Any website to create gamification marketing without code?

I looked through Product Hunt, but I couldn't find any products that let me create gamification marketing using drag and drop without the need for code. I previously asked a similar question on Reddit, but all I got was advice to use Kahoot. What I need, though, is a game that can be altered by dragging and dropping elements to make it appear like a game similar to Flappy Bird but is used for a particular brand's marketing. Users will receive brand vouchers, for instance, when they play games and win (based on points).
