^Wrong.

Supply of water and games is not included.
Supply is the subject here, not "water and games."


On a side note, "Supply of water and games not included" is fine as we often use sentence fragments on printed signs to be more clear.

eg. One time use only.
eg. Breakfast not included.

The two sentences are essentially the same in your case. "Supply" can be used as a general term for 供給. They are both grammatically correct.
