1. In the game "Brothers of the Three Kingdoms", players can move the screen up and down, left and right, so that the balls in the screen can move. Every step will consume a mobile opportunity, and the system will randomly add a ball to the screen after the move.

2. The balls of the same level will merge into a ball of a higher level after collision, and the highest level 10 can be synthesized.

3. Whenever a meatball is successfully synthesized, the player will get the corresponding level of points. The higher the level, the more points you get.

4. When the player can't move, the game is over. At this point, the player can choose to restart the game, or wait for the meatball plate to be reset once a day to restore the game to its initial state.
