Format and gameplay
The core loop is almost identical. You get one case a day, commit to a diagnosis, and each wrong guess reveals the next clue, with fewer guesses being a better result, and a grid to share at the end. iatroX Rounds allows up to six guesses; Doctordle uses a slightly shorter run. In practice the feel is very similar, which is a credit to the format Doctordle helped popularise.
UK versus US context
This is the real differentiator. Doctordle is framed around US exams and US clinical norms. iatroX Rounds uses UK clinical context throughout, including UK drug names and NHS framing, and aligns to UK exams. For a UK student or doctor, that means the cases and reasoning match what you will actually be tested on, which is the main reason to prefer it.
Free access and accounts
Both are free and playable without an account, which lowers the barrier to a daily habit. In each case, creating a free account saves your streak and stats across devices. Neither hides the core game behind a paywall.
Exam relevance and the wider ecosystem
If you are revising for UK exams, iatroX Rounds has two advantages: its cases are built in a UK context, and it sits alongside the iatroX question bank and Academy, so a daily case can lead naturally into structured practice. Doctordle's strength here is its Anki export, which suits people who already run a spaced-repetition deck, and its large community.
Which suits you?
- Choose iatroX Rounds if you train in the UK, are preparing for UKMLA, PLAB, MRCP or MRCGP, and want your daily case in a UK context with a path into fuller revision.
- Choose Doctordle if your focus is US exams, or you want an established game with an Anki export and a big community.
