it has never shown you, and you must predict all three outputs. Get every prediction right and the day is yours; miss one and the machine wins.
There's no dictionary to memorize and no trivia to know — just observation, hypothesis, and proof, the scientific method as a two-minute daily ritual. LogiCue is completely free — no sign-up, no downloads, and a fresh rule every day.
