The kids and I have been playing HabitRPG.  In this online game, we battle evil monsters like Laundry and Tidying Up so that we can win experience and gold.  How?  By sticking to our daily habits – taking baths, doing our homework, and changing the litter box.  Succeed, and we slay the monsters.  Fail, and we lose health points.  We can use the gold to buy rewards like extra iPad time.  The game is simple, but fun, and has been great for keeping the kids (and sometimes me) on task.  The kids like to check off what they’ve done and then buy more loot in the game.  I like the daily reminders to finish some household tasks.

The game is free, but there are bonuses that come with a paid subscription.
