Tap Knight: Dragons Attack is a free role-playing game developed by PREUS for Android devices. The game features a new stage called Devil's Tower, which is filled with monsters that players have never seen before. There are eight new Legendary items that players can collect to boost their fighting experience.

In the game, players must strike down monsters that block their path and clear each stage to unlock new ones. If players get stuck, they can play previous stages to level up and upgrade their items. The ultimate goal is to defeat the Great Demon on the top floor of the Devil's Tower. Each stage has its own set of monsters and Boss monster, and tougher monsters will drop more Gold and XP.

There are several Spirits that will help players in their adventure. Players can awaken them from their seal and summon them. They can also collect Legendary items and upgrade them to greatly boost their hero's performance. Additionally, players need Devil's invitation to enter Abyss dungeon, where monsters are much tougher, but they will drop more Gold and items. The game culminates with the great evil Dragon waiting for players, and they must vanquish it and bring peace to their hometown.
