Use these settings to give everyone in the league a fair chance at picking up players. Sunday - Tuesday means all unowned players will be placed on waivers at 10:00am PT each Sunday with the claim period ending at 11:59pm PT on Tuesday. First game of the week - Tuesday means all unowned players will be placed on waivers at the start of the first game for that week with the claim period ending at 11:59pm PT on Tuesday. Game Time means all unowned players will be placed on waivers at the scheduled start time of their game. In Game Time Waivers, players on a bye week will be placed on waivers Monday night at 5:30pm pacific time. Continuous means that all unowned players are on waivers at all times. Waiver claims are processed on fixed days of the week as defined by the commissioner. When a player is dropped, he must remain on waivers for a set number of days before he can be claimed; that number of days is indicated by the Waiver Time setting.
Note that while changing your waiver rule or continuous waiver clear days during the season are allowed, changing either setting can lead to confusing or unexpected behavior. In particular, if your league has any outstanding waiver claims on players, or has players on waivers due to being dropped or newly added to the game, when you transition between modes or change clear days, players may not clear waivers when you might predict or expect.
