Play Solo was a feature in which a player could access a place and edit it in a singeplayer mode, unable to play with any other people in the mode. It was removed some time in 2014 or 2015.[citation needed] When this mode existed, owners of games could always play in this mode in their own games, however, the play solo feature would not be available to the public unless said place was uncopylocked (see here.) It was similar to Build Mode. You could save your work as a model if you liked it.
