Overview
Colosseum is a board game by Markus Lübke and Wolfgang Kramer, published in 2007 by Days of Wonder and illustrated by Julien Delval and Cyrille Daujean. In the game, players attempt to attract the most spectators to the events in their arena.
Gameplay
The game is played in rounds, each round consisting of five phases (except the last round, when phase 5 is not played). In each round, one player is the first player, who does every phase first. The first player changes every round.
Each player has an arena where the events are performed, and starts with two possible events to perform. Every event requires a different combination of asset tokens, small squares depicting various people, animals, and objects that would be used in a performance; players start with some of these and can acquire more during the game.
Investing
In the first phase, players can invest. There are four choices:
Expanding the arena, which allows better events to be performed and increases the chances of a noble landing there.
Constructing an emperor's loge, which allows the player to roll two dice instead of only one when moving nobles.
Buying a season ticket, which is worth five additional spectators.
Purchasing a new event, all of which require the arena to be expanded at least once. Some require two expansions.
