Yearmoss: History Trivia Cards

A history trivia card game about what comes next: grow a moss vine through history with the event that happens next, and wither the cards time has already passed. Free, no ads, no tracking; mouse, touch, keyboard or gamepad, in English or Bulgarian.

A moss vine climbs the wall of an old archive; its tip shows one event with its year. You hold four cards with their years hidden. Each turn, do one thing with one card: grow it if it is the next event after the tip among your cards, or wither it if time has already passed it. Grow a later card while an earlier one waits in your hand and the vine jumps: the cards it skipped are now in the past.

• 149 events checked against their dates, from 79 AD to 2026
• Two moves, real choices: which card comes next, and which is already behind you? A miss costs one of three hearts and shows the true year
• A guided warm-up that teaches growing, jumping and withering in its first moves
• Eight themed chapters (inventions, space, science, books and art, music and film, sport, world history, Bulgaria) with up to three stars, and an endless grand mix in climbs of 16 cards
• Streaks bloom ×2 and ×3; every third compost earns a century hint
• Save slots and autosave; settings for sound, reduced motion, high contrast, larger text and keys
• Keyboard, mouse, touch or gamepad, in English or Bulgarian

Code and text written with AI assistance; checked by PN Scripts with automated tests. Every shape is drawn and every sound synthesised by code; there are no AI-generated image or audio files.
