Loslassen

live quiz and reaction tool

What is this

A host builds a game with slides, questions, and polls, then shares a PIN. Participants join on their phones. No accounts or installs needed.

Pages are either non-interactive (text, images, mindmaps, facts) or interactive (quizzes, polls, ranking, sliders, hotspots, number estimates, binary choices, emoji reactions). Responses come in live, faster correct answers score more, and a leaderboard tracks results.

"Loslassen" is German for letting go.

Running a session

  1. 1
    Get an account — you need the passphrase from whoever set this up, then register at /identity/register.
  2. 2
    Build a game in the Editor. Add pages, mix types, set correct answers where it makes sense.
  3. 3
    Start a session at /play/start. A PIN and QR code appear in the lobby — put it on the projector.
  4. 4
    Advance pages from the host panel. After interactive rounds you get a results view with answer distribution, then the leaderboard on finish.

Joining as a player

  1. 1
    Go to the main page or scan the QR code on screen.
  2. 2
    Enter the 6-digit PIN. Pick a name and an emoji — that's your avatar.
  3. 3
    Wait in the lobby. When the host starts, answer each round before time runs out. Speed matters — identical scores go to whoever answered first.
