Dynamons 8 returns players to the Dynamons universe in an all-new monster-trainer, battle-arena adventure. The player's guide, Jovani, introduces the player to a location known as the Chinese Festival, where they can find and catch wild monsters called Dynamons, win domesticated ones from the teams of other trainers and captains, and build up their own team to reach captain status.
All monsters represent elements like fire and water. Jovani tests the player's skills in a turn-based battle, and then the player receives their first Dynamon. During a battle, they select cards to perform various strikes to defeat their opponent, including magic, overhead and slash ones. In later challenges, they can also use healing items and mystery weapons and swap teammates during battles. When they perform well, they receive coins, crystal shards, and other useful objects such as discs for catching monsters and powerful monster snacks.
The player faces off against wild Dynamons and other teams on the stone path that winds through the festival location. If they win a battle, they receive the opportunity to collect their weakened opponent on a disc. If they possess enough shards, they can also level up one or more of a Dynamon's attack, defense and aiming areas after the battle ends.
Dynamons 8 allows the player to use their coins to purchase objects and perform other tasks. If they run out of coins, they can enjoy these options by watching videos.
