Overview

Colosseum is a set-collection and auction game set in ancient Rome. Players are impresarios staging increasingly spectacular events in their arenas to attract the most spectators. Over 5 rounds, players invest in new event programs, bid on performers and assets at auction, trade with other players, and stage their shows. The player who attracts the largest audience to a single event during the game wins.

Components

Setup

  1. Place the game board centrally; position nobles on their starting spaces.
  2. Each player takes an arena board, starting money (30 coins), and a starting event program.
  3. Sort event programs by tier. Place asset tokens in a bag.
  4. Place podium tokens near the board.

Turn Structure

Each of the 5 rounds has 4 phases:

Phase 1: Invest

Players may purchase one new event program (from available face-up programs). Programs of higher tiers require more performers but score more spectators.

Phase 2: Acquire Assets (Auction)

Draw asset tokens from the bag to form lots. Players bid on lots of 3 tokens each. Multiple lots are auctioned per round. Bidding is open; highest bidder wins the lot.

Phase 3: Trade

Players may freely trade asset tokens with each other and/or buy tokens from the Emperor’s Loge (fixed prices).

Phase 4: Stage an Event

Each player chooses one event program to perform. The number of spectators depends on:

Actions

Investing in Programs

Bidding at Auction

Trading

Staging Events

Arena Upgrades

Scoring / Victory Conditions

The game is NOT cumulative scoring. The player whose single best event (highest spectator count in any one round) is the highest wins. This encourages building toward one spectacular show.

Tiebreaker: most total coins remaining.
