The rules

4 steps.

  1. Going around the circle, each player says one, two or three consecutive numbers.
  2. Tap the button showing the numbers you just said.
  3. Whoever is forced to say 31 is out, and the count restarts from zero.
  4. Keep going until one player is left.

The bit everyone gets wrong

You have to say at least one number. You cannot pass, which is what makes the endgame a trap.

What the phone does

The phone is the referee. It shows exactly which numbers each button says, tracks the count, and decides who is out.

It is a dealer and a scorekeeper, never a judge. It cannot hear the room and it does not decide who was right.
