Ludus is a gladiator school game where players must improve their gladiators and compete with other gladiators to become the best. Players can purchase new armor, swords, and equipment, trade and earn money, and even buy and develop slaves to become gladiators. 

There are five different gladiator styles to choose from, and players must train their gladiators according to their chosen style. Players must also take care of their family while managing the employees most helpful to them. 

The aim of the game is to build a large and comprehensive gladiator school and create the most comfortable working environment for the gladiators.
