Rootclue

You have the outcome. Can you uncover the cause? Rootclue is a daily reasoning game that starts at the end. One coffee. Two receipts. Three people. No money changed hands. What happened? Instead of asking what comes next, every case asks you to work out what already happened. WORK THE CASE Read the outcome. Reveal evidence one card at a time. Mark what supports your theory, test an explanation against every clue, and call out the contradictions before you commit. Then see the accepted chain of events and why the alternatives fail. FOUR PUZZLE MODES • Outcome Selection: pick the explanation that fits all the evidence. • Missing Step: find the event that connects the chain. • Sequence Reconstruction: put events back in causal order. • Evidence Filter: sort relevant evidence from noise. A NEW CASE EVERY DAY One daily case chosen for your local date, usually two to seven minutes. Want more? Unlimited practice is always available. LEARN AS YOU GO A guided tutorial teaches evidence versus assumption, causal ordering and spotting contradictions. Practice levels run from Warm-up to Expert, and tiered hints nudge you forward without ever blocking completion. SCORING THAT REWARDS REASONING Rootclue scores how you think, not just what you pick: conclusion, evidence coverage, contradiction avoidance, sequence accuracy and revision efficiency. A small time bonus sits at the edge, not at the centre. CONFIDENCE CHECK Before you commit, say how sure you are, from Guessing to Certain. Rootclue tracks how well your confidence matches your accuracy, so your score reflects judgement as well as the answer. PROGRESS THAT STAYS WITH YOU Earn mastery stars and climb ranks from Observer to Master Reasoner. Track Journey Days, your Weekly Rhythm and a streak with a monthly grace day. Ranks never go down. BUILT FOR STOLEN MINUTES Made for the commute: one hand, no sound needed. Leave mid-case and the session picks up exactly where you left off. Share a spoiler-free result card when you finish. ACCESSIBLE Screen reader labels, font scaling, tap alternatives for every drag, colour-independent cues and reduced-motion support. No information depends on sound.
