Play The Origin Read the Rules

Getting Started

To start the game, the host should tap on "host game," login if they have not logged in already, enter what they want to be called in-game, and tap "create game."

After a game lobby is created, as many as 50 people may join using the game key at the top of the host's screen. The host may modify the game with optional roles, and then tap "start game."

When the game starts, your role card will be shown. In a basic game, you will be either a Researcher (the "good guys") or The Origin (the basic Infected Master, found in every game).

IF THIS IS YOUR FIRST GAME
    L90 is a chaotic and loud game, which can make your first game hectic and a little difficult. To make it a little easier, we recommend using the first game as an opportunity to learn and focus on the interface on your phone. Get comfortable with sending and analyzing the samples, conducting tests, and using your clue card. If you are playing with someone who has played before, don't be afraid to ask them for help! They want you to have a good time (even if they are on the other team). 

    Fortunately, games are only 10 minutes long at max, so once you've gotten comfortable with the controls, you'll be able to jump into a second game right away and focus more on the group and the strategy. During your second game, try to piece together the clues and figure out who you can trust. 

    By the end of this second game, you should feel like a pro.

FIRST GAME RECOMMENDED SETUP

6-7 players: 1 Minion and 1 Origin

8-12 Players: 1 Origin and 1 Corruptor

13+ Players: 1 Origin, 1 Corruptor, and 1 Minion

Playing as a Researcher

Team: Researchers (duh)
Abilities: Send and analyze samples. Perform tests.

The goal is to find the other Researchers and pool your information with theirs. Collectively, you will find The Origin and any other Infected Masters.The Researchers have nothing to hide, so feel free to yell out any and all information you discover.

SEND SAMPLES
    When the game starts, you will have a sample generated that you can send right away and a choice of a limited number of players to send it to. Send it to the person that you trust the most. After you do, you will isolate a new biological sample every 30 seconds. Sending samples is always safe, but you'll still want to send it to a Researcher since they are the ones you can trust.

ANALYZE SAMPLES
    You will receive samples from other players throughout the game. If you receive a sample from someone you believe to be a Researcher, you should probably analyze it. If it is from a Researcher, the analysis will tell you true information about the game... maybe enough to determine who the Infected Masters are! However, if the sample is from The Origin, (or any Infected player who can infect you, such as a promoted Minion), you will become infected. Because of this, you should discard samples that you suspect are from the Infected team.

SHARE INFORMATION AND LISTEN
    Whenever you get a noninfectious sample, you should share this information with the rest of the group. Remember, you have nothing to lose by sharing this information and nothing to hide; The Researchers must work together to find the Infected Masters.
    In addition to sharing analysis results yourself, you'll need to listen to what other people are sharing. The other Researchers should also be sharing any information they've gained.
    Be careful though! The Infected team won't be sitting silently. They'll also be "sharing information"... meaning that they will be lying about what their analyses say! Figuring out who the Infected players are will help you know who to trust and who to ignore.

TEST A PLAYER
    When you think you know who The Origin (or any other Infected Master) is, you'll want to cast a vote to test a player. Tap on the player's icon, and then tap on "Vote to test [Player]" If 50% or more Researchers agree on the same person to test, a test is conducted on that player. It's important to remember that the Researchers only have a limited number of tests!
    If the test is successful, the Researchers do not use up a test, and they learn that the person tested is an Infected Master. If the Researchers test all the Infected Masters, you win the game.
    If the Researchers test someone who is not an Infected Master, they spend a test and learn that the player they tested is not an Infected Master. If the Researchers use up all their tests, they lose the game.

Playing as the origin

Team: Infected
Infected Master: Yes
Abilities: All samples sent from The Origin are Infectious.

The most important thing The Origin can do is NOT GET TESTED. To do that, you will have several tools at your disposal:

KNOW EVERYTHING
    The Origin and the rest of the Infected team know what roles the Infected team has, and who is on the Researcher team. They can use this to their advantage when they lie about what samples contain.

INFECT RESEARCHERS
    When a Researcher opens one of your samples, they will become an Infected Minion, and they will lie for the Infected team. Get as many players as you can on your side!

PROMOTE MINIONS
    If one of your minions is trusted by the Researchers, you can promote that minion. All you have to do is send them a sample, and when they open it they will gain a chance of generating an infectious sample, further helping to spread the infection.

LIE
    When players send you samples, lie about what they say! You are one of the Infected Masters, so do everything you can to make the Researchers waste their tests on other players!

Playing as an Infected Minion

Team: Infected
Infected Master: No
Abilities: Can be promoted by The Origin (see "Getting Promoted" in the glossary)

So you've been possessed by an ancient horror that has been buried under ice for millennia... I know how it feels. But don't fret! All is not lost. You've got a new lot in life as an Infected Minion, and your main goal is to make sure that The Origin and any other Infected Masters do not get tested by the Researchers! How do you do this? Glad you asked!

KNOW EVERYTHING
    The Infected team know what roles the Infected team has, and who is on the Researcher team. They can use this to their advantage when they lie about what samples contain.

LIE
    Pretend you are still a Researcher! The Researchers don't know you got infected, so lie to them to throw them off the trail of The Origin and other Infected Masters.

