Astrology 101

Astrology 101 is a single-player game about learning astrology from the ground up.

It won't make your decisions and it won't predict your future. It teaches you to read a birth chart: how twelve signs, ten bodies, twelve houses and five major aspects talk to each other — then it puts your own moment of birth into that chart, so you can watch the language reflect you back.

Six tiers, 48 lessons: from the zodiac wheel to a full reading

The course moves through six tiers: Chart foundations → The twelve signs → The ten planets → The twelve houses → Aspects & patterns → Reading & transits. Every lesson is a short passage with a chart example, followed by four kinds of practice — multiple choice, symbol recognition, concept matching, and ordering the zodiac. Nothing is gated behind a quiz; your progress saves on your own machine at any time.

Cast your own birth chart

Enter a date, a time and a city and the game assembles your chart: each body's sign and degree, the twelve house cusps, the four angles (Ascendant / Midheaven / Descendant / Imum Coeli), dignity and retrograde states, and a strength ranking — all drawn on a chart wheel you can zoom into.

An eight-chapter report where every claim shows its evidence

The report comes from a rule engine, not a black box. After a summary and three highlights (Big Three / chart ruler / strongest planet) come eight chapters: Personality core, Chart ruler, Mind & communication, Love & relationship, Drive & desire, Growth & structure, Gifts & challenges, Shape & emphasis. Under every conclusion sits its "astrological basis" — the exact degrees, houses and aspects behind it, so you can check the reasoning yourself.

A codex you can browse anytime
