Idle Santa Factory is a casual semi-idle simulation game that features a Santa's workshop theme. Santa Claus needs the player's help with preparing the toys and presents to pack in his sleigh before the big night! The player directs Santa's movements to start up toy production and present wrapping conveyor lines, perform upgrades and hire elves to make the process faster, and drop the presents at the sleigh to trade for cookie currency and prepare for distribution on Christmas Eve.
The player starts with a small balance of money that's represented by an iced Christmas cookie near the top-right corner of the screen. They can use these funds to open up their first toy production and gift-wrapping machines.
Once the player has enough available wrapped presents, they direct Santa to take the presents to the sleigh to exchange the items for more cookies. Although Santa walks slowly initially and can only carry three items at a time, the player can use their cookie currency to perform upgrades. For example, they can increase Santa's speed and carrying capacity and hire the elves. They can also set up more machines with new toys and wrapping options.
Idle Santa Factory allows the player to perform some upgrades without cookie currency. The player merely needs to watch ad videos.
