Steer falling two-part fraction capsules into the jar and line up 4 equal fractions — like 1/2, 2/4, 3/6 and 4/8 — to cure each virus fraction.
Fraction Doctor plays like Dr. Mario: two-part fraction capsules fall into a jar of virus fractions, the child steers and turns each capsule, and a line of four EQUAL fractions across or up (1/2 = 2/4 = 3/6 = 4/8) clears and cures the virus in it. Every capsule is the same colour, so the only way to match is to compare the amounts, and medicine that is not the virus's amount fizzles off with the reason (2/6 = 1/3, not 1/2), which targets the same-top or same-bottom trap; the last mode hides the viruses in unsimplified forms like 6/8 and 8/12. Gravity speeds up by level and a full jar only rinses its top rows, never ending the game. Best for Grades 3–5.
