Gifts add show, never points.

A gift is celebrated after the result locks. It never changes the time, a score, or anyone’s rank.

How to play

  1. See two thingsA table-tennis ball and the Tokyo Skytree, a puck and a rink. Both appear at the same size, and the question is how many of the small one make the big one.
  2. Type one numberChat has 20 seconds. One guess, one change. Guesses stay hidden until the lock, so nobody can copy anyone.
  3. Watch the scale snapThe view zooms to true scale and the count builds. The closest guess wins, and chat’s middle guess takes on the streamer’s.

Set it up in three steps

  1. Copy your OBS linkType your Twitch channel below and copy the link. It only reads your public chat and records nothing.
  2. Add a browser sourcePaste it into OBS, Streamlabs or Twitch Studio. 1920 × 1080 for landscape or 1080 × 1920 for portrait; the layout follows the size.
  3. Open the phone remotePhone remote support for SIZE SHOCK is coming soon. Until then, open the source’s Interact window in OBS: Space skips, P pauses and M mutes.

Reads your public chat only. No key, nothing recorded.

SIZE SHOCK reveal: the answer is 790 ice hockey pucks along a rink. The closest viewers, chat’s combined guess and the streamer’s guess sit on a measuring line.
The reveal: true scale, the answer, and chat against the streamer.

Questions

What counts as a guess?

The first number in a message: 42, 1,200, 1.5k and 2m all work. Links and emotes are skipped, and silly numbers are ignored.

How are points worked out?

By how close you are, on a ratio: exact scores 100, twice too high or low scores 69, ten times off scores 40. Every honest guess scores something, and there is no speed bonus.

Does the streamer play?

Yes, with one locked guess that stays hidden until the window closes. Chat’s middle guess is the chat brain, and the two go head to head.

Is SIZE SHOCK finished?

It is new on Twitch. It reads your public chat and records nothing on our servers. The phone remote and more platforms are coming next.

Can I play it without a stream?

Yes. Party mode puts SIZE SHOCK on everyone’s phone for family and friends, wherever they are.
