Randovania

Randovania is a free, open-source randomizer for supported games, available on Windows, macOS, and Linux. It can move weapons, keys, and other items among game locations, as well as alter area connections, travel requirements, starting equipment, and starting location. Its logic aims to keep randomized games completable without glitches or exploits. Multiworld sessions let items move across games and players, including a session played alone. Multiworld requires a Discord account, and integrations are listed for the Prime games, Cave Story, Metroid Dread, AM2R, and Samus Returns. There are no hard player or world limits, though sessions larger than 30 have had little testing. If the server connection drops, collected-item information is retained and sent when connection returns, including after a restart. Game files must be unmodified; Prime and Prime 2 require uncompressed GameCube ISO files. The Metroid Prime page specifies a GameCube ISO and either a modded Wii or Dolphin Emulator. Randovania is downloadable for free.

Randovania offers several ways to change supported games while aiming to preserve completable play. Check each game's file and setup requirements before starting, and contact the community on Discord about larger Multiworld sessions.

It suits players who want to customize supported games or set up multi-game sessions, alone or with others. Players should be comfortable preparing compatible, unmodified game files and using Discord for Multiworld.

Randovania is a free, open-source randomizer platform for players who want to rebuild progression in supported games without depending on glitches or exploits. It suits experienced players who value detailed run settings and group play, especially Multiworld sessions. The trade-off is a downloadable setup that depends on unmodified game files, and Multiworld also requires Discord.

Overview

Randovania’s central appeal is controlled unpredictability. Instead of merely raising difficulty, it rearranges the items and routes that determine how a game unfolds while trying to preserve a completable path. That makes it a strong choice for repeat playthroughs of supported titles and for communities organizing shared-item runs. It is a weaker fit if you want an instant, browser-based experience or do not have the required game files and hardware or emulator setup.

Key features

The randomizer can move weapons, keys, and other items between game locations. Its logic-focused approach aims to keep the resulting game finishable without glitches or exploits, so the challenge comes from adapting to altered progression rather than hunting for unintended shortcuts. This is more dependable for players who want a fair remix, though it cannot guarantee the same breadth of support across every game.

Randovania can also change area connections, travel requirements, starting equipment, and starting location. These are meaningful structural changes rather than cosmetic variations, giving experienced users substantial control over the shape of a run. The advanced customization level is a strength for repeat players, but it creates more decisions for newcomers than a narrowly scoped randomizer.

Multiworld distributes items across multiple games and players, and it can be used in a session played alone. That flexibility supports both solo experimentation and coordinated groups. A Discord account is required for Multiworld. The project credits Dolphin and Nintendont integrations for the Prime games and lists integrations for Cave Story, Metroid Dread, AM2R, and Samus Returns.

There are no hard player or world limits, but sessions above 30 players or worlds have had little testing. Larger groups should therefore involve the community on Discord before committing to an event. If the connection to Randovania’s server drops, collected-item information is retained and transmitted when the connection returns, including after a restart; that protects progress during longer sessions.

File compatibility is strict. Randovania supports only unmodified game files, and Prime and Prime 2 require uncompressed GameCube ISO files. The Metroid Prime setup specifically requires a GameCube ISO plus either a modded Wii or Dolphin Emulator.

Pricing

Randovania is free and open source. Its Free plan costs nothing and provides the downloadable randomizer platform, with the latest version recommended. There is no free trial because the software is already free, and there are no paid tiers or published seat quotas to weigh against the free offering. The practical cost is in preparing compatible, unmodified game files and, for Multiworld, maintaining a Discord account.

Platforms

The downloadable platform supports Windows, macOS, and Linux. Supported play environments extend to modded Wii and Wii U hardware, Nintendo Switch, Nintendo 3DS, and supported emulators. Compatibility is game-dependent, so a platform listed for Randovania does not remove the individual file and hardware requirements for a chosen title.

Who it's for

Choose Randovania if you replay supported games and want to control how thoroughly progression changes, or if you want item-sharing sessions that can connect several games and players. It is particularly well suited to communities comfortable with Discord and to players who can manage emulator or console preparation. Look elsewhere if you need a randomizer that works from ordinary, unmodified installs without ROM or ISO handling, or if you prefer a smaller set of preset choices.

Pros and cons

Pros

• Logic-aware randomization: item shuffling aims to preserve completable runs without glitches or exploits.
• Broad control: area links, travel requirements, starting gear, and starting location can all change.
• Flexible Multiworld: items can cross game and player boundaries, including solo sessions.
• Resilient reconnects: collected-item data survives disconnections and restarts.
• Open-source and free: the full downloadable platform costs nothing.

Cons

• Strict files: only unmodified game files are supported, with uncompressed ISOs required for Prime and Prime 2.
• Setup burden: Metroid Prime requires a GameCube ISO and a modded Wii or Dolphin Emulator.
• Discord dependency: Multiworld cannot be used without a Discord account.
• Large-session uncertainty: groups beyond 30 players or worlds have seen little testing.

Alternatives

Game Randomizer Tools is the broader starting point when you want to compare several randomizer projects.

Pick Ocarina of Time Randomizer instead for a free randomizer spanning Android, iOS, Linux, macOS, web, and Windows, provided you have an Ocarina of Time 1.0 NTSC-U or NTSC-J ROM.

Wind Waker Randomizer is the focused choice for a North American GameCube Wind Waker ISO and desktop play on Linux, macOS, or Windows.

Choose FF6 Beyond Chaos Randomizer for Final Fantasy VI/FF3 US 1.0 ROM randomization; non-Windows users also need Python 3.7 or newer.

The Wind Waker HD Randomizer is a free, MIT-licensed alternative dedicated to Wind Waker HD on Linux, macOS, and Windows.

Universal Pokémon Randomizer FVX is a downloadable desktop option for Linux, macOS, and Windows that uses user-supplied game ROM files.

Universal Pokémon Randomizer ZX is another free desktop Pokémon randomizer for those platforms, with source code under GPL-3.0.

Hollow Knight Randomizer 4 is the Windows-specific alternative for Hollow Knight 1.5+, but it requires the Modding API, MenuChanger, ItemChanger, RandomizerCore, and RandomizerCore.Json.

MultiworldGG is a free, open-source option with desktop releases for Linux, macOS, and Windows plus web access.

Verdict

Randovania is the right pick for players who want deep, logic-conscious remixing and Multiworld flexibility across supported games. Its main reason to choose it is the combination of advanced progression control, solo-capable item sharing, and reconnect protection at no cost. Look elsewhere if game-file preparation, Discord, or the uncertainty around very large sessions outweighs that control.
