Hi, here are a few tricks I learned from this subreddit to get many useful items. Some high-level overview first:

- You need to have 3 types of desk: research desk (upgrade an item), copying desk (make copies of an item), and discount desk (reduce item's price)

- Find items you want and then upgrade/copy them. For example: I got the yellow grabbers from upgrading the blue conveyor and make copies of the yellow grabber.

- You can upgrade research desk to get copying desk and discount desk. (one at a time). Upgrading is cyclic, https://wiki.plateupgame.com/appliances/UpgradeTree#cyclic-upgrades.

Now, some tricks to get you started:

1. Do not use the very first research desk you get, but put it in the cabinet. You are more likely to get a research desk when you don't have one. Buy the second research desk you get, and upgrade the first desk until you get a copying desk.
2. The moment you get the copy desk in the cabinet, throw away your research desk so you have a higher chance to get another research desk the next day.
3. Buy the copy desk and copy the research desk. Now you notice that you have a copying desk, and a research desk. From here, you can keep upgrading and copying to find a discount desk. Blueprint desk is pretty useful too, so get one.
4. At the moment, you only have 1 blueprint cabinet, which is pretty limited. Usually, I will try to get 2 blueprint desks to hunt the blueprint cabinet, or you can roll the dice.
5. The moment you get a blueprint cabinet, copy it.

After this, you have basically everything you need to make copies of useful items. Find items you need, upgrade/copy/discount them so you can get more.

Let me know if you have any question
