Wicked Game is a purple/green/grey duochrome that is often described as looking like an oil slick. Application wasn't great. It dries to a chrome finish so it shows every imperfection. It also bubbled like crazy. Sad. Anyway, photo time:
Despite the application issues, I like it. It has a very strong duochrome effect, and I love the colours it shifts to (even the green!). There are various similar, if not identical, polishes out there though - so if you're not willing to splurge on this brand, I believe Wet n Wild Anatomy, Essence Where's the Party?, OPI Not Like the Movies and Nubar Purple Beach are all quite close.
