It is for players who like Sudoku, Mahjong, pattern recognition, quiet puzzle games, and brainy logic challenges. ## Product Hunt Timing Current status: Draft created on Product Hunt.

The rules are still classic Sudoku: every row, column, and 3x3 area needs one of each value. But instead of only reading digits, you solve with Mahjong-style tile suits like dots, bamboo, and characters.

Developer: William Lock I would love feedback from puzzle players: do Mahjong-style symbols make Sudoku more interesting, or do numbers still feel easier to solve? ## Reddit / Developer Forum Post Do not post this immediately on Reddit. The earlier Turbo SSHuttle post from u/LockStudio was filtered, so use this only later where self-promotion is clearly allowed. I built Mahjong Sudoku Classic because I’m a Sudoku fan, and I wanted to combine single-solution Sudoku logic with Chinese Mahjong tile visuals. When solving normal Sudoku with numbers 1-9, some puzzles can get difficult in a very abstract way. I started wondering whether replacing the numbers with Mahjong-style tiles would make the board feel more visual and more challenging. The rule system is still Sudoku: each row, column, and 3x3 area needs one of each tile from 1 to 9. The difference is the visual language. Instead of a plain number grid, the board can use Mahjong suits like dots, bamboo, and characters. I also liked the idea of connecting Mahjong players with people who enjoy brainy logic games.

Developer: William Lock Feedback from puzzle players would be helpful: do Mahjong symbols make Sudoku more interesting, or do numbers remain easier to solve? ## Product Hunt / Indie Hackers Comment I am experimenting with a puzzle idea from my own Sudoku habit: classic single-solution Sudoku rules, but with Chinese Mahjong-inspired tile suits instead of normal digits. I wanted to see whether this makes the board more visual and interesting for both Sudoku players and Mahjong fans. ## Product Hunt Launch Day Post Mahjong Sudoku Classic is live on Product Hunt. I made it because I’m a Sudoku fan, and I wanted to see what would happen if the usual 1-9 grid became Mahjong-style tile suits. The rules are still classic Sudoku: every row, column, and 3x3 area needs one of each value. The difference is the visual language. I’d love feedback from puzzle players: do Mahjong-style symbols make Sudoku feel fresher, or are numbers still easier to solve?
