OpenEvidence Synapses and iatroX clinical connections both offer a reason to look for relationships in medical information. They should now be compared as puzzle options, rather than comparing an OpenEvidence game with iatroX's question bank alone.
For someone seeking a free browser-based grouping challenge with published rules and an explanation after the reveal, clinical connections is a direct starting point. For an eligible clinician already using OpenEvidence, Synapses offers a puzzle within its Discover experience.
This comparison is published by iatroX and was updated on 18 October 2026. It uses public descriptions and the iatroX launch specification, not a controlled accuracy study or a completed logged-in test of every OpenEvidence feature. Details that could not be verified are identified rather than filled in from another similarly named game.
What OpenEvidence has publicly described
OpenEvidence's 10 August 2026 games announcement introduced two daily activities in Discover on the web and in its app.
MedMini was described as a miniature medical crossword. Synapses was described as a tile-based puzzle connecting diagnostic clues. These are different activities within the same collection, not two names for one format.
The announcement establishes the daily puzzle and its placement. It does not provide enough detail to independently verify every current scoring rule, error allowance, hint policy, archive condition or post-puzzle feedback feature.
It would therefore be misleading to import a sixteen-tile rule, a particular timer or another product's scoring system merely because the games appear related. A name or visual resemblance is not a complete specification.
What clinical connections asks you to do
A clinical connections board contains sixteen concepts arranged into four groups of four. Select four terms and submit the proposed group. A successful submission reveals its label, and the final remaining group completes by elimination.
The initial collection focuses on general clinical science, including anatomical, physiological and pharmacological relationships. That scope differs from a guarantee that every day's puzzle concerns a named specialty or examination.
Group explanations and supporting references follow the reveal. A separate optional application question asks the player to do something with an idea beyond identifying its category.
The activity is a complete free game. Related question-bank practice can provide a further route where suitable edition and library mappings exist, but it is not necessary to finish the puzzle or understand its explanation.
Compare confirmed features, not assumed absences
| Question | OpenEvidence Synapses | iatroX clinical connections |
|---|---|---|
| What is the documented task? | A tile-based puzzle linking diagnostic clues | Sixteen concepts organised into four groups of four |
| Is a daily edition described? | Yes | Yes |
| Where is it offered? | OpenEvidence Discover on web and app, subject to access | The iatroX game page |
| Are detailed scoring rules verified here? | Not from the public announcement | Group points, speed bonus and deductions are specified |
| What feedback is confirmed for this comparison? | A complete current post-puzzle workflow was not independently verified | Group explanations, references and an optional application question |
| What about previous editions? | Archive conditions were not verified in this review | An archive is included in the game experience |
| Does the score establish clinical competence? | No such conclusion is supported here | No; it describes this puzzle performance |
An unverified feature is not necessarily absent. The table should not be read as evidence that Synapses lacks a function simply because its public announcement does not explain it.
The useful purchasing or playing decision can still be made from the confirmed information, provided the uncertainty remains visible.
An original example of the relationship worth explaining
Consider these six terms:
Mitral valve - chordae tendineae - aortic valve - pulmonary valve - papillary muscle - tricuspid valve
Choose the four terms that form the group cardiac valves. Then split the correct group into its atrioventricular and semilunar pairs.
The four valves are mitral, tricuspid, aortic and pulmonary. The mitral and tricuspid valves form the atrioventricular pair; aortic and pulmonary form the semilunar pair. Chordae tendineae and papillary muscles are related structures, but they are not additional valves. The anatomy is described in OpenStax's heart chapter.
This is an original article exercise, not a current Synapses or clinical connections board.
The distinction illustrates what to look for in feedback: a broad relationship may make all six terms feel connected, but the intended category needs to be precise enough to account for the selected four.
The full clinical connections puzzle adds the challenge of finding four relationships within one board.
The timer changes the conditions of play
clinical connections awards 100 points per completed group, with up to 600 additional points for a successful faster finish. Errors and hints incur deductions of 50 and 100 points respectively. The game allows four incorrect submissions.
