Upgrade Priority
| Priority | Upgrade lane | Why it matters |
|---|---|---|
| 1 | Auto Roll or automation | More rolls with less friction |
| 2 | Roll speed | More attempts during each boost window |
| 3 | Basic luck support | Helps once you can actually roll often |
| 4 | World unlocks | Opens new targets when current progress slows |
| 5 | Crafting and materials | Useful after requirements are clear |
| 6 | Cosmetic or side purchases | Save for later unless they unlock real progress |
Spend Decision Table
| You are blocked by… | Spend on | Wait on |
|---|---|---|
| Too much clicking | Auto Roll or automation | Rare hunting |
| Boosts ending with few rolls | Roll speed | More weak potions |
| Same low-value results | World unlock or luck support | Cosmetic spending |
| Unknown recipe requirement | Hold materials | Random crafting |
| Rare roll confusion | Record the result | Blind trading or selling |
First Three Purchases
- The first purchase should make rolling easier.
- The second should increase roll pace or session efficiency.
- The third should answer the next blocker: world access, luck, or a required material path.
If a purchase does not help you roll more, roll better, or unlock the next clear area, it can probably wait.
When To Unlock Worlds
Unlocking a new world is useful when the current world no longer gives practical progress, but switching too early can waste boosts. Before moving, check:
| Check | Good sign |
|---|---|
| Current-world progress | Rolls feel capped or repeated without useful upgrades |
| Required materials | The next upgrade points to a new area |
| Enemy slime pressure | You need stronger targets or rewards |
| Boost timing | You are not wasting an active timed boost while traveling |
Material Hold Rule
Apples and other materials should stay in your inventory until you know what they unlock. A weak early spend can delay a stronger crafting step later.
| Material situation | Best action |
|---|---|
| You know the exact recipe | Spend if it fixes your bottleneck |
| You only saw the item in a code reward | Hold |
| A friend says it is valuable | Ask what current upgrade uses it |
| You need coins more than materials | Do not trade unless replacement is easy |

FAQ
What should I upgrade first in Slime RNG?
Upgrade toward Auto Roll or the nearest automation feature first because repeated rolling is the main progress engine.
Is roll speed better than luck?
Roll speed is often better early because it improves every session. Luck is strongest once you can roll continuously.
When should I unlock a new world?
Unlock a world when your current world stops giving useful progress or when a quest, enemy slime, or material need points there.
Should I spend apples and materials early?
Hold materials until the upgrade or crafting requirement is clear. Spending them blind can block a better route.
