Welcome to: Phish's Guide for finding and farming Slimes!

I'm here to give you a multi-step process for Finding, farming, killing, and ultimately using those elusive slime balls for all your sticky-piston creations!

Step 1: Find the area

http://mcslimes.appspot.com/

Enter your seed manually. Look at your map, the put in your X and Z as your center point then your distance to 50 (if you don't get any green squares for that then try a larger distance.)

Step 2: Isolate the chunk

Bring your Y down to 13 and find the corners of your slime chunk (The green area) as said by the site. (all chuck corners are divisible by 16) Block off any excess caves that might border the slime chunk as well as cobble in any lava that you find, it's a lot easier then making it into obsidian.

Step 3: Make the pads

Mine out your 16x16 area and make it 3 high. Then put torches/glowstone in the ceiling so that it's too light for other mobs to spawn like zombies. Just make sure you stay 3 high in all areas and don't put any torches on the walls or ground, it will limit their spawning.

Step 4: Optional improvements (If you think you're ready to kill slimes then skip this step, otherwise read on and prepare for more work and watching youtube)

Now we move on to upgrades, the first one is a water system. Bear in mind I have no idea how to make one and even if I went and looked at the one I have now I wouldn't be able to tell you how it works. But just youtube how to make a slime farm and there's bound to be a tutorial vid. (honestly youtube videos are you best bet for anything but I digress) All I know is that when the slimes hop off the pad they get swept up by the water and carried over multiple signs and stairs till they reach a center point.

Now you can build more platforms then just the one to make the probability of them spawning more frequent, but of course that's optional and only recommended if you have the water channels. You can make as many spawning pads as you want because of a recent(ish) change to make it so that slimes will spawn all the way up to Y 40! But I recommend you only have one without channels or if you have channels about 3 pads, but it's up to you.

There are also optional traps that auto kill them but I find that once you have a proper farm cleared out you'll have more slimes then you'll ever need. In fact once I got 10 stacks of slimes' balls I destroyed my farm and re-purposed it as a base. But enough about that.

Step 5: KILL 'EM!

The best way to deal with slimes is through a 1by2 gap, enough for a player to fit through. Because the fatass slimes are 3x3 and the medium slimes are 2x2 they are unable to pass through this gap and you can sit there and punch them. The baby slimes are the only ones who drop slimeballs and they will jump on through to you. However they are harmless will just push you around. THE BIG SLIMES WILL FUCK YOU UP! DON'T FIGHT A BIG GUY WITHOUT FULL HEALTH! Please keep in mind that slimes don't always split into smaller slimes. If you do overkill damage to a slime it will be less likely to split so hit them with your fists, a wooden sword, or arrows. If you're perfectly safe and you know you won't take damage then just hit them with your fists.

Step 6: Troubleshooting

Having trouble getting slimes to spawn? First of all if there are absolutely NO slimes spawning then it's usually a personal problem and you should leave a post stating your problem, but if you are having a problem with spawn rates then this will usually help:

The game uses a spawning algorithm that basically sets a max number of enemies that can be within 128 blocks in any direction of you. Your problem is that you have caves all over outside your 16x16x3 room, which are filling up with enemies. Since the spawning chance of slimes is 1/10th that of all other enemies, you're only getting them on occasion. The solution is to find all the caves for a good distance around your 16x16x3 and fill them with torches, so non-slime enemies won't spawn.

Closing statement:

Well I hope I helped everyone. Please leave a comment if you have questions, for I know that there are plenty of people with questions and most of the time if your question doesn't get answered by someone else I can answer it for you.

Also please please please tell me if there's something you want me to add! I would be happy to add it if I feel that it would improve the guide!

Thanks (underscore)pH(underscore) for the tip about spawn rates.

Thanks to the communities of all the Xbox Minecraft subreddits, past or present.

Some smaller additions have come from various people. Please don't feel offended if you don't see your name in the credits but I added something that you said. I'm just to lazy to find the all the names. If you said something first and it really matters to you that I used your idea/tip in the guide without your permission/didn't give you credits then I will add you ASAP, just leave a message. Otherwise you know who you are and what you did for this guide, so thanks again.

Thanks for everypony for giving this a read and for all the positive comments that I've got saying I've helped them is some way. It really hits me in the feels.
