Gacha System — Lottery & Loot Plugin for RPG Maker MZ

Gacha System for RPG Maker MZ

Add a fully-featured gacha lottery to your game — draw prizes straight from your database (Items, Weapons, Armors, and Characters) and turn premium currency into your most compelling reward loop. Configure everything in the Plugin Manager; no scripting required.

Features

• Multiple banners/pools, each with its own cost, prize list, and rules
• Rarity tiers with transparent, adjustable pull rates
• Pity system — guarantee a top-rarity prize within X pulls so players never feel cheated
• Multi-pull (x10) with a guaranteed minimum rarity
• Duplicate conversion — unique prizes (like characters) turn dupes into currency instead of dead pulls
• Built-in pull screen with a live rates display, or drive it all from events for your own custom presentation
• Premium currency stored in a Game Variable — sell it in a shop, grant it as a reward, your call
• Saves and loads pity progress automatically

FAQ section

Q: Which engine does this work with? RPG Maker MZ. It works for desktop, mobile, and web deployment.

Q: Do I need to know JavaScript to use it? No. Everything is configured in the Plugin Manager — pools, rarities, rates, costs, and prizes. You open the gacha with a plugin command. Script calls exist for advanced users but aren't required.

Q: What can be given as a prize? Anything in your database — Items, Weapons, Armors, and Actors (recruitable characters). Each prize points at one database ID and belongs to a rarity you define.

Q: What is the premium currency? Can I sell it for real money? The currency is stored in a Game Variable (e.g. "Gems"), so it's in-game currency. The plugin does not process real-money payments and is not a real-money gambling system. You grant currency however you like — a shop, a quest reward, or the Add Currency command. If you want real-money purchases, that's a separate storefront/payment integration you'd handle yourself.

Q: Does it have a pity system? Yes. Each pool can guarantee a chosen rarity (or better) within a set number of pulls, and the counter resets when the player lands it. Pity progress is saved with the game. Set it to 0 to turn it off.

Q: Can I have multiple banners? Yes — create as many pools as you want, each with its own cost, prize list, rates, pity rule, and multi-pull guarantee.

Q: What happens when a player pulls a character they already have? Mark that prize "Unique" and duplicates automatically convert into premium currency (an amount you set per rarity) instead of stacking a useless copy.

Q: Are the pull rates shown to players? Yes. The built-in pull screen includes a "View Rates" display so odds are transparent — good practice, and expected (or required) in some regions.

Q: Can I use my own UI instead of the built-in screen? Yes. Use the "Pull (no scene)" command, which deducts currency, awards prizes, and flips a switch for success/fail. Branch on that switch to drive your own pictures, animations, and messages.

Q: Will it conflict with my other plugins? It stores pity on the save system and uses a Game Variable for currency, so there are no known conflicts with common menu or core plugins. Place it below core/engine plugins in the list.

Q: Can I use this in a commercial game? Yes — free for commercial and non-commercial projects, and you may edit it to fit your game. You just can't resell the plugin itself. Credit is appreciated but not required.

Q: Was AI used to make this? Yes — the plugin code was scaffolded with AI assistance, then reviewed and tested before release.
