All Working Stardew Valley Exploits:
1. Infinite Free Cinder Shard Exploit

There is a glitch with cinder shards! A glitch so powerful that you will literally never need to farm for these again.
You see Cinder shards are a rare resource and you need quite a few of these to enchant all of your weapons, tools and rings.. However if you ever actually use your cinder shards, you are making a huge mistake.
Abuse this glitch Instead If you click the button to forge, and immediately pick up the cinder shards from your inventory. You will get the upgrade, and the forge will not eat your cinder shards.. Use this exploit if you want to enchant literally everything without grinding for any cinder shards ever again.
2. Unlimited Hay Exploit.

Okay Hear me out. If you love animals, then you will need tons of hay! And the best way to get hay is by harvesting it yourself with grass. Why would you ever buy hay from Marnie and be scammed am I right?
Well there is a broken glitch that will literally let you swim in hay. All you need to do is place down some grass using grass starters on the last day of winter. Blue grass for the best result! Then when you sleep, spring will appear and every spot of grass will multiply! You will have more grass than you will ever need!!
You can then harvest all of that grass, and make sure you have enough space in your silos because this is absolutely crazy.
3. Out Of Bounds Glitch In Stardew Valley.

Stardew valley has this little out of bounds glitch. Just stand at the edge of the map with a sword and swing it as fast as you can without moving. Then yeah, you’ll be out of bounds. You can use it on the second day in a playthrough to get the iridium Krobus statue! You’d usually need to be level ten fishing for this so that is pretty cool.
This glitch does still work, but Mr Concerned Ape added a little secret for those of you who abuse it. If you use it to get to the summit before reaching perfection.. Well, Mr Qi will attack you and you’ll wake up at the doctor. Quite interesting if you ask me .
4. Unlimited Ice Cream with Stardew Valley Horse Glitch.

Do you want ice cream? Is Alex being lazy and not selling ice cream!! Just exploit the game! Just grab a horse and park them right over here, just behind the ice cream stand., your horse will now become the ice cream vendor! Allowing you to buy ice cream.
A decent solution, but there is a more permanent one. Instead, use a slime egg incubator and hatch a slime right there! Inside of the ice cream stand! Now the slime will become the vendor and will sell you ice cream year round! This is exactly what I needed, this is exactly what we all needed.
5. Stardew Valley Item Id Exploit (Duplication glitch)

The most dangerous and most impactful glitch in this game is the Item Id glitch. However this glitch has been upgraded to be even more broken! Let me show you the basics first. Just name your character this, and whenever someone says your name you’ll suddenly get those items in your inventory!
We can use this sequence [163][166][417] and then just call Clint on the phone and every time he answers, you will get some of the most expensive items every single time.. If you do prefer to have a real name, then buy a chicken and name it seventy four for example for a prismatic shard! I am actually quite surprised that this has not been patched out as of yet.. It is the most dangerous after all.
Now for the upgraded version!! Use this new code here. [(BC)272] Then just get someone to say your name and there we go. You now have an auto petter. The gosh darn rarest item in the game. Comment down below if you have found an auto grabber the legit way.
6. Chair Secret Woods Glitch.

What do you do every morning in Stardew Valley? I go and get my wood hard. I mean, my hardwood.. At the secret forest of course. As you know you can get twelve logs here every single day, but only after you have upgraded your axe enough to get past this large log!
Well, with the help of a chair and an axe that was only upgraded once, you can simply bypass this log and get that wood earlier than you’d usually be able to. As a bonus you can also get fiddle ferns earlier using this method. You can also use this glitch to get through Marnie’s door to get Mayor Lewis’s Shorts Earlier! You can’t get back so bring a farm warp totem or simply pass out I guess.
7. Unlimited Free Qi Gems Stardew Valley Exploit

Alright listen here, Mr Qi has so many incredible items for sale and we need them all! The problem is that we can only really get Qi Gems by doing these quite tedious Special Order Requests.
These quests are not necessarily difficult however they are tedious! We do not have time to dilly dally. Just exploit the game for maximum reward!!! There is a qi gem glitch that will make your life forever easier.
Okay it’s simple, go get a bunch of Golden Walnuts. As many as you possibly can. Then open up the chat window by clicking T on keyboards or Click in the right joystick on controllers and then simply type forward slash recountnuts. -> /recountnuts
This will magically give you more golden walnuts! Keep doing this until you are absolutely swimming in golden walnuts. Then head over to Mr Qi’s store and swap those golden walnuts in for Qi Gems! It really is that easy… Just look at this, is this even fair? No of course not, this is a glitch after all.
8. Unlimited Free Money In Stardew Valley.

You can break the economics of the game by exploiting Sandy.
Did you know that you can take some money, and magically turn it into considerably more money?? It’s simple. Ensure that you have tons of kegs and the artisan profession. Then on a Friday, head over to sandies oasis. Buy as much honey as you can afford, the more the better. Then head home, and turn all of that honey into mead. The honey from sandies only costs 200 gold each. But when you turn it into Honey, you will make 420 gold. Effectively doubling your money instantly!!! The best part? It only takes half a day to turn honey into mead. This is truly broken.
9. Instant Max Animal Friendship Glitch.

This next glitch is more like an exploit and is incredibly disturbing… If you use this glitch, you’re sick! Anyway this glitch takes advantage of the lovely little animation canceling feature.
To cancel an animation simply hold down the shift, control and delete key while tapping the R key. It’s a little tedious if you do not remap these keys, however it’s ridiculously over powered if used correctly.
Now grab a milk pail and find yourself a brand new untouched cow or goat. Attempt to milk them and then cancel the animation. You won’t get any milk, but they will gain some friendship every time you do this! If you do it correctly, you can get a cow from zero hearts to maximum hearts in like ten minutes… This is ridiculous. It looks very sketchy, but it works,
10. Stardew Valley Raccoon Exploit.

A Brand new Glitch introduced in the latest 1.6 Update!!
You know that Racoon guy? This racoon guy! He wants various items and as you give them to him, he will get a family and his wife will start selling great items, yeah that guy. There is a very minor glitch with the quests he has. If he asked you for a very specific smoked fish, well apparently you can just give him any smoked fish and it’ll be accepted!
The same is true for pickled goods and juice. Just give him that type of item, even if it’s the wrong item, and there we go. This makes the quest quite easy doesn’t it. If you are not using this little glitch you are simply holding yourself back.
Bonus. Multiplayer Stardew Valley Exploits and Glitch

Multi player glitches,including table duplication and hitting an object duplication, building two buildings at the same time, and the second one was free
There was and still is this great glitch that allows you to duplicate anything. Just get another player, a very valuable item and a chair! Prismatic shards for example. Put the item on the table, and then both players just need to pick the item up at the same time. Now both players have a prismatic shard! Continue to do this to absolutely duplicate items with ease. Naturally if you both hit an ore node at the same time, both players will get the loot.

Okay check this out, if you and another player attempt to build a building at the same time, Robin will be more than willing to build both of the buildings at the same time! The timing doesn’t even need to be that good, this can help you rapidly get your farm up and running! Another glitch with robin is if you click on the upgrade and just hover there and wait, another player can spend all of your gold. Then click to confirm the building placement and there we go! You just got a building for free.
That wraps up our list of the most broken glitches and exploits in Stardew Valley.
