Toggle every luck source you actually have stacked: Like, Group, Lucky Slime, Huge Lucky, gamepass, potions, rebirth. The math runs live, the expected hunt time updates as you flip switches — the all-in-one Slime RNG calculator for odds, jackpot chance and AFK hunt time.
1 / N is the per-roll odds. 8-hour figure assumes you stay AFK with current Roll Speed setting.
The calculator uses the same model shown in the FAQ: additive sources form the base, then multipliers stack on top. That means Like + Group create the base, while Lucky Slime, Huge Lucky, gamepass, potions and rebirth change the expected number of attempts. Roll speed does not change your odds — it only changes how fast you make those attempts, so it moves time-to-target, not the number of rolls you need.
Expected time is not a promise. Rare hunts use a geometric distribution, so two players with the same stack can have very different outcomes. The useful number is the confidence window: how much time you need before the odds become acceptable.
Like + Group is the baseline free stack. Use this to compare early targets before spending timed rewards from active codes.
After R1, the same code reward is worth more because the permanent multiplier compounds with temporary boosts.
For three-minute boosts, roll speed matters as much as luck because it decides how many attempts fit inside the timer.
×3 base luck. Lucky (1 in 21,500) is doable in 24 hours AFK with Roll Speed Boost active. Anything Divine-tier or rarer is statistically out of reach — focus on building your Mythic collection (Lucky, Stump, Lily, Crafty) and unlocking Lucky Slime’s ×3 passive before chasing rarer slimes.
Target picks: Lucky · Stump · Lily · Crafty
×16 effective luck (3 additive × 3 Lucky × 1.82 R1). Icy (1 in 86,100) and Orbit are reasonable 8-hour AFK targets. King Slime (1 in 538K Prismatic) becomes a multi-day grind without potions. Pop an Ultra Luck Potion + Huge Lucky for the highest 3-minute window.
Target picks: Icy · Orbit · Aegis · Wicked
×977 effective luck (3 × 9 × 6.03 × 3 × 2). Huge Icy (1 in 86.1M, divine-tier with ×1,000 Huge mutation) is reachable in roughly 4 minutes per hit. Prismatic to Transcendent base targets become feasible without the mutation multiplier piled on top. This is the “run the math” tier — use the calculator to see your AFK% before committing a 3-minute potion.
Target picks: Huge Icy · King · Pokey · Ninja
×4,000+ luck territory. Inverted variants (×2,500) become a coherent goal. Ethereal-tier slimes like Wizzy and Petal are reachable in long AFK sessions. Past R5, each additional rebirth doubles your reach; the question becomes how many goop cycles your patience can absorb, not whether the math allows it.
Target picks: Wizzy · Petal · Shelly · Inverted Huge variants
Like (+1) + Group (+1) = base 3. Each friend in the same server reportedly adds +0.5 (community report, not dev-confirmed). Additives apply before any multiplications.
Lucky Slime ×3 · Huge Lucky ×3 · 2× Server Luck gamepass ×2 · Luck Potion ×2 · Ultra Luck Potion ×3 · Rebirth multipliers ratchet ×1.82 per level. Same-class potions (Luck Boost vs Ultra Luck) are mutually exclusive; different classes (potion + dice + apple) multiply.
A slime with 1/100,000 base at multiplier ×100 becomes 1/1,000 effective. Doubling multiplier halves expected hunt time.
Source confidence is highest for documented drop rates and explicit multipliers. It is lower for community-reported roll speeds, friend bonuses and any target marked as an estimate. Estimated targets stay usable in the calculator, but they should not be treated as primary-sourced facts.
Known limitations: mutation dice are not modeled as permanent luck, display rounding may hide tiny differences at extreme multipliers, and server-side event boosts can change faster than static guide copy. When an event changes the math, check the Admin Abuse page and the latest code update first.
Stack everything multiplicative before you click Roll. A 2× Luck gamepass plus an Ultra Luck Potion plus a Huge Lucky aura is ×30, not the +30 your brain wants it to be. The math compounds, your patience does not.
