Original sentence: Early hunts were either linear (after solving one puzzle, a new puzzle would be revealed) or all the puzzles were available at once and nothing new was added through the course of the hunt.The last eight hunts have all had a round structure, allowing puzzles to be released at different times
Edited sentence: Early hunts were linear (you get a new puzzle after you solve the one you have) or you started off with all the puzzles at once and nothing new was added.Having a linear hunt is usually problematic, and modern hunts have tried to eliminate the burnout that can happen from seeing the same 30 puzzles for the whole hunt.Thus, the last 8 hunts have all had a round structure, that has allowed puzzles to be released at different times
