The idle game Idle Mobs Farm offers a wide variety of monsters, including skeletons, goblins, orks, and more. Purchase the monsters, and they'll generate income for you on their own.
Begin by assembling a mob of mobs before beginning to develop a farm. Your initial source of income will come from it if it's still living.
The next step is to build a mob-spawning farm that runs automatically. When they pass away, the money will instantly go into your account.
You must enhance mobs if you want to boost revenues.
Keep in mind that you won't be able to make any more mobs if the limit has been reached.
Have fun and good luck!
