What is the Index?
Press Index on the left side of the lobby (the blue notebook). It opens a spiral notebook with a row of tabs at the top, a big percentage for the current tab, a list of the words you have found, a progress line with a reward, “Total” at the bottom left and page arrows at the bottom right. On a brand-new account every tab says 0% and the pages are empty.
The 10 Index categories
| Tab | What goes in it |
|---|---|
| 🗡️ Weapons | Guns, blades and explosives that drop for players to use. |
| 💀 Monsters | Creatures and characters that hunt players. |
| 🐾 Animals | Real and prehistoric animals, from dinosaurs to sharks. |
| 🌳 Nature | Terrain and landscape changes to the island. |
| 🌧️ Weather | Sky, light and weather effects. |
| 🌪️ Disasters | Map-wide hazards like tsunamis, tornadoes and nukes. |
| 🏰 Places | Buildings and whole locations that appear on the island. |
| 🍔 Food | Food that spawns on the map, some of it healing. |
| 🛋️ Objects | Props, vehicles and tools. |
| ✨ Memes & Powers | Memes, characters and superpowers. |
Words we have confirmed in our own Index: dragon (Monsters), snow and horror (Weather) and luffy (Memes & Powers).
Which words count?
- Words you write count. A “+1 word” message pops up when you write a word that is new to your Index (we saw it for DRAGON, HORROR and LUFFY).
- Words other players write do not. After our first match, with more than a dozen words on the map, the Index only had our two.
- Auto-written words count. When our timer ran out the game wrote SNOW for us, and snow was in the Index afterward.
- Loading-screen words did not. MEDKIT and KATANA written for us during loading did not show up.
Each entry has a short description and a counter, for example “dragon — A dragon breathes fire — x1” and “luffy — Rubber arm stretches and slings — x1”.
Reading the percentages
Each tab shows the share of that category you have found. Our numbers after two matches: Monsters 2% (1 word), Weather 6% with snow alone, then 12% with snow and horror, and Memes & Powers 1% (1 word). The total stayed at 1% with four words. That tells you the categories are very different in size: one Weather word is 6%, but one Memes & Powers word is only 1%, so Weather is a small category and Memes & Powers a big one. The total is several hundred words, far more than the 150 needed for Collector.
The Collector badge
“Discover 150 words in your Word Diary.” It is one of the rarest badges: 1,077 owners when we checked, compared with millions for the easy badges. Because only your own words count, you need around 150 writing turns with a different word each time. Your writer chance in a match is low at the start (8% for us) and grows as players drop out, so plan on many matches.
How to fill the Index faster
- Never repeat a word when you are going for the Index. Keep a list of what you have written.
- Target small categories first for quick percentage wins: Weather filled fastest for us.
- Use the word list on this site for ideas; every word there is one we have seen work.
- Buy x2 Chance or Write Next only if you really want to speed up; both are Robux products.
- Write quickly. If the timer runs out the game picks the word, which may be one you already have.
- Remember the rules: a second NUKE becomes bombs and filtered words lose your turn (see word rules).
