Rules simple but have some difference from monopoly:
Property have 3 types of house each house have own income and build cost.
The more same color property you have the better houses you can build,
With single property you can build first houses, don’t need buy all cards same color to start build houses.
Also main important difference is that player can change how many they move,
players can skip moves:
if its player first turn,
if hi stand on Generator,
if not buy property and skip it,
if hi stand on someone else property,
if hi stand on own station (not work if you buy it in this turn)
