Do you know when it happened?
Kairoza hands you a card and asks one question: where does it belong on the timeline?
Before Gutenberg's printing press, or after? Before Pelé won the World Cup at seventeen,
or after?
One card at a time. You pick a slot and you find out at once — the date flips over and the
card locks into place, or the card that contradicts it lights up and tells you why.
• 306 real events, every one checked against a reference source
• 200 levels across 10 themes: inventions, wars, arts, sciences, space, sport, screen,
exploration, everyday life, medicine
• The difficulty grows inside each level: two slots for the first card, then three, then four
• Revisit any level you have solved — the full order, the dates, and what each event changed
• Plays offline. No account, no sign-up
• Events and interface in 12 languages
• Music and sound effects, both switchable
Nothing here is invented. Every event is verified before it enters the game, and the cards
name the people: Gutenberg, Marie Curie, Laennec, Mendeleev, Nelson, Fosbury.
Put history in order. 306 real events, 200 levels, 10 themes.
