Scratch cards

If you buy the Golden Scratchers that you have to pay for with real money, you win donuts.

If you just do the free scratchers that are available every 6 hours, you win $$ - it just says: If you had chosen a golden scratcher, you would have won X donuts.

It's all marketing to get us to buy the golden ones in the hope of winning donuts.

I hope I understood your question correctly
