In Construction Zone, each player is trying to construct new buildings. Each turn, players have access to resources; the basic ones can be taken easily from a draw pool, but you may also trade them away for advanced ones. At any time on your turn, you can also construct one building. To do so, you must play a certain number and combination of resources, then take (construct) the corresponding building. Construction is a bit tricky, however, as at any given time only three buildings are available for players to construct and any player may construct any building. Thus, you may be collecting resources for one building, but another player manages to construct it first, forcing you to readjust your plans. The first player to construct a certain number of buildings (depending on the number of players) wins.
