Bubble Gum Simulator Infinity introduced the Light and Dark Event along with the final Beach Festival update on June 7, 2025. This event commemorates the 300 million and 400 million visit milestones at the same time, providing players with two brand-new Eggs with various Pets. As part of this, the game has introduced a day-night cycle that switches between the two every four hours.
Let’s take a thorough look at the day-night cycle and everything that changes during the day and the night.
How the day-night cycle works in Bubble Gum Simulator Infinity

The day-night cycle in Bubble Gum Simulator Infinity is exclusive to the Light and Dark Event, which is entirely focused on the two event-specific Eggs: the Light Egg and the Dark Egg. Only one of these is accessible at a time, and after every four hours, the day-night cycle switches, making the other Egg available.
During the day, the Light Egg can be bought and hatched for 2.5 million Coins, offering seven Pets. Once four hours pass, the cycle will switch and give you access to the Dark Egg for 2.5 million Coins instead. It has a pool of seven Pets that are equally as rare as their light-themed counterparts.
The end date for the Light and Dark Event and, by extension, the day-night cycle is currently unknown.

About the Light and Dark Eggs

The Light and Dark Eggs are functionally identical; the only differences between them are purely visual. Their costs, the number of Pets, and the multipliers the Pets offer are the same. Furthermore, both of their Pet pools include the Secret Immortal One. So, you won’t be limited to a single Egg if you’re pursuing a specific multiplier and you have an equal chance of getting the Immortal One.
In the table below, you’ll find every Pet, their multipliers, and their hatch chances upon opening one of the aforementioned Eggs:
