Slime RNG Rarity Tiers
Slime RNG has 13 confirmed rarity tiers — from Basic to Celestial — plus 5 slime categories (Base, Big, Huge, Shiny, Inverted) that stack a multiplier on top. This guide lists every tier with documented base odds, example slimes, and when to target each tier based on your progress. Where official odds are not exposed we mark them needs_check rather than guess. Last checked 2026-06-23.
13 confirmed tiers
Basic → Common → Uncommon → Rare → Epic → Legendary → Mythic → Divine → Prismatic → Transcendent → Ethereal → Secret → Celestial/beyond.
Secret: ~1 in 1.07B
Single-source estimate (driffle.com June 2026). Not officially confirmed by Stouts Studio.
Epic (Orca)
Orca (~1 in 719) is the first documented mid-game farmer. Fill Uncommon/Rare slots first.
Mythic (Lucky) then Huge Lucky
Lucky slime gives roster luck at Mythic (~1 in 21.5K). Huge Lucky multiplies on top at massive odds.
All Slime RNG rarity tiers with base odds
Base odds apply to the Base slime category. Big slimes are ~100× rarer, Huge ~1,000×, Shiny ~250×, Inverted ~2,500× than the equivalent Base tier. Odds marked multi_source are confirmed by at least 2 independent third-party sources (driffle.com and TechWiser, both June 2026). Odds marked single_source are driffle.com estimates — treat as community-reported.

Slime categories: Base, Big, Huge, Shiny, Inverted
Rarity tier and slime category are two separate axes. A Huge Goopy is Basic rarity in the Huge category — which makes it ~1,000× rarer than Base Goopy, but still far easier than a Huge Legendary or Huge Prismatic. Total collection across all categories: approximately 500+ slimes.
| Category | Rarity multiplier vs Base | Description | Unlock requirement |
|---|---|---|---|
| Base | 1× | Standard form. Accessible from the start. | Default |
| Big | ~100× | Enlarged form. Requires Big Slimes upgrade. | Big Slimes upgrade |
| Huge | ~1,000× | Massive form. Requires Huge Slimes upgrade. | Huge Slimes upgrade |
| Shiny | ~250× | Luminescent visual variant. Requires Slimy Slimes upgrade. | Slimy Slimes upgrade |
| Inverted | ~2,500× | Color-inverted endgame variant. Requires Inverted Slimes upgrade. | Inverted Slimes upgrade |

Which Slime RNG rarity should you chase?
The table below maps your current situation to the right tier target. Rarity intent matters: a beginner chasing Mythic before stabilising Rare slimes wastes Luck Boost windows that would be worth 10× more at higher rebirth counts.
| Rarity tier | Your situation | Best action | Next page |
|---|---|---|---|
| Basic / Common | I just started and need any slime to clear the first zone. | Use as baseline only. Replace immediately when Uncommon slimes appear. | Beginner guide |
| Uncommon | I need early DPS before spending Luck Boost potions. | Fill all Uncommon slots before popping any Luck Boost from codes. | Slime RNG codes |
| Rare | I want the first real upgrade from starter slimes. | Target Buggy, Scorchy, Brutis, or Frankenslime for DPS. Auto Roll pays off here. | Roll speed |
| Epic | I want the first meaningful coin farmer or luck-adjacent slime. | Orca (~1/719) is the documented mid-game farmer. Stack permanent luck before grinding Epic. | Coins farming · Luck sources |
| Legendary | I want strong named slimes with solid DPS signals. | Rocky and Spidey appear at Legendary per 2026 sources. Target after Epic is stable. | Luck calculator |
| Mythic | I am chasing the Lucky slime for roster luck or end-game DPS. | Lucky (~1/21.5K) gives roster luck at Mythic. Stack rebirth multiplier, code boosts, and server luck before committing. | Rebirth guide · Server luck |
| Divine / Prismatic | I am a dedicated grinder targeting ultra-rare slimes. | Divine (~1/86K) and Prismatic (~1/538K) require a full permanent luck stack plus rebirth multiplier. Use the Luck Calculator to model your effective odds before grinding. | Luck calculator · Rebirth guide |
| Transcendent / Ethereal / Secret | I am hunting the rarest Base slimes documented in 2026. | Transcendent (~1/4.78M), Ethereal (~1/26.9M), Secret (~1/1.07B). Odds are single-source estimates. Stack every possible buff and be patient. | Huge slimes · Server luck |
| Huge / Shiny / Inverted | I am hunting trophy variants with category multipliers. | Huge is ~1000× rarer than Base equivalent. Shiny ~250×. Inverted ~2500×. Unlock the relevant upgrade first, then apply full luck stack. | Huge slimes guide |
Rarity hunting tips by tier
- Basic / Common slimes — your roster baseline. Replace as quickly as possible; never pop boosts here.
- Uncommon slimes — fill all Uncommon slots before spending any Luck Boost from codes. Target Meow and Glo (~1/35).
- Rare slimes (Buggy, Scorchy, ~1/103) — first meaningful DPS gate. Auto Roll and coin route should be stable here.
- Epic slimes (Orca, ~1/719) — payoff zone for stacked Luck Boost code rewards. Coins farming starts here.
- Legendary slimes (Rocky, Spidey, ~1/4.27K) — strong collector tier. Worth targeting with permanent luck stack and rebirth multiplier.
- Mythic slimes (Lucky, ~1/21.5K) — roll under Ultra Luck Boost only. Stack every luck source and use server luck before committing.
- Divine / Prismatic (1/86K – 1/538K) — dedicated grinder territory. Full stack: rebirth multiplier + permanent luck + server luck x256 + Luck Boost.
- Transcendent / Ethereal / Secret (1/4.78M – 1/1.07B) — long-term trophy hunts. Odds are single-source estimates. Huge slime guide applies similar stacking logic.
