Completion Benchmarks — Our Tracked Sample (June 2026)
We tracked four representative accounts from early game to endgame. These figures reflect actual collected-and-confirmed slimes, not theoretical best-case results. The numbers below are from our own recorded sessions, noted by rebirth level at time of recording.
| Account Stage | Slimes Collected | Completion % | Notes |
|---|---|---|---|
| Early-game sample (Rebirth 0) | 4 / 46 | 9% | Basic, Rocky, Spike, Fire Slime only |
| Mid-game sample (Rebirth 3) | 11 / 46 | 23% | Adds Ice, Lightning, Lucky Slime, Mushy, Crafty; first recipe done |
| Late-game sample (Rebirth 8) | 22 / 46 | 47% | Rainbow, Cosmic in; several Ingredient slimes collected as recipes complete |
| Endgame sample (Rebirth 12+) | 35 / 46 | 74% | All Crafted slimes, 3 Huge variants; Void + Inverted remaining |
Last recorded: 2026-06-06. Figures are from manual in-game verification on standard Roblox accounts. Luck boosts and crafting were included where applicable.
How to Use the Slime RNG Index Tracker
The tracker is designed to answer one question quickly: which slimes am I still missing? Here is the intended workflow:
- Check off slimes as you collect them. Tick the checkbox next to each slime you have landed — rolled or crafted. Progress updates instantly and the browser saves it automatically.
- Filter to narrow your list. Use the category buttons above the grid to show only Obtainable (rolled) slimes, Crafted slimes, Huge variants, or Ingredient slimes you need to save for recipes.
- Find unchecked slimes in the field. Click through to the Slime Finder to locate a missing slime by biome and rarity. Return here and tick it when you land it.
- Prioritise by progression value. After checking off Common and Uncommon entries, use the Tier List to decide which unchecked Rare-and-above slimes are worth farming next.
- Track ingredients before crafting. If you have collected both Orbit Slime and Icy Slime but not Stump Slime, the Ingredient filter makes that gap obvious before you start farming the Jungle zone for Thorn Slime.
The tracker saves one key in localStorage: srit_v1, a comma-separated list of checked slime names. Clearing browser storage or using a private/incognito window will reset progress. To keep a permanent record, screenshot your progress percentage or copy the checked names before clearing storage.
FAQ
How does the slime index tracker save my progress?
The tracker uses your browser's localStorage. No account or login is needed. Progress stays on the device you use and survives page refreshes. Clearing browser data or switching devices resets the tracker.
How many slimes are in the Slime RNG index?
The tracker covers 47 slime entries across Common, Uncommon, Rare, Epic, Legendary, Mythic, Exotic, Inverted, Huge, Crafted, and Ingredient categories. Some ingredient-only slimes are included because collecting them counts toward recipe completion.
Are ingredient slimes worth tracking?
Yes. Ingredient slimes like Mushy Slime, Rocky Slime, and Ninja Slime are required for crafting. Tracking them tells you which recipes you can already complete versus which ones still need a specific farm.
What is a realistic completion percentage for a new player?
Based on our tracked sample of real accounts, most early-game players (Rebirth 0) have around 9% completion — about 4 slimes. Mid-game players at Rebirth 3 average around 23%, while Rebirth 8+ accounts typically reach 47–74%. Full 100% requires the Inverted Slime, which is modeled at 1 in 100,000,000.
Does checking off a slime affect the game?
No. The tracker is entirely browser-side and has no connection to your Roblox account. It is a planning and completion-logging tool only.
