About RatioRealm Play

How it works

RatioRealm is about comparing two amounts — and scaling that comparison up and down without breaking it.

• Ratio Studio — scale a ratio to a target on a double number line and ratio table (multiply BOTH numbers by the same factor), and mark a part of a whole as a percent.
• Scale Workshop — the same idea in real life: scale a recipe, a map distance, or a blueprint measurement by the scale factor.
• Relative Reasoning — decide which mix is stronger by its share, not its size. A bigger drink isn't always the more flavorful one — that's the heart of proportional thinking.
• Concept kits — 16 short question rounds, from an intro to ratios up to advanced synthesis.

Our privacy promise

RatioRealm Play is free, works offline, and collects nothing. No accounts, no ads, no tracking, and no data ever leaves your device — your progress, level, and streak are saved only in this browser.

Mistakes are part of it

You never lose anything for a wrong try. Wrong answers get a gentle explanation, and hints teach you how to think it through — not just the answer.
