player and the players can spend to the Con to something that they want to. The productivity of each space can
increase by take the effect from the Life Board which the maximum of each space that can produce the Con
depend on the top-right or the origin price that the players buy the space and also the productivity can reduce
by the thief which will decrease in the half of Con that the space can produce but it not permanent because the
thief can move or die.
