About and accuracy
Short version: free study games written in our own words from real university textbooks, made by a small family team. We fix confirmed mistakes quickly, and we tell you which textbook each subject follows so you can check it against your course.
Is it free?
Yes. Everything is free throughout the beta, and for all Founding Testers.
Who makes it
BioglowRX Sciences Learning is made by a small family team. Clement builds the site. Aeneas is our number one real-life tester: she's a health-sciences student studying from these same textbooks, so she plays every game first and tells us straight away if something doesn't match her course. It started as a game to help Aeneas learn the periodic table and grew chapter by chapter. Contact: clementmetz92@gmail.com.
Which textbooks each subject follows
| Subject | Follows |
|---|---|
| Chemistry | Averill & Eldredge, Chemistry: Principles, Patterns, and Applications, 1st edition (Benjamin Cummings, 2007) |
| Anatomy & Physiology | Saladin, Anatomy & Physiology: The Unity of Form and Function, 10th edition (McGraw Hill) |
| Pharmacology | Open RN, Nursing Pharmacology, Ernstmeyer & Christman, eds. (Chippewa Valley Technical College, 2020; CC BY 4.0) |
| Nutrition | Deen & Hark, eds., The Complete Guide to Nutrition in Primary Care, 1st edition (Blackwell, 2007) |
| Health & Wellness | Health-science coursework: health behaviour models, evaluating health information, introductory statistics |
Everything is written in our own words. No text, figures or questions are copied from the books; chapter numbers are there so you can find the matching chapter in your own copy.
How the content is checked
- Each game is written from its textbook chapter, then checked against the chapter and play-tested by Aeneas, our number one real-life tester.
- Before releases, automated tests open and play every game and mode on phone and desktop to catch broken questions and layouts.
- Every question has a Report a mistake button. We read every report and fix confirmed mistakes quickly; fixes are listed below.
- We are looking for a qualified subject expert to review each subject. Their name will appear here.
Units and names
Units and drug names follow the textbooks above, which are American: blood sugar in mg/dL, weights sometimes in pounds, and US generic drug names (for example acetaminophen, known as paracetamol in the UK and Europe). Where it matters, the explanation gives both.
US or UK: the US / UK button at the top of every page switches clinical units and drug names: blood sugar and cholesterol in mg/dL or mmol/L, HbA1c in % or mmol/mol, urate in mg/dL or µmol/L, patients' temperatures in °F or °C, 911 or 999, and names such as acetaminophen or paracetamol. US is the default. Spelling and the °C used in chemistry stay the same, and the dose calculations keep their US numbers (pounds to kilograms is part of the practice).
Certificates and awards
Progress certificates, subject awards, levels and trophies are a fun record of your own practice. They are not academic qualifications, course credits or proof of competence, and no school or university issues them.
How the site is organised: each subject (such as Pharmacology) has chapters that follow the textbook, and each chapter has a set of activities: quizzes, case files, calculators and more. About four of them are core activities. A chapter's progress certificate needs every core activity passed at 70% or more and at least 30 of its questions answered; the other activities are optional extra practice.
Not medical advice
The games are for learning and exam practice. They are not medical advice and must not be used to make decisions about real patients or your own health. Always follow your course, your clinical instructors and local policy.
Recent fixes
| Date | Where | What changed |
|---|---|---|
| 27 Oct 2026 | Every page | New US / UK button in the header: switch blood sugar, HbA1c, lipids, urate, patients' temperatures, the emergency number and drug names (acetaminophen or paracetamol, albuterol or salbutamol, epinephrine or adrenaline, and more) between US and UK versions. US stays the default. |
| 27 Oct 2026 | Heart Flow, Breath Path, Hormone Match, Odds On, Nutrient Rush | New: blood, clotting, cardiac output and ECG waves; gas transport and breathing control; the hypothalamus and feedback loops; hypothesis tests, confidence intervals, risk and screening (with a calculator lab); eight more nutrients and the Dietary Reference Intakes. Each adds clinic cases or exam-style questions as extra practice. |
| 27 Oct 2026 | Pharmacology | New: 18 drug cards in Drug Class Sort (DOACs, heparins, digoxin, nitrates, amiodarone, antipsychotics, lithium, phenytoin, opioids and their antagonists, newer diabetes medicines); exam-style questions (select all that apply, and what to do first) in six chapters; Dose Calc exam calculations (safe dose ranges, mcg/kg/min drips, powders, insulin). |
| 27 Oct 2026 | Syringe Prep lab | New steps: clean your hands first, swab the vial top and let it dry, inject air equal to the dose, and at the bedside match the name and date of birth on the wristband with the order (level 3 sometimes has a wristband that doesn't match). |
| 27 Oct 2026 | 20 chapters with case files | 212 case questions rewritten so the right answer is no longer the longest option and every wrong option is a believable mistake. The questions and stories are unchanged. |
| 27 Oct 2026 | Bug vs Drug, Drug Class Sort, Dose Calc | Fluoroquinolone warnings and asthma guidance worded more precisely; more correct answers kept out of the wrong options; the pounds-to-kilograms question now has one right formula. |
| 27 Oct 2026 | All chapters | Each chapter now has about four core activities that count toward its certificate; the others are extra practice. Activities are now called activities, not games. |
| 27 Oct 2026 | Drug Class Sort, Dose Calc | Answers that are also correct (for example another blood-pressure use for the same drug) are no longer offered as wrong options. |
| 27 Oct 2026 | Bug vs Drug, Drug Journey | Vancomycin monitoring updated to AUC-guided dosing; trimethoprim's selectivity explained correctly; the "-azole" naming rule now notes the exceptions; fluoroquinolone boxed warnings added. |
| 27 Oct 2026 | Drug Class Sort | Asthma cards updated to current GINA guidance (no reliever on its own); montelukast boxed warning added; metformin is "often", not always, the first tablet. |
| 27 Oct 2026 | Diet Doctor | Test for coeliac disease before going gluten-free; what to do if someone with a low can't swallow; PREDIMED retraction noted. |
| 27 Oct 2026 | pH Patrol, Fight or Rest, Pain Ladder, Energy Balance, Syringe Prep | Neutral water is pH 7 at 25 °C; bronchodilation is driven by adrenaline; opioid constipation needs a laxative; eating-disorder support signposted; the practice order uses two patient identifiers, not a bed number. |
| 26 Oct 2026 | pH Patrol | Match Pairs no longer shows each substance's pH on its card (it gave the answer away). |
| 26 Oct 2026 | Block Party | Three Match Pairs clues reworded so they no longer contain the element's name. |
| 26 Oct 2026 | Dose Calc | Medication answers no longer show trailing zeros (2 tablets, not 2.0), matching safe-writing rules. |
| 26 Oct 2026 | All chapters | A chapter certificate now also needs at least 30 questions answered in that chapter. |
