This page has been revised for the current stable version (41.78.16).

Help by adding any missing content. [edit]

Custom Sandbox allows the player to adjust the game settings to the way they like. After choosing a starting location, the player can choose their own options, or choose a preset to customise. In the Saved Presets box at the bottom, each default option is the same settings used in the default game modes.

*NOTE: the Character options have a set default 'difficulty' for each preset*

Time

Day length: is the time for an in-game day to take in real-time. This will affect how fast the player gets hungry or thirsty. Therefore, the longer the game day is, the longer it will take to get hungry or thirsty. This can be adjusted hourly from anywhere between 1 hour to real-time (24 hours), or 15 and 30 minutes. The default day length is 1 hour for all game modes.

Start Month: The month the game will start in. This will affect the current weather, foraging and farming. July will have greater harvests, whereas December will have poorer.

Start Day: This determines which day of the month the game will start in. The default for all game modes is the 9th.

Start Time: This determines the time when the game first starts, which will affect how much daylight the player will have on their first day. Daylight provides a buff to the player's sight. Zombies are attracted to light sources during the night.

Water Shutoff: The water will randomly stop working any day within this range.
