Games with the Collaborative mechanic feature the players versus the game. Unlike traditional games where all players are out for themselves, a collaborative game lets the players work together to try and solve the puzzle, discover the solution, or in some way 'beat' the game.
Examples of games using the Collaborative mechanic include Pandemic, Forbidden Island, and Forbidden Desert. This mechanic is one of the best at foster soft skills. In all three of the above examples critical thinking, communication, problem solving, team work, and leadership are necessary for the group to succeed.
