# 6174 Games

> 6174 Games (https://6174games.com) is a free daily puzzle site. Named after Kaprekar's Constant (6174), where numbers always reach the exact same value, every puzzle has exactly ONE valid solution.

## Philosophy

6174 Games are built out of a desire to understand complex mathematical interactions and write algorithms that solve those problems efficiently and effectively. This leads to problems that take time, are tough, but bring with them a great sense of satisfaction when you succeed! It's not about being 5 seconds faster than your friends, it's about being able to solve something genuinely difficult which required serious effort for an algorithm to determine.

- Graph algorithms and constraint solvers: Hard problems, like generating non-mirrored 5x5 word squares of everyday words, are solved with custom algorithms and checked against the full dictionary.
- One unique solution: Every puzzle is tested so you never run into ambiguous clues or multiple answers.
- 100% Client-Side: No ads, no tracking cookies, and no accounts.
