How do you unlock the roadblock in farm hero saga?

Answer 1

You can't. You can ask your friends forever and they will never get the request, so you cannot unlock the game. They are trying to force you to buy gold bars

Answer 2

To unlock a roadblock in Farm Heroes Saga, you typically need to match cropsies or use special boosters adjacent to the roadblock to clear it. Keep matching cropsies strategically to unlock and progress through the level. If you get stuck, you can also use gold bars to buy extra moves or boosters to help clear the roadblock.
