Source checked July 12, 2026. This order combines shared system facts with clearly labeled editorial priorities. ObbyList has not tested this route in game.
THE CURRENT ROUTE
Which Slime RNG upgrades to prioritize first
- 1
Unlock Auto-Roll first so rolls continue while you manage combat, zones, items, and other upgrades.
- 2
Open access tools next: Teleporter for returning to zones and Goop Drops for starting the Rebirth loop.
- 3
Add Slime Slots when your combat team is too small to clear enemies quickly.
- 4
Improve Coin Income when zone prices and new upgrades are taking too long to afford.
- 5
Increase enemy spawns after your team can clear them, creating more Coin and unlocked-loot opportunities.
- 6
Buy Luck upgrades when rarer rolls are the bottleneck, then use temporary boosts during active sessions.
- 7
Improve roll speed and milestone-roll branches when rolling volume, rather than combat, is slowing progress.
SOURCE CHECK
What we know
Official Roblox sources
- The official game description confirms rolling, upgrading Slimes, fighting enemies, unlocking worlds, and Luck as the main progression loop.
- The official page does not publish an Upgrade Tree, current prices, or an official best order.
Current supporting sources
- Game8 places Auto-Roll, Teleporter, Goop Drops, Slime Slots, and Diamond Rolls among its first major unlocks.
- Game8 progression guidance also supports Coin Income, more enemies, Luck, roll speed, Rebirth, and Slime levels as later priorities.
- Pro Game Guides independently confirms Luck branches, item-drop branches, enemy prerequisites, and Goop Drops inside the Upgrade Tree.
CHOOSE BY BOTTLENECK
Spend on the part of the loop that is actually slow
If enemies survive too long, improve the team before adding more enemy spawns. If Coins are slow, improve Coin Income and combat. If rolls are the problem, improve Luck, roll speed, and roll milestones.
This order is a conservative source-backed route, not an official or guaranteed best build. A strong roll can change which branch helps you most next.
SYSTEM UNLOCKS FIRST
Machines and new drops create new options
Teleporter, Goop Drops, item drops, Crafting access, and XP Transfer change the actions available to you. Unlocking a useful system often has more value than one small numerical increase.
DETAILS NOT YET CONFIRMED
Still checking
- Exact current prices and prerequisites for every Upgrade Tree node are not published because the accessible guides predate the July update.
- Diamond, Golden, Void, Clover, mutation, and later update branches may use different names or positions now.
- The Fandom Upgrade Tree links to a community image and interactive map, but it does not provide a dated text list that independently confirms every recommendation.
- No source proves one permanent best order for every roll, Rebirth level, or spending style.
