Chengel
An AI-powered word puzzle that brings the traditional Turkish crossword format to mobile: endless generated boards, daily competition, and a streak system that keeps players coming back.
Overview
Chengel is the digital home of Turkey's beloved crossword format. Where the newspaper version runs out after you finish it, Chengel never does. An LLM generates fresh puzzles continuously, calibrated for difficulty and vocabulary range.
The Problem
Turkish word puzzle players were stuck with finite content: one puzzle per day in newspapers, no replay, no progression. There was no mobile-native product that respected the format while making it genuinely endless.
What We Built
An AI-powered generation pipeline that creates valid Turkish crossword grids on demand. A daily competition mode for players who want stakes. A streak system for players who want ritual. Cloud sync to carry progress across devices. Built in Flutter for a smooth, native iOS feel.
Status
Live on the App Store. Actively maintained with regular puzzle generation improvements and leaderboard updates.
