Number Plus 1
NCS will start a timer. NCS is the only one who knows how much time remains. Operators transmit an incrementing number to other operators until time is up and NCS breaks in.
The object of the game could be to see how high operators can get the number before the timer goes off.
Alternately, the last one to transmit is out and play resumes with the remaining operators until only one operator remains.
NCS starts
OP1 de NCS 1
OP1 chooses another operator and increments the number
OP2 de OP1 2
OP2 chooses an operator and increments the number
OP3 de OP2 3
Transmissions continue until NCS breaks.
In addition, the roster of operators could be published so that play circulates in order through the roster.
When operator 3 gets out, operator 2 must now transmit to operator 4. If someone makes a mistake and transmit to the wrong operator, then they are out.
For example, if OP2 is supposed to transmit to OP4, but accidentally transmits to OP3, then OP2 is out of the game.
