Kaladont

Kaladont, also spelled kalodont, is a South Slavic word game popular in Croatia, Montenegro, Serbia, Slovenia, Bosnia and Herzegovina and North Macedonia. Players take turns saying words, and each new word must begin with the last two letters of the word that came before it. A valid word must have at least four letters, must be a standard dictionary word rather than a made-up term or proper name, and may not repeat a word already used earlier in the round. A player who cannot produce a valid word loses. Play can also end in a distinctive way: once a word ending in the letters '-ka' is spoken, the first player to shout 'kaladont' wins outright, since no word in any of the South Slavic languages begins with the letters 'nt'.
