## What is Total Synthesis?

A complete organic chemistry study app with a full roguelike deckbuilder living in its basement. 
Drill every topic, push every mechanism's arrows yourself — then descend into a lab gone wrong, where the same chemistry keeps you alive.

STUDY — EVERYTHING BEFORE THE EXAM (AND AFTER)

• 1,000+ Practice Items: ~20 drill formats across every topic — formal charge, stereochemistry, spectra, synthesis, and more. 
Built for semester exams, MCAT review, post-bacc and continuing education.
• Push the Arrows: Every mechanism, step by step — watch each move explained, then draw the electron-pushing arrows yourself and get graded
on them. Stuck? Hints and a worked solution are one tap away.
• Full Mock Exams: Build a practice test with pace presets and exam-style deferred feedback, the way the real thing scores.
• Flashcards & References: 28 decks with spaced review, authored lessons per topic, and the complete reaction library — a quick reference that
stays useful on the job long after the exam.

PLAY — THE BONUS: A REAL ROGUELIKE DECKBUILDER

• Contain the Outbreak: Something got loose in the university's chemistry building. 
Descend the sublevels, requisition your deck from the stockroom, and seal the source.
• The Chemistry Is the Combat: Reagents are cards. Match nucleophiles to electrophiles, chain mechanisms for payoff turns, and mind the thermometer and the pH meter — the conditions punish greed.
• An Ever-Changing Lab: Every expedition redraws the containment map — different rooms, specimens, caches, and bosses. Every fight quizzes the same chemistry you study.

Free to try. One purchase unlocks everything — no subscriptions, no microtransactions.

### 5/5 — Finally a decent ochem app

*2026-08-26*

The arrow pushing drills are exactly what I was looking for to help me last semester, definitely using this for ochem 2. I really like the mechanism trainer too, goes in depth on each step and is super helpful. Highly recommend.

### 5/5 — Really fun game

★★★★★

Such a fun way to study organic chemistry. Really enjoyed the games within it! hopefully this helps me this upcoming year!!

  tiny in a corner, and their highlight overlays no longer balloon.
• Fixed a status label ("STAGGERED") that wrapped its last letter onto a
  second line.
• Self-targeting reagents now aim at your chemist automatically.
• Choosing a room on the expedition map now plays a brief lock-on
  confirmation before you enter.
• Card faces are easier to read at a glance.
• Fixed pop-up panels that cut their contents off instead of scrolling once
  a list got long.
• Fixed some UI issues with the 4:3 iPad screens.
