Five game mechanics, thousands of years old, replayed with words that didn't exist three years ago. Every mechanic below was independently invented by multiple civilizations — the lexicon just gives them new fuel.
Pompeii, before AD 79 · the oldest surviving word puzzle
A · The Square of Five Words
A five-by-five Latin palindrome scratched on Pompeii's walls, found from Rome to Syria: SATOR · AREPO · TENET · OPERA · ROTAS. It reads the same across rows and columns, forwards and backwards — the Roman Empire's favorite meme.
Explore: tap a direction. Every direction reads five valid words. Rows and columns are identical — that's the trick, and nobody knows why it was made.

~2,000 years old · and still unsolved: “Arepo” appears nowhere else in all of Latin literature.
Greece ~300 BC (Lycophron's anagrams) · Han China ~AD 200 (Kong Rong's Lihe poems)
B · Fusion Riddle · Lihe
The oldest word-building game: break a name or word into fragments and fuse them back. Han-dynasty poets hid names in Lihe poems; Greek poets wrote verse-anagrams of royal names. AI-coined words are fusions by birth — so the game rebuilds itself.
Play: the meaning is given. Click the fragments that fuse into the coinage — but some of the fragments are decoys that don't belong.
The mutual opacity of people who have shared a building for years without ever learning each other's names.

Tang China · Feihualing, the scholars' wine game
C · Flower Order · Feihualing
At Tang-dynasty banquets, the drink-master fixed one character — say hua, “flower” — and everyone took turns reciting a verse containing it; hesitate and you drink. Today the character comes from the lexicon, and the “verses” are AI-coined words.
Play: one required morpheme. In 45 seconds, click every tile on the board that hides it — most tiles don't. Each hit reveals its definition; at the end, the ones you missed are outlined.
Pick a morpheme above to start the round.
Sumer ~1800 BC · Sphinx · Exeter Book ~AD 1000
D · Reverse Riddle — you coin the word
The riddle is humanity's oldest word game: a meaning described, an answer to be named. This time you are the answer-writer. Given a definition and its raw morphemes, coin your own word — then see what the AI actually coined.
Play: read the definition, then coin your word — click one of the suggested coinages below (one of them is the AI's actual choice, but we're not telling which) or type your own fusion. Then compare with the machine.
A subgroup chat within a family that deliberately excludes certain relatives.

Japan Shiritori · Korea Kkeutmareugi · Russia Goroda · India Antakshari
E · Word Chain · Jielong
Independently invented on four continents: each word must connect to the last — by final syllable in Tokyo, last letter in Seoul, city name in Moscow, first sound of a song in Delhi. The lexicon version connects by hidden letter-runs buried inside the words.
Play: pick the one word that shares a hidden run of ≥5 letters with the current word. Find it, the run lights up, the chain grows. Three wrong picks and the chain snaps.
