Unlimited Quotes is the on-demand version of Quote mode: instead of one line a day, you get a fresh quote every round. Read the line, guess which Sidemen Among Us player said it, and hit Play Again to keep going for as long as you like. You have six guesses per quote.
Each wrong guess narrows things down, and after three misses an optional hint unlocks (first initial, nationality, and creator group). Quotes are dealt from a shuffled deck, so you'll see every quote once before any repeats — and never the same one twice in a row. There's no streak to protect; your daily plays/wins/losses simply reset at midnight. Strategy notes are on the how to play page.
