If you're grinding away in Build an Ant Empire and wondering which upgrades to buy first, you're not alone — the upgrade boards can be overwhelming for new players. Knowing the best upgrades Build an Ant Empire offers is the difference between a slow crawl and explosive colony growth, because every Cash you spend should compound into more income. In this guide, we rank every upgrade category, explain the optimal purchase order, and share spending strategies that helped community players scale from a single Common ant to colonies generating billions in Cash.
How Upgrades Work in Build an Ant Empire
Before diving into the tier list, it helps to understand the core loop. You hatch ants by purchasing eggs from the Ant Queen, place them into colony slots, and they produce boxes of food. Selling those boxes at the Sell station earns you Cash — the currency that fuels every upgrade you'll ever buy.
Every upgrade category you purchase increases in price with each level, creating a deliberate cost escalation. This means indiscriminate spending will stall your progress fast. The Build an Ant Empire best upgrades strategy isn't about buying everything evenly — it's about sequencing purchases so each one multiplies your income potential.
The main upgrade categories you'll find at the upgrade boards include:
- Colony Expansion – adds more ant slots
- Food Value – increases Cash earned per food box sold
- Ant Speed – ants produce food faster
- Egg Luck – improves odds of rolling rare ants
- Egg Rolls – increases the number of rolls available
Best Upgrades in Build an Ant Empire: Tier List
Based on the game's mechanics and community consensus, here's how the upgrade categories stack up.
| Tier | Upgrade | Why It Ranks Here |
|---|---|---|
| S | Egg Luck | Unlocks high-rarity ants that massively boost food value; among the cheapest upgrades early on |
| S | Egg Rolls | More rolls means more chances at rare and Mutated ants per visit to the Queen |
| A | Colony Expansion | More slots = more simultaneous producers, but slot costs climb steeply |
| A | Food Value | Directly multiplies Cash per sale; strong once you have quality ants filling slots |
| B | Ant Speed | Solid boost, but speed means little if your ants produce low-value food |
| B | Items (Potions) | Expensive; save the best Potions for your top-tier ants only |
The key insight: egg-related upgrades (Luck and Rolls) are typically the cheapest available, which makes them ideal for bulk purchases early on. According to player experience, prioritizing these two categories in the first hour of play dramatically accelerates progress compared to dumping Cash into colony space.
The Optimal Purchase Order (Step by Step)
Here's a practical spending sequence that works for most players, whether you're starting fresh or resetting your strategy.
| Step | Action | Reasoning |
|---|---|---|
| 1 | Buy 2–3 levels of Egg Luck | Cheapest rarity boost available; sets up quality rolls |
| 2 | Add Egg Roll upgrades | Maximizes each Queen visit's value |
| 3 | Save Cash to actually purchase eggs | Rolls are free, but the ants themselves cost Cash — don't go broke |
| 4 | Buy rare or Mutated ants on sight | Rarity is the fastest gauge of production efficiency |
| 5 | Expand colony slots as Cash allows | Fill new slots only with your best ants |
| 6 | Alternate Food Value and Ant Speed | Multiplies income once your roster is strong |
| 7 | Consider Potions last | Apply Mutations manually to your most valuable ants |
A common beginner mistake is spending every Cash the moment it arrives. Because upgrade prices escalate with each purchase, you should always keep a reserve so you never have to skip a high-rarity ant that appears at the Queen's podium.
Why Egg Luck and Egg Rolls Beat Everything Else Early
Your ants determine the value of the food they produce — not the upgrades themselves. This is why the S-tier upgrades are the ones that improve ant quality rather than ant quantity. A single Legendary ant can outproduce several Common ants, and Mutations stack additional efficiency multipliers on top of rarity.
| Upgrade Focus | Early Game Result | Late Game Result |
|---|---|---|
| Egg Luck + Rolls first | Faster access to rare ants, Mutations | Compounding income from elite roster |
| Colony slots first | Many slots, but weak producers | High slot costs with low per-ant output |
| Food Value first | Higher Cash per weak box | Diminishing returns without quality ants |
Since egg upgrades are also the least expensive on the boards, you can buy them repeatedly without draining your wallet. By contrast, Potions in the Item Shop are prohibitively expensive for newer players — treat items as a secondary priority at best until your base upgrades are well established.
Free Resources That Accelerate Upgrade Purchases
Upgrades cost Cash, and Cash comes from selling food, so anything that boosts your economy helps you buy upgrades faster. The Index is an underused feature: every time you discover a certain number of new ants or Mutations, milestone rewards become claimable. These are one-time freebies, but early on they can fund several upgrade levels for free.
Mounts, on the other hand, are a trap for upgrade-focused players. Turning an ant over to the mount training NPC removes it from your colony permanently — win or lose the training roll. Since the teleport button gets you back to your nest instantly anyway, most experienced players skip mounts entirely.
| Resource | Benefit | Best Used When |
|---|---|---|
| Index rewards | One-time Cash and item freebies | Claimed as soon as milestones unlock |
| Mutations | Multiplies ant efficiency | Applied to your highest-rarity ants |
| Potions | Manually adds Mutations | Reserved for top producers only |
| Mounts | Slightly faster walking | Skippable — costs you a colony ant |
Finally, a word of caution for players researching this game: some guides and code lists online cover a similarly named experience ("Ants Empire"), which is a separate Roblox game with different mechanics like Sugar, Gold Leaf, and Queen quests. Make sure any codes or tips you find actually apply to Build an Ant Empire before using them. For general Roblox guidance, the official Roblox support site is the most reliable reference for account and platform questions.
Late-Game Upgrade Strategy
Once your colony is populated with high-rarity, Mutated ants, the math changes. At this stage:
- Food Value upgrades become your best friend, multiplying the already-huge output of elite ants
- Colony Expansion justifies its steep costs because every new slot holds a money-printing ant
- Ant Speed catches up in value since faster production cycles on expensive ants compound quickly
- Keep a trickle of Egg Luck levels going to chase rarer discoveries for Index milestones
The end goal per community reports is an empire generating billions of Cash per sale cycle — achievable only when upgrade purchases follow this compounding order rather than being bought at random.
