"ひとっち~つながれ一族" is a human development game where players raise their offspring through generations, expanding their family tree.

The game progresses through four stages: kindergarten, elementary school, high school, and adulthood (employment), with each stage lasting 3 hours before automatically advancing to the next.

Players can expedite growth to the next stage using "shorten growth time" items. As characters mature, their parameters increase, determining their occupation from a pool of approximately 100 options.

Players can marry their adult characters to those of other users, creating new descendants and continuing the lineage, with options such as occupation, spouse's birthplace, and completing limited NPCs.

Various items are available, including those to recover action points needed for development commands, increase action point limits, shorten growth times, and more. Gold earned in-game or purchased can be used to buy items.
