How to play

Classic is the heart of the game. Every day at midnight UTC one character from the cast is secretly chosen as the day’s impostor. You have eight guesses to identify them. Type a character’s name into the input, pick them from the dropdown, and the guess locks in.

Reading the clue tiles

Each guess reveals a row of eight tiles comparing the character you guessed to today’s impostor. Every tile carries its own label, the value for your guess, and a verdict:

• MatchThat clue is exactly right.
• HigherThe impostor's value is higher than your guess.
• LowerThe impostor's value is lower than your guess.
• No matchA different value, with no direction to go.

Numeric tiles spell the direction out in plain words: an age tile that reads Older means the impostor is older than the person you guessed; a subs tile that reads Fewer subs means they have a smaller channel.

The eight tiles

Person

The character's portrait.

Nation

Country of origin.

Height

Subs

YouTube subscribers, in millions or thousands.

Group

Which creator circle they belong to.

Rules and streaks

• You have eight guesses. Using all eight without identifying the impostor counts as a loss.
• A new impostor is chosen at midnight UTC. The countdown shown at the end of a round counts down to that moment, which may be earlier or later than your local midnight.
• Win a day and your streak goes up by one. Lose, and it resets to zero. If you don’t open the game on a given day, the streak picks up where it left off when you return.
• Progress saves automatically to your browser. Clearing site data or using a different device will start you over.

Strategy tips

• Lead with a diverse opener. A guess from a less obvious creator group gives you more information per tile than guessing a core Sidemen on turn one.
• Treat the arrows as your fastest eliminator. A single Older or Younger on age can rule out half the roster instantly.
• Don’t waste guesses on clues you already have. If you have the group and nationality locked, switch to age or subs.
• Use the All crewmates button. It lets you browse every character’s full clue card, which is handy when you’re down to three candidates.

Quote mode swaps clue tiles for a single line lifted straight from a Sidemen Among Us video. You read the quote, then guess which character said it. You get six guesses.

How clues work

Unlike Classic, the displayed quote never changes during the day. What changes is how much you’ve learned about the speaker from your wrong guesses. Every wrong guess is stamped Not the Impostor and stays on the board, so you can see exactly who’s been ruled out.

After three wrong guesses an optional hint unlocks. Nothing is spoiled until you ask for it, and you only get one: three clues are drawn for each quote, things like nationality, debut year or how many games they’ve played, and you keep one. It shows under the quote. Some quotes are obvious; others are a deliberate misdirection. That’s part of the fun.

Rules and streaks

• You have six guesses. The same character can’t be guessed twice.
• The Quote streak is tracked separately from Classic. Failing one doesn’t affect the other.
• A new quote drops at midnight UTC alongside the Classic rotation.

Strategy tips

• Use the tone of the quote. Some Sidemen have very distinct phrasing; losing your mind loudly is more Ethan than Josh, for example.
• Spend the hint wisely. You get one clue per quote, so pick the one that rules out the most people.

Unlimited is the “I can’t wait for tomorrow” mode. It uses the same eight-tile board as Classic and the same eight-guess limit per round, but instead of one impostor per day it gives you a fresh one every time you press Play again.

Rules

• You have eight guesses per round.
• The game never picks the same impostor in two consecutive rounds.
• Your daily plays, wins and losses counter resets at midnight, so each day is a clean slate.
• Unlimited is fully independent from Classic. Winning or losing here will not touch your Classic streak.

Strategy tips

• Treat Unlimited as your practice range. The more rounds you play, the better your instincts get for Classic.
• Vary your openers across rounds. Trying a different starting guess each round teaches you which characters give the most information up front.

Unlimited Quotes is the on-demand version of Quote mode. It uses the same single-line format and the same six-guess limit per round, but instead of one quote a day it deals you a fresh line every time you press Play again.

Rules

• You have six guesses per round, and the same character can’t be guessed twice in a round.
• After three wrong guesses an optional hint unlocks: one of three clues drawn for that quote, such as nationality, debut year or games played.
• Quotes are dealt from a shuffled deck. You’ll see every quote once before any of them repeat, and you’ll never get the same quote two rounds in a row.
• Your daily plays, wins and losses counter resets at midnight.
• Unlimited Quotes is fully independent. Winning or losing here will not touch your daily Quote streak.

Strategy tips

• Use it to learn everyone’s voice. The more lines you read, the faster you’ll recognise who phrases things which way. Handy for the daily Quote run.
• Lean on the tone of the quote. Distinct phrasing is your biggest clue before the hint unlocks.

Name the Crewmates flips the game on its head: there’s no impostor to find. Instead, the whole cast is laid out as a grid of blank tiles and your job is to recall every single one from memory before time runs out. Type a name, hit Enter, and if you’re right their tile flips over to reveal them.

Setting up your run

Before you start you pick two things:

• Time limit. Unlimited (no clock, just a stopwatch), or a countdown of 3, 5, or 10 minutes.
• Grid layout. Grouped splits the grid into creator circles with headers and a per-circle counter, while Ungrouped shows one wall of tiles with no grouping hints for an extra challenge.

Typing names

• The input isn’t a dropdown. Just type a name and press Enter to submit it.
• Spelling doesn’t have to be perfect. Matching is typo-tolerant and accepts a character’s main name or their alternate name or handle, so “miniminter” and “Simon” both land on the same person. Very short names need to be exact so they don’t collide.

Ending and scoring

• The run ends when you name everyone, press Give up, or the timer hits zero.
• Once it ends, every crewmate you missed is revealed on the grid so you can see who slipped your mind.
• Your personal best is saved per time limit on your device, and clearing the entire cast records your fastest time. There’s no daily streak; replay as much as you like.
