I logged into Wizardess Heart yesterday and saw an ad for "Win His Heart Slots." Apparently, it's a new slot game where you can win CGs from the some of popular Shall We Date App otomes such as: Wizardess Heart; Blood in Roses; Guard Me, Sherlock; Love Tangle; Ninja Assassin.
I clicked through the link from Wizardess Heart and got 1,000,000 points after the download. Also, Klaus Goldstein's slot is available for download for a short time... today is the last day, maybe?
Overall, it's kind of a clunky, slow app. Not terrible but gets boring awfully fast in my opinion. I would suggest that you try it out if you're interested. At least the cute guys have a bit more movement as they cheer you on if you win than the usual static pictures from the otomes. Randy's slot has Taffy instead of Randy. I like Taffy so no complaints.
I'm not sure exactly where this concept came from or where it'll go from here so I'll keep the download for now in case something fun develops.
Try it out and let me know what you think!
