I have not. There are 2 games I'm currently playing here on Steemit that have chance of offering some rewards here .

One is called steempunknet. Its a extension you download for your Brower and you play it on steemit. Boxes can spawn that you open on peoples blogs and comments that can have armour/weapons. There main blog page is also spawning zone for crafting items.

The other is steemnova its a browser game. Top players can earn a little bit of post rewards I think.

I might make a guide for both in future. Will have see how my time is after this completion.

Do you play any games?
