Build A Ring Farm Update 4 is the biggest content drop the game has seen, adding a wave of new plants, mutations and pets. Because the game is updated so frequently, much of the data is still being confirmed in-game — so this rundown sticks to what multiple sources agree on and labels the rest as community-reported. For where these additions fit into your farm, pair this with how to make money fast.
What’s new at a glance
According to Pro Game Guides, Update 4 introduced 24 new plants and four new mutations — Admin, Fire, Bubblegum and Starfall — alongside new pets. That is a huge expansion to both the seed pool and the multiplier ceiling, and it reshuffles what the strongest farm setups look like.
The four new mutations
Mutations are the biggest single multiplier on a crop, and Update 4 pushed the ceiling higher:
- Fire — reported at a 10× income multiplier, the highest figure currently circulating.
- Cosmic — reported at 8×, a spray-only mutation.
- Bubblegum — a new event/spray mutation added this update.
- Admin and Starfall — special mutations, with Starfall tied to a specific new pet (see below).
A quick caution: the exact Fire and Cosmic multipliers are community-reported and contested between sources, so treat the 10× and 8× figures as leads until they’re confirmed. You can see the full list of values, event chances and spray costs on the mutations page, or compare them on the best mutations ranking.
New plants
Update 4’s 24 new plants stretch the seed roster across the rarity tiers, giving both early and late-game farms fresh options. The headline picks are the high base-income crops at the top end, which pair best with the Outer ring and a strong mutation. As exact costs, grow times and roll odds get verified, they’re added to our seeds database and ranked by value per second on the best seeds tier list.
New pets, including the Starfall Griffin
Update 4 also expanded the pet pool. The standout is the Starfall Griffin, a Divine-rarity pet that applies the new Starfall mutation automatically — multiple guides now rank it as the best pet in the game. If you’re deciding which companions to chase, our best pets tier list breaks down where the Update 4 pets land against established favourites like T-Rex and Kitsune.
What this means for your farm
The practical takeaway from Update 4 is that the income ceiling moved up. Fire and Cosmic raise how high a single harvest can spike, the Starfall Griffin automates a top-tier mutation, and the new high-rarity plants give the Outer ring better tenants. None of that changes the fundamentals, though: keep plots full, climb the seed tiers, use the rings, and reinvest into the Saw. Update 4 simply adds new top-end targets once your base loop is running.
How the new mutations shift the meta
Before Update 4, Rainbow (5×) and Honeycomb (6.5×) were the top of the mutation ladder. Update 4’s reported Cosmic (8×) and Fire (10×) sit above both, which changes the maths on your best harvests: a crop that previously capped at a 6.5× Honeycomb can now, in theory, hit 10× with Fire. On a high base-income seed sitting on the Outer ring (19×), that jump from 6.5× to 10× is an enormous swing in a single harvest’s value. The trade-off is access — the strongest mutations are spray-only or tied to rare events and pets, so they cost real in-game resources to apply. As always, save them for your highest base-income crops rather than spreading them thin.
Should you grind Update 4 content now?
If your farm is still early, the honest answer is no — the new top-end plants and mutations are late-game targets, and chasing them before your base loop is solid will stall your progress. Build a stable farm first: keep plots full, climb to Epic and Legendary seeds, and max your Saw. Once you’re comfortably earning and have spare cash, then start chasing Update 4’s high-rarity plants, the Starfall Griffin pet, and Fire or Cosmic sprays. The update raised the ceiling, but the floor — a full farm with a strong loop — is still where the money is built.
Update 4 codes
New updates almost always come with fresh codes, and Update 4 was no exception — milestone and update codes like 250KUSERS (a Time Skip) and UPDATE2 (a Tropical Seed Pack) are tied to the game’s growth and patches. These are the fastest way to sample new content without grinding for it first. Codes are case-sensitive and expire, so check the current working list on our codes page and redeem them before they rotate out. It’s worth rechecking right after any update drops, since that’s when new codes tend to appear.
How to get the new content
Most new plants come through the usual routes — the Seed Roll, Seed Packs and the Seed Collector — while new pets come from eggs at the Egg Shop. The fastest free head start is still codes: redeeming an active code for a Tropical Seed Pack or fertilizer gets you into the new content sooner. New codes also tend to drop alongside updates, so it’s worth rechecking the codes page after every patch.
Staying current
Build A Ring Farm patches arrive quickly, and reported values shift between them — which is exactly why we label every figure by source and recheck after updates. If you’re new to the game, the beginner’s guide covers the fundamentals that don’t change patch to patch, and the calculator lets you test any of Update 4’s new seeds and mutations against your current setup before you commit.
