The broad structure can be utilized to formalize games with a period sequencing of moves. Games here are played on trees (as envisioned here). Here every vertex (or hub) addresses a mark of decision for a player. The player is determined by a number recorded by the vertex. The lines out of the vertex address a potential activity for that player. The settlements are indicated at the lower part of the tree. The broad structure can be seen as a multi-player speculation of a choice tree. [46] To settle any broad structure game, in reverse enlistment should be utilized. It includes working in reverse up the game tree to figure out what a levelheaded player would do at the last vertex of the tree, what the player with the past move would do given that the player with the last move is normal, etc until the main vertex of the tree is reached.[47]
