When your kids complete their quests, they get coins and experience points that they can use to grow, customize, and care for theirvirtual companions (Doters). Quests can be anything from chores and exercising to learning and completing homework assignments -- the tasks are endless. You can help your children build good habits and discipline by making quests recurring. You can assign and easily track allowances to quests too, turning your standard chore chart into a fun, engaging game that is great for the whole family.By creating a game around real-life chores and tasks, Joon encourages kids to complete these tasks. This saves parents from nagging and repeatedly asking their kids to do important things like chores, studying, and exercising. Better yet, Joon turns kids into self-starters where they will proactively start doing these types of tasks on their own without parents even having to assign any to them. |  | Seed | Jul 01, 2023 |  |
