Gladius

In Gladius, play as cunning Roman spectators trying to make the most
money by betting on rigging the gladiatorial games. Each round, players
secretly place bets on competing gladiator teams. Through the skillful
use of underhanded tactics, players can help and hinder teams to alter
the outcome of each battle. The player with the most money at the end of
three rounds wins! Will you walk away with toga pockets brimming full
of gold, or will you be left without a single denarius to your name?
