Pick'em (straight up)
Players pick the winner of each game. One correct pick equals one point unless you configure tiebreakers for weekly wins. This is the classic office pool format.
Confidence
Players assign a confidence point value to each pick (higher points on picks they feel strongest about). Correct picks earn those points; wrong picks earn zero. Rankings sort by total confidence points.
Survivor
Each week (or slate), players pick one team to win. They cannot pick the same team again later in the season. A wrong pick eliminates that entry. Last entry standing wins.
