Am I right to understand that the total cost will be 50

x seven for a total wager of 350

? If this is the case, I would only agree if it were not a "winner take all" scenario.
Does that mean that we each get to play each country once?
Will the games be in parallel or in series?
What is the nature of any communication? Are the games gunboat; public; or all?
Inquiring minds want to know.