The timer continues through interruptions and reloads. That matters when deciding whether to start during an unpredictable clinical break or a quiet period when a competitive attempt is realistic.
The fastest eligible daily completion is distinct from the points score. It requires a signed-in player to complete that day's puzzle without hints, with attribution by profession and country rather than personal name. The application question is outside the timer and score.
These are iatroX rules, not claims about Synapses. No shared time-to-points formula or equivalent record system has been established in this comparison.
Hints remain a legitimate way to play. A person interested in the explanation need not treat record eligibility as the purpose of the activity.
What should happen after a relationship is revealed?
A useful explanation should let the player check whether the category is accurate and understand why a tempting alternative did not fit.
Ask whether the relationship is anatomical, mechanistic or based on a clinical association. Those are different types of connection. A group defined by an association should not silently become a claim that every member causes the same outcome.
Then ask whether the source supports the specific point. A citation to a relevant subject area is less useful than an accessible explanation of the actual relationship.
Apply this test consistently to both products. This review has not compared a sample of their completed answers, so it does not rank the accuracy or educational depth of the two libraries.
The iatroX application question is a confirmed additional task. Its presence does not, by itself, prove better retention or transfer than a different puzzle design.
Access needs a current, feature-level answer
OpenEvidence's original games announcement described free access for verified US clinicians. That launch wording should not be treated as a permanent statement that no clinician outside the US can use any part of the platform.
OpenEvidence has subsequently announced a partnership with the Medical Identification Number for Canada Corporation to support verification and free platform access for Canadian physicians.
That is enough to make a blanket exclusion of Canada inaccurate. It does not establish identical game access for every account or confirm eligibility for a UK-based reader. Nor does a store listing in a particular country prove that professional verification and all in-app features are available there.
For Synapses, check the current registration conditions and whether Games appears in the eligible account. This review did not complete a UK professional-verification test and therefore does not claim either universal UK access or universal UK exclusion.
The iatroX daily games do not require the same US professional-verification route. An account supports particular saved or competitive features, but the free activity is not presented as a trial that expires into a games subscription.
Which option makes sense for your next session?
For an existing eligible OpenEvidence user, trying Synapses inside a familiar product is a reasonable first experiment. Judge the task and explanation directly rather than assuming a familiar evidence-search brand settles their educational quality.
For someone specifically seeking the sixteen-concept grouping format, clinical connections provides that task with explicit rules and a further application question.
For a teaching organiser, predictable access and pre-reviewed content may matter more than either brand. Select an available edition in advance and ensure the group can see the relevant explanation. Do not advertise a classroom dashboard or live polling mode that has not been established.
For an examination candidate, neither daily puzzle should silently replace systematic practice. A mixed edition may reveal an interesting question without supplying balanced coverage of the required curriculum.
Add a different task rather than another near-identical score
stat complements grouping with three independent UK-context decisions. rounds offers a diagnosis revealed through progressive clues.
Those are useful alternatives when the reader wants a different kind of problem. They are not evidence that iatroX has won a general comparison with OpenEvidence, and their scores should not be combined into an informal ranking of clinical ability.
The strongest verdict is task-specific: choose a puzzle you can access, attempt it honestly and inspect the medicine behind the result. Continue because that experience is useful or enjoyable, not because the product's wider reputation has already supplied the answer.
Frequently asked questions
Is Synapses the same as OpenEvidence MedMini?
No. The games announcement describes Synapses as a tile-based diagnostic-association puzzle and MedMini as a medical mini crossword.
Can UK doctors definitely access Synapses?
This review did not verify the full UK registration and game-access pathway. Check current account eligibility rather than relying on an old blanket claim about all international users.
Is clinical connections just another name for the iatroX question bank?
No. It is a separate, complete free grouping game with its own rules and explanations. Further question-bank practice is an optional, distinct activity where relevant access and mappings are available.
