Let the bricks floating with the river touch your brick raft, and they will become new members.
There are many dangerous enemies in the river to stop your progress, and those towers from nowhere can help you defeat them.
As we all know, three one-star things can become two stars, three two-star things can become three stars, it's very simple.


There are two currencies in the game:
1 Gold coin is a temporary currency in the level, you can use it to strengthen your tower in the level, distribute it reasonably, and spend it as much as you want.


2 diamonds can be used to permanently strengthen the skills of the tower, which is very precious.

Enemies in the game sometimes drop a lot of junk, and sometimes the dropped equipment is very useful.
