Hallow's Eve 2016: Trick or Treat Countdown was an event that was sponsored by Nerf. It served as an extra prequel to Hallow's Eve 2016. Unlike other events, only the prizes were revealed and players were given a hint and had to figure out which game the prize could be found in. A new prize and hint were revealed every few days. The games featured were Design It, Blox Hunt, Retail Tycoon, MeepCity, Super Bomb Survival and Dinosaur Simulator with one prize per game.
