Here's how I did 4/20 mode in Fred Bears 83 reborn.

1. Once the night starts instantly type seal _vent.

2. Focus on the main important cameras that you need to you need to beat this max mode. To tell which cameras are important, I will tell you which one you need to focus B01 B02 B03 and A04. B01 is where you look for Spring Foxy in the room. B02 is where you look for the storage room. B03 is where you look for the party room. And finally, A04 is where you look for the vent. Checking the camera B02 is not necessary only. if spring Bonnie escapes from B03. If Spring Bonnie got away from B03 he will move to B02. So you have a chance to catch him.

3. Always check on Spring Foxy. This will slow him down even without the Flash Beacon. So don't waste your flash beacon on him.

4. If Spring Bonnie enters the event, you have a lot of time to deal with the other animatronics. As soon as you seal the vent immediately. type the same seal_vent and repeat this process. When every time you seal the vent, if spring Bonnie enters in the vent, immediately type seal _vent. This will give you a lot of time while typing.

5. And repair your equipment instantly.

6. If the endoskeleton is bothering you while you're repairing. Flash the light on him and repair the equipment at the same time and then turn off the light back. This will save enough overheating problem from your light.

7. If both FredBear and spring Bonnie showed up in the party room at the same time, you already. know what to do. Do it at once. Flash the Beacon and use the audio at the same time.

8. And pray that spring Bonnie goes in the kitchen a lot so you can have a lot of time to deal with so much small RNG.

9. And always deal with FredBear fast enough as he wont give you no chance.
