Daily medical minigames

A new case every day. Four ways to crack it.

Stat! turns clinical reasoning into quick daily puzzles. Work up a presentation, narrow a diagnosis trait by trait, find the four findings that belong together, and home in on the hidden structure.

Free on iPhone and iPad. Plays in any browser. Android soon.

The games

Four games. Four kinds of clinical thinking.

Each one trains a different move: the workup, the deduction, the association, the anatomy. Every game gets a fresh daily puzzle, a timer, and a result you can share.

01 · Workup

Work up the case.

A presentation and a patient. Ask about symptoms, check vitals, order labs and imaging, and every answer lands in the chart as a finding. Name the diagnosis before your tries run out.

  • 6 diagnosis tries
  • 2 chart hints
  • 4 investigation tabs

02 · Deduction

Narrow it down, trait by trait.

Guess a disease and six traits light up: system, type, acuity, organs, how it is diagnosed, how it is treated. Green is exact, amber is partial, grey is a miss. Close in.

  • 6 traits per guess
  • 15 guesses
  • 2 hints
How to play Traits

03 · Association

Find the four that belong together.

Sixteen findings, four diseases. Pick the four that share a diagnosis and submit. A near miss tells you you are one away. Each group you solve reveals the disease behind it.

  • 16 findings
  • 4 groups of 4
  • 12 tries
How to play Associations

04 · Anatomy

Home in on the hidden structure.

One organ, bone, muscle, vessel or nerve is the target. Each guess is plotted on the body and scored by how close it sits, so every miss narrows the map.

  • 349 structures
  • 3 tiers
  • 10 guesses

Learn

The medicine behind the games.

Plain-language guides to the reasoning, tests and anatomy the puzzles are built on, and a full how-to-play guide for every game.

Clinical reasoning

The clinical workup: from first complaint to diagnosis

How clinicians turn a presenting complaint into a diagnosis, with a focused history, a targeted examination and tests chosen to answer a question rather than to fish for one.

Labs, vitals and imaging

Reading lab results: what high, low and abnormal really mean

Where reference ranges come from, why one in twenty healthy people falls outside each of them, and how to read the common blood tests that show up in clinical cases.

Clinical reasoning

Classic clinical associations: findings that point to one disease

Some findings travel together so reliably that they suggest a diagnosis almost on sight. A tour of the classic pairings, and the traps where one finding fits several diseases.

Inside Stat!

How a daily puzzle is built: the library, the draw and the fairness rules

Where Stat!'s puzzles come from: a curated library of 250 diseases and 349 structures, one shared draw per date, and the rules that keep each game fair.

7 min read

Labs, vitals and imaging

Vital signs: the five numbers that frame every case

Temperature, heart rate, blood pressure, breathing rate and oxygen saturation, with normal adult values, the patterns that matter, and why a trend beats a single reading.

5 min read

Labs, vitals and imaging

Imaging basics: X-ray, ultrasound, CT and MRI

What each imaging test is good at, what it costs in time and radiation, and how clinicians choose the right one for the question they are asking.

Every day

The same case for everyone. New at midnight.

Every daily puzzle is shared by every player (Tangent has three a day, one per tier), so a streak means something and a share card is a fair comparison. Missed one? The archive keeps them all.

Today's menu

Four cards, one status each.

Solved, missed, or resume where you left off. The streak and the stats are one tap away.

Keep the streak. Watch the distribution.

Every game keeps its own record: plays, solves, average time, and how many tries each solve took.

Every past case, on the calendar.

The archive holds every daily puzzle since launch. Free in the browser, and part of Pro in the app.

● solved   ● missed   ● open

Share the result, never the answer.

The share card is time, tries and hints. Your friends still get a fair go at the same case.

A nudge at your hour.

An optional daily reminder, at whatever time fits between rounds and lectures.

Dark mode, of course.

Follows your system, or set it yourself. Every board, sheet and card has a night version.

Pick up where you left off.

Close the app mid-case and it is waiting when you come back, timer and all.
