Rolls/Open Case Roblox Studio System

Gacha & RNG Crate System — by Nabi Studios

A complete, ready-to-integrate Gacha/RNG system for Roblox, built for games that want a polished, addictive collection loop — the kind players keep coming back for.

7-Tier Rarity System

Common, Uncommon, Rare, Epic, Legendary, Mythical, and Divine — each with its own color identity and gradient styling, tuned for a smooth, satisfying progression from your first roll to your rarest pull.

5 Unique Mutations

Gold, Zombie, Lightning, Blackhole, and Rainbow — each mutation carries its own value multiplier and a custom animated gradient effect that makes mutated items instantly stand out in your inventory and results screen.

Cinematic Roll Experience

A conveyor-belt style roll animation with fisheye zoom, camera shake, screen blur, tick sounds, and a winner-flash effect. Includes both 1x and 10x roll modes, plus a Skip Animation toggle for players who want to roll fast.

Full Result & Reward Display

Single-pull and batch (10x) result screens with confetti bursts, glowing mutation effects, and dynamic odds display — showing exact drop chances per item, factoring in rarity, item multiplier, and mutation.

Inventory & Backpack System

A persistent backpack with rarity filters, a favorite system, single-sell and sell-all functions, and animated slot rendering — capped and fully synced between server and client.

Dual Currency Economy

Built-in Cash and Key systems, with a shop supporting both Robux and in-game currency purchases.

Polished UI Throughout

Every button, panel, and menu features smooth hover/click animations, open/close transitions, and integrated sound design — no stiff, static UI anywhere in the system.

Cinematic Crate Intro

A dedicated cinematic camera sequence plays when players interact with crates, giving the whole experience a premium, game-studio feel.

Built entirely in Lua/Luau with clean, modular architecture (server-authoritative rolls, RemoteEvents, ModuleScripts) — easy to plug into your existing game.
