Using Opus 5 to create ads for my web-games

I recently released MentalRoyale.com, a collection of brain training games playable in the browser. This was a project I build completely with AI, just to see how far I could get.

In previous years I would have spend 5-10K for this site and also a lot of hours to discuss all the adjustments and decisions with the developer, it would be a constant back and forth, now I have the same interaction with AI but it’s a lot more efficient using the “grilling”-skill. I really love this kind of interaction because claude shows me my blindspots and things I have overlooked or didn’t even think about.

To promote my new site, I wanted to show ads to my users on 10FastFingers. There is a lot of un-monetized traffic (usually from Tier3 countries/asia) on 10FastFingers and I wanted to capture those impressions and at least promote a product that was of similar interest to the audience.

I’m a developer and doing marketing or creating ads is really hard for me, so I prompted Opus 5 to just create a couple of ads of my games. Because the game code was already available, it just “played” a version of the game and generated ads from it, here are a couple of examples:

Make 10

Sudoku

Overall I let claude create multiple ads for each game, which would have taken me at least a couple of days to do it myself (and tbh I wouldn’t have had the same creative output).
