I felt a bit cheated – Cooking Day: Master World Chef Review

Once you reach advanced levels, no matter how hard and fast you try to serve customers, in the end you are almost definitely going to see a pop up saying something like, “ Do you want to add 40 seconds”. If you hit No, you are not going to cross that level. If you hit yes, some diamonds will be deducted from your balance and no matter how poorly you perform in that extra time you are always going to make it to next level. This way gradually you exhaust your diamonds deposit and either you have to buy diamonds or keep playing that level for like 100 times and you might succeed once.
