About Word Labyrinth
Word Labyrinth is a free daily word-ladder puzzle game for the web, iOS and Android, published by CoreDL d.o.o. We built it to bring Lewis Carroll's 1879 puzzle to a modern audience — with daily ladders, leaderboards, streaks, and a beautifully tactile interface.
What we built
Word Labyrinth is the modern incarnation of the word ladder — the puzzle Lewis Carroll invented as Doublets on Christmas Day 1877. The rules have not changed in nearly 150 years: change one letter at a time, every word must be real, get from start to target. What we have changed is the experience around the rules:
- 5 fresh daily puzzles, the same for every player worldwide.
- A global leaderboard and a tier-based rating system.
- Streaks with milestone rewards at 3, 7, 14, 30, 60, 100 and 365 days.
- Hints that reveal the next letter on an optimal path — for when a puzzle has you stuck.
- An Expert mode with unlimited high-difficulty puzzles.
- A clean, distraction-free interface on web, iOS, and Android.
Why we built it
Word ladders are one of the oldest word puzzles in English and one of the most under-appreciated. They reward vocabulary breadth, planning, and pattern recognition in equal measure. They have a graceful underlying mathematics — the word graph — that turns every puzzle into a small computer-science problem. They are also genuinely fun: the moment a tricky bridge word clicks into place is a quiet, particular pleasure.
We thought the puzzle deserved a mobile-first daily home with the same care as Wordle and the New York Times Crossword. So we built Word Labyrinth.
The team
Word Labyrinth is built by CoreDL d.o.o., a small studio based in Croatia. We are a tiny team of word-puzzle players, software engineers, and designers. We do everything ourselves: the puzzles, the dictionary curation, the algorithms, the apps, the artwork. If you have feedback, we read every email.
What's next
Our roadmap includes:
- Multilingual word ladders — Croatian first, then Spanish, French, German.
- Themed weekly puzzles — chains that tell a tiny story (e.g. WINTER → SUMMER through the months).
- Friend leagues — private leaderboards with friends.
- Puzzle archive — replay past daily ladders any time.
- Better accessibility — improved screen reader support, dyslexia-friendly font option.
