Decoction
iOS Universel / Jeux
Cure the cough. Don't poison the squire.
Decoction is a historical-fiction roguelike deck-builder set inside a 1690s European apothecary shop. Patients arrive at your door with ailments described in period language. You diagnose the humoral imbalance, draw a hand of ingredient cards, and combine them in the mortar to formulate a remedy. Each card is a real plant, mineral, or animal product drawn from Nicholas Culpeper's Complete Herbal (1652) and the London pharmacopoeia of the period, with its hot, cold, dry, or moist signature and its classical planetary rulership preserved.
Decoction is a historical fiction game inspired by 17th-century pharmacopoeia. Nothing herein is medical advice. Do not treat real illness with herbal remedies. Consult a licensed physician for any health concern.
WHAT'S IN THE BOX
- 150 ingredient cards, hand-authored from Culpeper sources. Herbs, minerals, animal products, spirits, syrups, powders, and pre-prepared decoctions, each with its own humoral signature, planetary rulership, and attribution quote.
- 60 hand-authored patient cases. Villagers, townsmen, gentry, and grandees. Phlegmatic catarrhs. Sanguine fevers. Choleric biles. Saturnine melancholies.
- A diagnose-and-formulate puzzle loop. Read the symptoms, choose a humour, draw five cards, play two to four, score the cure.
- A seven-day campaign tour through villages with persistent reputation and gold. Three grievous failures and the constable invites you to leave town. Eighty percent cures and you triumph.
- A 25-achievement board covering every planetary rulership, every difficulty band, and a Compleat Cabinet for unlocking the materia medica.
- Period instruments soundtrack rendered procedurally on device. Lute, recorder, and viola da gamba in Dorian and Mixolydian modes. No samples shipped.

THE FRAME
Decoction preserves period language because the puzzle is built on the texts of the period. We have kept the original attributions and astrological notes from Culpeper. None of it is medical advice. Several historical remedies were ineffective and some were actively harmful. Saying so is part of why evidence-based medicine exists and part of why this is a game, not a pharmacy.
If you are unwell, please consult a licensed clinician.
Quoi de neuf dans la dernière version ?
Decoction 1.4 - Daily Challenge and Mortar Sandbox:
- Daily Challenge: every calendar day the same patient arrives for every player, with the same hand of five cards - no network needed, the puzzle is seeded from today's date. One attempt per day. Complete it to earn a streak; share your result (outcome + score, no spoilers) with a tap. Streaks tracked on-device.
- Mortar Sandbox (Pro Almanac): a risk-free practice room. Pick any humoral target, browse all 150 catalog ingredients sorted by corrective distance, select two to four, and score the result. The sheet shows a full signature comparison, the Culpeper note for each card you used, and a Try Again button. No run, no stakes, no limits.
- Apothecary Forecast expanded: the main-menu forecast now cycles through seven distinct planetary-day entries (one for each day of the week) instead of three, so the card shows something genuinely different every day of the week.
- No new permissions, no network calls, no tracking. All data remains on your device.