GET PROMOTED
    If you lie well enough, The Origin will favor you. Open more samples from The Origin to gain a chance at generating infectious samples yourself!

Playing as The Corruptor

Team: Infected
Infected Master: Yes
Abilities: Can be promoted by The Origin (see "Getting Promoted")

Did someone just out themselves as a special Researcher role? Is a Researcher standing up, eyes full of excitement, and preparing to tell the group exactly who the Infected Masters are? Do you feel like just kind of being a jerk to your friend for no real reason?

That's perfect because you're The Corruptor!

CORRUPT
    Once per game, simply tap on a Research Team member's name on your device, and then tap "Corrupt." They will immediately be turned into an Infected Minion. By using his ability early on, The Corruptor can gain a powerful ally immediately. By saving it until later, you can break into a circle of trust, giving The Origin an ally on the inside to spread the infection. And, since your samples aren't infectious, many of the Researchers will vouch for you.

KNOW EVERYTHING
    You and the rest of the Infected team know what roles the Infected team has, and who is on the Researcher team. They can use this to their advantage when they lie about what samples contain.

LIE
    When players send you samples, lie about what they say! You are one of the Infected Masters, so do everything you can to make the Researchers waste their tests on other players!

Additional Roles

Once you've mastered the base game with The Origin, Corruptor, Infected Minions and Researchers, you may want to try out some of the more advanced roles!

THE VECTOR

Team: Infected
Infected Master: Yes
Abilities: Researchers that open samples from The Vector get unknowingly Promoted, and gain a +50% chance to generate Infectious samples without knowing it. Researchers who have this ability are still on the Researcher team.

THE RESISTANT

Team: Researchers
Abilities: The Resistant is immune to the Origin's (and only The Origin's!) Infection.

THE SCANNER

Team: Researchers
Abilities: When The Scanner opens a sample, in addition to the normal contents of the sample, they will see the role of the player who sent it to them.

GLOSSARY

TEAMS
    Players start on either the Infected team or the Researcher team, with roles distributed randomly.

WINNING THE GAME
    
The Researcher team wins if they test all of the Infected Masters (see "Tests").
    The Infected team wins if the Researchers run out of Tests (see "Tests"), if they run out of time (see "Timer"), or if every player is Infected.

ISOLATING SAMPLES
    All players isolate a biological sample every 30 seconds. These can be accessed through the tab on the left, titled "My Sample." These samples can be sent to other players. When a player receives a sample, they have the option to "analyze" the sample they received. A player may NOT analyze the samples that they isolate themselves.

    When a sample is isolated, it will be designated either "infectious" or not infectious. This is determined when the sample is isolated, which means a sample may not become infectious later.

ANALYZING SAMPLES
    A player who has received a sample from another player may choose to analyze that sample or discard it. This can be accessed through the middle tab, "Analyze." If they choose to analyze it and the sample is not infectious, the sample will show them information about the state of the game. If the sample is analyzed and it is infectious, it will infect the player, turning them into an Infected Minion.

    Analysis results are ALWAYS true. Even if a sample is sent from an infected player, the results of the analysis of their sample will be true.

GETTING INFECTED
    If a Researcher gets infected, they become an Infected Minion and immediately switch to the Infected team.

GETTING PROMOTED
    If The Origin sends a sample to another Infected player, when that player analyzes the sample they will gain an additional 50% possibility of generating an infectious sample in the future. The promoting ability is unique to The Origin.

TESTS
    Tests are how the Researchers win the game. If a Researcher thinks they know who an Infected Master is, they may cast a vote for that player. They can do this by tapping on the player's name in the main window, and then tapping on "Vote To Test [Player]." If 50% of the Researchers or more vote for the same player, a test will be used on that player. Infected players may not vote.
    The Researchers have a limited number of tests. If they test a player and that player is not an Infected Master, they use up a test. If they use up all their tests, they lose the game.
    If the Researchers test all the Infected Masters, the Researchers win the game.

TIMER
    A game lasts 10 minutes. If any Infected Masters remain that have not been tested by the time the 10 minutes are up, the Infected team wins the game.

BASIC ROLES
    Researcher

The Researchers have nothing to hide! They must share information and work together to figure out who is telling the truth and who is lying. The Researchers win if they test all the Infected Masters (see "Tests"). A Researcher will be turned into an Infected Minion if they open an infectious Sample (see "Infected Minions").

Origin

The Origin is an Infected Master. His/Her samples will infect Researchers who analyze them. If a sample from The Origin is analyzed, and the recipient is already infected, the recipient will become "promoted", and gain an extra 50% chance to generate an infectious sample.

Corruptor

The Corruptor is an Infected Master. They have a one-time ability to infect someone on the Researcher team once per game (the Corrupted Researcher does not have a chance to resist infection).

The Corruptor can use their power by tapping on a player's name in the main window, and then tapping on "Corrupt."

The Corruptor is an optional role, customizable by the host and will not appear in every game.

Infected Minions

Infected Minions are on the Infected team. They are NOT Infected Masters, and must protect the Infected Masters from the Researchers' tests. They usually do this by lying about the information they gain from their samples.
