Who Is the Best AI Assistant for Sudoku Master Puzzles?

By puz.gg team | Sep 03, 2025

When you play a tricky Sudoku game, wondering if AI could save the time? With so many AI assistants claiming to be genius problem-solvers, we decided to make a test. We put three popular AI together - ChatGPT, Doubao, and DeepSeek. We took a challenging Sudoku puzzle from Daily Sudoku (yep, one that's totally solvable!) and asked each AI to crack it. The result? Well...let's just say it wasn't exactly what we expected! 😅

Let's dive into how each AI performed—and why you might still want to rely on that amazing human brain of yours!

Sudoku For the AI Players

This sodoku is the hardest level in our game
We take the screenshot below and send the the AI players

Let's check their performance.

1. ChatGPT: The Creative Mind Struggles with Numbers

We started with ChatGPT, known for its conversational flair and broad knowledge. We pasted the Sudoku grid and asked for a step-by-step solution.
ChatGPT politely explained Sudoku rules, attempted to describe a solving strategy, but eventually gave up with a "This puzzle seems highly constrained" message. No solution — just a gentle retreat!
Verdict: Great at talking about Sudoku, not so great at actually solving it. Maybe stick to writing poems instead of number-crunching!

2. Doubao: The Friendly Helper Who Prefers Small Talk

Next up, Doubao — a popular Chinese AI assistant praised for its user-friendly vibe. We submitted the same puzzle, hoping for a different outcome.
Doubao recognized it was a Sudoku puzzle (good start!) and generated a colorful grid...with multiple errors. It missed hidden pairs and misapplied elimination rules, leading to an invalid solution. Oops!
Verdict: Super friendly and encouraging, but its number skills need work. Better at chatting than solving!

3. DeepSeek: The Logic Wizard Who Overpromised

Last, we tried DeepSeek, an AI built for reasoning and technical tasks. We had high hopes!
DeepSeek analyzed the puzzle confidently, generated a full grid...but made a classic mistake: repeating numbers in a row! It even offered a "solution" that broke Sudoku's basic rules.
Verdict: Strong on confidence, weak on execution. Maybe stick to coding instead of puzzles!

So...Who's the Winner?

None of them! In fact, we solved this puzzle manually. While these AIs are brilliant at many tasks, Sudoku Master-level puzzles still require human intuition, pattern recognition, and patience. That's where the real fun begins—and why solving puzzles yourself is so satisfying!

If you're looking for tough-but-fair Sudoku challenges (you know, the kind humans actually designed), check out our game on Puz.gg. We've got everything from Easy to Extreme—no AI needed, just your clever brain!

AI assistants are amazing, but even the smartest bots aren't perfect Sudoku solvers...yet! Whether you're a beginner or a Sudoku master, nothing beats the thrill of cracking a puzzle yourself.
