Teams should learn to recognize some coding systems.
Here, we introduce one. We give teams a poem to "solve."
The poem tells the coding system to solve the "mysterious" marks.

War drum# beat;
Leav# land behind.
And #ust move a fleet:
F#r from homeports kind.

In #rint, red is red;
A color on t#e map.
#n deck, dead is dead;
each haza#d a trap.

In peace sailors f#llow,
#riends against the water.
In print, not ye#low,
There must be sl#ughter.

Thus Slau#hter must increase
Until adm’rals #ignal peace.
