Named after Kaprekar's Constant (6174), where logic always reaches a single distinct answer. No ads, no premium costs, just years of free daily play.
A daily 5x5 word grid puzzle. Deduce the 5 row words and 5 column words before your tokens run out!
You get pre-filled clue rows, can you deduce the only viable answer? Add more clues but lower your elo ranking, in this risk reward word deduction game.
Rotate, flip, and stack 3 transparent geometric shapes to match target silhouettes. Features Daily Challenge, 4-Player Head-to-Head, and Challenge a Friend.
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.
In math, 6174 is Kaprekar's Constant. If you take any four-digit number with at least two different digits, sort the digits in descending and ascending order, and subtract the smaller from the larger, you will always hit 6174 within 7 steps. Every puzzle on this site works on that same principle: every single board has exactly ONE unique solution.
SQORDY is a daily 5x5 word square puzzle. 5 horizontal and 5 vertical words interlock. You solve the grid using letter clues for rows and columns while keeping an eye on your token count.
ONE SHOT is a daily word deduction game. You get pre-filled clue rows with color feedback, and you have to deduce the 5-letter answer in one guess across Easy, Medium, and Hard tiers.
Every puzzle is generated and tested by custom algorithms against the dictionary to make sure there are no duplicate solutions or broken clues.
No ads, no accounts, and no tracking. Everything runs right in your browser, and you can sync your stats to another device anytime using a simple sync code.
In math, 6174 is Kaprekar's Constant: an operation on four-digit numbers that always converges to the exact same number in 7 steps or less.
I built 6174 Games because most daily word games felt too quick and forgiving. When the difference between you and your friends comes down to 2 or 3 seconds on a simple board, it stops feeling rewarding. I wanted puzzles with real teeth, where you can actually get stumped and face a genuine threat of losing.
Using graph algorithms and constraint solvers, every single daily puzzle is computationally verified against the dictionary to have only ONE true solution. You can approach the logic from multiple angles, but you will never lose to ambiguous clues or multi-answer flaws.
A lot of daily games test how fast you can type an easy answer. In SQORDY, you have to balance a 5x5 interlocking grid with a tight token limit. In ONE SHOT, you get one single shot to deduce the word from clues, with Elo rating on the line.
Generating non-mirrored 5x5 word squares that use everyday words is a computationally heavy problem. We use custom graph search algorithms to verify millions of combinations against the full US Scrabble dictionary, while ensuring target solutions use common, recognizable words.
Yes. Every board across all games is algorithmically verified to guarantee that exactly one unique answer satisfies all constraints.
None. Everything runs client-side in your browser, your stats stay on your device, and there are years of daily puzzles ready to play.
