Greenlight Redlight is a simple and fun game suitable for players of all ages. The game rules are very simple, players need to move forward at the "green light" and stop moving at the "red light". There are multiple levels in the game, and the difficulty of each level gradually increases. Players need to react faster to pass the level.

There are two modes in the game: single player mode and multiplayer mode. In single player mode, players need to pass each level as quickly as possible to achieve the highest score. In multiplayer mode, players can compete with other players to see who can pass all levels in the shortest possible time.

There are also some special items in the game, such as time accelerators and reducers, which can help players pass levels more easily. In addition, the game also has some hidden colored eggs that players can discover through exploration.

The player stands behind the starting line and waits for the referee to start the game. When the referee calls out the 'green light', the player must run forward as fast as possible.

When the referee calls out a 'red light', the player must immediately stop and not move forward. If the player is still moving at the "red light", they will be eliminated.

The game continues, and the referee will shout "green light" and "red light" at random intervals until all players reach the finish line.

The first player to reach the finish line is the winner. If multiple players reach the finish line at the same time, they can play a round of "finish line battle" until only one winner is left.
