Rularoo: Daily Logic Puzzle

Brain teaser & deduction game

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

You are shown three numbers. They follow a rule. Find it. Rularoo is a daily deduction game built on Peter Wason's 2-4-6 task, the experiment that showed people look for evidence that confirms them and almost never for evidence that would prove them wrong. Test any sequence and the game tells you whether it FITS the secret rule or FAILS it. When you think you have it, build the rule itself out of tokens. You get three commits and three hints. WHY IT IS HARDER THAN IT LOOKS The rule people reach for is almost always narrower than the real one. A narrower rule only accepts sequences the real rule also accepts, so every sequence you test to confirm your idea comes back FITS. Confirmation cannot get you out. The probe that frees you is one you expected to fail. THREE PUZZLES A DAY Easy: three terms, 1 to 30. A gentle vocabulary and a par of two to five probes. Medium: three terms, -20 to 99. Negative numbers, sums and gaps come into play. Hard: four terms and rules that combine two conditions. Par runs to twelve. JUDGED ON BEHAVIOUR, NOT WORDING Your rule is right if it accepts and rejects exactly what the secret rule does. "Every gap is positive" is accepted when the answer was "every term is greater than the one before it". They are the same rule. BEAT PAR Par is what a perfect player needs: at every step, the probe that splits the remaining possibilities most evenly. Finish under it and you outplayed the solver. RULAROO PRO Unlimited practice puzzles, the Coach (see how your line compared with the shortest one, and what everyone else guessed), streak insurance for one missed day a month, and the complete archive. Pro never buys extra commits or hints. Today's puzzle is the same for everyone. Free to play, in English and Spanish.
