Auto Roll
Buy firstThis is the real start of automation. Rolls keep accumulating while you farm, so every later upgrade arrives sooner.
Beginner guide
Slime RNG Upgrade Priority Guide
The upgrade tree looks broad, but the early game is not. Build automation first, then movement, then the systems that multiply coins, Rebirth progress, and rare-roll consistency.
Start with these 5 upgrades
If you only want the short version, follow this order. It covers automation, travel, Rebirth setup, damage output, and rare-roll protection before you start spending wide.
Teleporter
Buy earlyIt feels optional at first, but fast travel becomes a major time saver once zones and crafting routes spread out. It sits in the Player tree, where new players often forget to look.
Goop Drops
Set up RebirthYou do not need Goop immediately, but unlocking drops early lets future Rebirth progress build in the background.
Slime Slots
Add damageMore active slimes mean faster kills, more coins, and less time wasted in every later zone.
Diamond Rolls
Add safetyDiamond Rolls act as a rare-slime pity system and use a separate counter from Golden Rolls.
Why Auto Roll is first
Rolls are not only slime attempts. They also feed later upgrade spending, so every second before Auto Roll is lost background progress.
Do not confuse pity counters
Golden Rolls and Diamond Rolls are separate systems. Triggering one does not reset the other, so Diamond Rolls remain useful even after a Golden payout.
Where each priority starts paying back
Auto Roll
Starts paying back immediately because rolls keep generating while you do everything else.
Teleporter
Feels modest early, then becomes essential once travel between unlocked zones starts wasting real time.
Goop Drops
Does little the moment you buy it, but passively prepares the Rebirth loop while you keep progressing.
Slime Slots
Turns into visible coin speed because more deployed slimes clear enemies faster.
After the core unlocks, build the coin engine
Coin Income
The cleanest return after your core unlocks. Every kill immediately pays more.
More Enemies
More targets increase coin flow, and later enemy variants pay out even better.
Roll Speed
Faster rolls increase both slime acquisition and the roll currency used by other upgrades.
Luck
Luck improves rare-roll odds, but it pays back best once your roll volume is already high.
If your first purchases feel slow, collect active Slime RNG codes before the next session. Once you are comparing Luck against more roll volume, use the calculator instead of guessing which one shortens your current target more.
Once Potions are unlocked in the Loot tree, enemies can also drop temporary Luck, Roll Speed, Currency, and Ultra Luck boosts. Active farming then supports both your permanent economy and your short farming windows.
Before Rebirth
Push well into the current run before resetting. Food is also worth using beforehand because slime levels carry over and help the next run clear early enemies faster.
When crafting starts
Crafting opens in Heaven, the seventh zone. Teleporter becomes much more valuable here because recipe routes and zone movement stop being trivial. Once you begin collecting recipe scrolls, crafted slimes can become stronger than what you would naturally roll at the same point in progression.
How the three upgrade branches fit together
General tree
Enemy count and combat-facing unlocks live here. This branch controls how many targets you can turn into coins.
Loot tree
Coin Income, Food, and Potions live here. This branch improves what each fight gives back.
Player tree
Teleporter and player utility upgrades live here. This branch saves time and reduces run friction.
Upgrade tree quick reference
Use this as the readable version of the upgrade tree while planning a run. It groups the same systems from the guide into the branches players actually need to think about during progression.
| Branch | Key upgrades | What it changes |
|---|---|---|
| General | More Enemies, Big/Shiny/Huge enemy unlocks | Raises target count and improves raw coin throughput. |
| Loot | Coin Income, Food, Potions | Improves rewards per kill and unlocks growth items. |
| Player | Teleporter | Cuts travel time and supports crafting routes. |
| Roll systems | Auto Roll, Roll Speed, Golden Rolls, Diamond Rolls, Luck | Controls volume, pity systems, and rare-roll quality. |
