Santa really does not have an easy task. Every year, he must go to give gifts to children around the world sliding them down the chimney. To save time, he prefers to drop them from his sleigh. However, he must aim and release gifts at the right time, otherwise gifts may fall off and end up in the snow, without anyone finds them.
In dropping objects games, you'll have to drop items at the right time to complete missions. There are often games featuring Santa Claus, but there are also other types of games, with other objects than gifts.
