In honor of Ready Player Two, Roblox is launching a themed treasure hunt with seven user-generated games inside the Roblox platform.

Roblox is one of gaming’s quietest success stories. Since debuting in 2006, it has grown to around 4.5 million monthly active players that love Roblox’s user-created games and worlds.

Long-time children's game maker Toca Boca will roll out its first multi-player experience in a direct challenge to Roblox's primacy with young players.
