Mr Cope says the game is as realistic as possible and includes having to present a draft budget to parliament.
Players face national and international constraints on their budget
choices and Cyber-budget includes negotiations with other ministers and
unexpected events, the French news agency AFP reported.
"The idea is that when we cut taxes, we can't do it without creating
deficits," Mr Cope told French television ahead of the launch.
"It allows each person to get familiar with how (the budget) functions.
"In this game each French person can pretend they are the budget
minister and make decisions to understand how much each [ministry's]
budget costs, education spending, military spending, how it's all
organised and see what kind of decision we can take when we want to cut
taxes," Mr Cope explained.
