About this game
Battle Boss is a management game inspired by classic creature collector games. In the world of Battle Boss, trainers take part in battles with their creature companions, known as battlemon. And in this world, you take on the role of a Battle Boss - someone who battlemon trainers seek out to test their skills.
Every Battle Boss has their own battlemon gym, and you've been tasked with turning yours into a thriving haven for skilled battlemon trainers. Defeat challengers, manage your gym, and prove your worth as a Battle Boss!
After choosing a location for your gym, you'll start with an empty building, and it's your job to transform it into a battlemon trainer's paradise! Decorate your gym to improve its appeal and attract more visitors. Unlock more advanced decorations and upgrades for your gym by winning battles! Hire gym trainers to help keep up with a growing demand of challengers. Add amenities to your gym to keep trainers and their battlemon happy!
A well-decorated and staffed gym will attract lots of trainers, while an empty, messy gym will struggle to earn visitors.
Battlemon trainers come to you to prove their worth - so give them the challenge they want! Test challengers' skills in tense turn-based battles. Take advantage of battlemons' elemental strengths and weaknesses to win battles. As you defeat trainers, your reputation will grow, attracting even stronger challengers and unlocking even stronger battlemon for you to use!
Becoming an excellent Battle Boss may draw the attention of the Battle League - an elite group of battlemon trainers considered the best of the best. Prove you're strong enough, and you could earn an invite to join their prestigious group!
