Merdiven

Starting from a start word, you reach the target word by changing only one letter at each step. Every intermediate word has to be in the dictionary. The game has a 365-day puzzle set, 4- and 5-letter modes and an endless mode. TDK (Turkish Language Association) meanings are shown and players can suggest new words.

Highlights: A new puzzle every day; 365 puzzles were produced for the whole year. Word validation uses TDK and runs server-side with Vercel Functions. A PWA that opens offline.
