Build A Ring Farm has released Update 4, bringing in 24 new plants, a 4th Floor, Plant Contracts, a Farm Skins System, and 4 new mutations. This is one of the game’s biggest updates so far, but the real question for most players is simple: what should you do first once the patch is live?
The best opening route is still practical rather than flashy. Redeem the current codes, check whether Floor 4 is open for you, look at Farm Skins before spending, and only then test contracts or new plants selectively. That framing matters, because this page is most useful when it helps you sort priorities instead of just repeating the patch list.
What’s new in Update 4
According to the current Update 4 summary, this patch includes:
- 24 new plants
- 4th Floor
- Plant Contracts
- Farm Skins System
- 4 new mutations
- QOL improvements and bug fixes
This patch touches almost every layer of the game at once — your plant pool, your floor progression, your equipment, your farm appearance, and your mutation options. That makes it more than just a routine content refresh.
Patch breakdown
1. 24 New Plants — more options, but don’t rush a full rebuild
“24 new plants” is the biggest headline number in Update 4, and it is certainly a large expansion to the plant pool. But a bigger pool does not mean every player should immediately tear up their current layout.
On patch day, the smart approach is to treat these as new progression branches rather than automatic upgrades. Until the full list is better mapped, test selectively: try a few new plants on an open plot, compare them against what you already run, and only commit to a broader swap if you see clear improvement.

2. 4th Floor — the next progression milestone
The addition of a 4th Floor is one of the most structurally significant changes in Update 4. For players who have already unlocked floors 1 through 3, this opens up a new tier of farm real estate, which usually means more room for cash crops, new plant layouts, and higher-end farm optimization.
If you are still working on earlier floors, Floor 4 is a long-term target rather than an immediate concern. But if you are already at midgame or beyond, this is likely where you want to focus your early patch energy — new floors tend to reward progression investment more reliably than experimental systems on day one.
For overall progression help, see Build A Ring Farm Progression Guide.
3. Plant Contracts — a new system worth watching
Plant Contracts are introduced in Update 4 as a new gameplay layer. While the exact rules, reward structure, and long-term value are not yet fully documented, the concept is clear: contracts give you targeted planting goals with specific payouts.
The editorial take here is cautious. Contracts could become a major part of the daily or weekly farm loop, but on day one they are harder to evaluate than floor expansion or skin bonuses. The safest approach is to test a contract when you see one, compare the reward against the opportunity cost, and avoid locking your farm into contract-only mode until you have a feel for the math.
4. Farm Skins System — the most immediately useful new feature
The Farm Skins System is arguably the most valuable addition in Update 4 for active players. Unlike purely cosmetic systems in many games, Farm Skins in Build A Ring Farm come with permanent stat bonuses that apply regardless of which plants you run or what floor you are on.
The screenshot above shows the Farm Skins selection screen. What matters here is that skins are not just visual flair — they unlock stat boosts that stay active as long as the skin is equipped. That makes them one of the few upgrades in the game that give you permanent, loadout-independent value.
For active players, the practical takeaway is:
- Check the skin list early, even if you are not sure you want to buy one yet
- Skins with clearly shown cash or farm earnings bonuses are likely the safest first pick
- Do not assume the most expensive skin is the best value — compare bonuses per cost
For the full breakdown of available skins, bonuses, and unlock requirements, see the dedicated Build A Ring Farm Farm Skins Guide.
5. 4 New Mutations — expansion to an existing system
Update 4 adds 4 new mutations to the mutation pool. Mutations already sit close to some of the game’s highest-value decision making, so even a modest expansion is worth noting.
The editorial caution here is the same as for new plants: until the full list and specific effects are publicly documented, it is better to treat these as additions to explore rather than must-have upgrades. One or two of them may shift the meta, but the safe move is to evaluate them against your current mutation setup before chasing the new ones.

What should you do first after Update 4?
If you are jumping into the patch and want the cleanest route, this is the order I recommend.
First: redeem the current codes
This is still the easiest first step in any update.
The site’s current verified codes page always has the latest working codes. Even if you do nothing else right away, codes are the fastest low-risk boost available.
Start here: Build A Ring Farm Codes
Second: check your Floor 4 access
If you already have floors 1 through 3 unlocked, check whether Floor 4 is accessible and what the unlock requirements are. Floor progression is usually the most reliable long-term investment in the game, so this should be one of your first real commitments.
Third: look at Farm Skins before spending
Before you spend currency on new plants, contracts, or mutations, open the Farm Skins menu and see what is available. Skins give permanent bonuses that do not compete with your farm layout. That makes them one of the highest-return first purchases in this patch — especially if your current farm is already running smoothly.
Fourth: test Plant Contracts and new plants selectively
Once your floor access and skin situation are clearer, move on to testing. Try a single Plant Contract to understand the reward structure. Add one or two new plants to an open plot and compare their performance. Do not commit your whole farm to untested systems on day one.
Fifth: revisit mutations after you have a stable patch baseline
The 4 new mutations are worth your attention, but they are unlikely to be the most urgent thing on day one. Get your floor, skins, and a test contract done first, then check whether any of the new mutations change your existing mutation strategy.
Sixth: fall back on clean progression if needed
If your farm basics are still shaky, this patch is not a reason to skip the fundamentals. Stable harvesting, smart upgrade timing, and controlled spending still matter more than sampling every new feature at once.
If you need a cleaner fallback route, use Build A Ring Farm Beginner Guide.
What’s confirmed and what still needs tracking
Confirmed from the current update summary
- 24 new plants
- 4th Floor
- Plant Contracts system
- Farm Skins System with stat bonuses
- 4 new mutations
- QOL changes and bug fixes
Still worth tracking in follow-up coverage
- the full list of the 24 new plants
- the full list of the 4 new mutations
- Plant Contracts reward structure and optimal routes
- which Farm Skins offer the best value per bonus
- the exact unlock requirements for Floor 4
- whether any new plants or mutations immediately outperform established options
That is why this post is written as a log plus editorial guide, not as a pretend all-in-one database on day one.

In short
Update 4 gives Build A Ring Farm its biggest feature drop yet. The Farm Skins System and 4th Floor are the parts most likely to change how active players prioritize their time, while Plant Contracts and the expanded plant and mutation pools add depth that will unfold over the first few weeks.
If you only remember one line, make it this: redeem the codes first, check Floor 4, evaluate Farm Skins before spending, then explore contracts and new plants selectively instead of chasing everything at once.
