The fact that it has been "Approved" before only indicates that someone simply forgot to check your hunt.

PG 5. There are countless games worldwide, and many of them have narrow target customers. If we accept all new games in Steemhunt, our ranking board may be dominated by games.

So, Steemhunt will only accept games that are:

• Downloadable/purchasable games
• run on their own website
• a game platform itself, rather than a single game inside the platform.

These specific types of games will not be acceptable:

• A single arcade game
• A single flash / HTML game
• A generic gambling game

Have a great day.
