## Current Status

The Product Hunt draft is created.

Do not launch Mahjong Sudoku Classic on the same day as Turbo SSHuttle. Give each product a separate attention window.

Recommended launch date:
Tuesday, June 23, 2026

Recommended Product Hunt launch time:
12:01 AM PT

Best manual promotion window:
8:00 AM-10:00 AM PT

## Main Goal

Present Mahjong Sudoku Classic as a small, personal puzzle experiment:

Classic single-solution Sudoku logic, but with Chinese Mahjong-inspired tile symbols instead of normal digits.

Ask for puzzle feedback rather than only downloads.

## Morning Sequence

1. Open the Product Hunt draft and confirm the launch page is live.
2. Check that the first maker comment is visible.
3. Share the Product Hunt link from the share kit and personal channels.
4. Post the Rednote story using the vertical image.
5. Add useful Indie Hackers comments if direct posting is still limited.
6. Avoid Reddit on launch day unless the account has more natural activity and the subreddit rules clearly allow it.
7. Recheck Product Hunt comments every 30-60 minutes during the day.

## Product Hunt Focus

Good question:
Do Mahjong-style tile symbols make Sudoku feel fresher, or do numbers remain easier to solve?

Reply topics:
- Sudoku difficulty
- symbol recognition
- Mahjong visual language
- whether tile suits make the board more memorable
- whether puzzle players prefer numbers or icons

## Short English 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?

Title:
我是数独迷，所以做了一个麻将数独

Search clue:
App Store 搜索 Mahjong Sudoku Classic。认准浅色数独棋盘图标，中间有一张麻将牌，上面有彩色圆点。开发者是 William Lock。

Do not use QR codes. Keep the post simple and safer by asking users to search the App Store and recognize the icon.

## Reddit Guidance

Do not post Mahjong Sudoku immediately from the new Reddit account.

The earlier Turbo SSHuttle post from u/LockStudio was filtered by Reddit. Use Reddit slowly:

- comment naturally first
- avoid multiple links
- use one soft feedback question later
- do not post the same product message across multiple subreddits

Later title:
Feedback wanted: Sudoku with Mahjong tile symbols
