## Main Angle

Lead with the real story:

I am a Sudoku fan. Normal 1-9 Sudoku can become abstract and difficult, so I wondered whether Chinese Mahjong tiles could make the puzzle more visual, more challenging, and more interesting for both Mahjong players and Sudoku players.

## Best Channels

1. Rednote / Xiaohongshu
2. Product Hunt
3. Indie Hackers
4. Reddit, later and carefully

## Rednote

Use:

Title:
我是数独迷，所以做了一个麻将数独

Ask for feedback:
麻将牌面是让数独更好玩，还是更难？

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。

QR code:
Do not use QR codes in the Rednote image or post. Keep the post safer and simpler by asking users to search the App Store and recognize the icon.

## Product Hunt

Status:
Draft created on Product Hunt. Keep it as a draft until the Turbo SSHuttle launch activity settles.

Use:
https://williamlock.github.io/Mahjong-Sudoku-Site/product-hunt-draft.md

Draft URL:
https://www.producthunt.com/products/mahjong-sudoku-classic?launch=mahjong-sudoku-classic

Frame it as a simple puzzle experiment:

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

Ask:
Does the tile visual language make the puzzle feel fresher, or do numbers remain easier to solve?

Timing:
Do not launch on the same day as Turbo SSHuttle. Recommended separate launch date: Tuesday, June 23, 2026, with manual promotion between 8:00am and 10:00am PT.

## Indie Hackers

Use the builder angle:

I built a small puzzle app from my own Sudoku habit and tried to combine it with Mahjong visual language.

Good question:
How do you decide when a puzzle variation is meaningful enough to become its own app?

## Reddit

Do not post Mahjong Sudoku immediately from the new account. The earlier Turbo SSHuttle post from u/LockStudio was filtered by Reddit, so use Reddit slowly and avoid link-heavy launch posts for now.

Later, use a soft feedback title:

Feedback wanted: Sudoku with Mahjong tile symbols

Avoid multiple links. Use either the founder story or the App Store link, not both. It is better to start by commenting naturally in puzzle, Sudoku, Mac, or maker discussions before posting another product thread.
