Roblox University, more commonly called RobloxU, is a repository of lessons on building games with Roblox. Each lesson series starts from the ground up and describes how to make a complete game using the tools Roblox offers. These lessons range in difficulty, so there is something for everyone: whether you are a brand new builder or veteran scripter.
