MiniDungeon is a small adventure game on your watch. The goal is to survive to the 20th floor of the dungeon and defeat the final monster there. In order to aid you with this task, you have a sword to deal physical damage to monsters. You will also find in the dungeon potions to heal yourself as well as offensive items to help take down the more powerful monsters.

While the app is running, once per minute there is a random chance of an event happening. You can end up finding a useful item, finding the ladder to the next floor, or being attacked by a monster. The farther you go in the dungeon, the stronger the monsters become. As you defeat monsters, though, you will also gain in power.

If you wish to pause your adventure, simply use the select button to enter the main menu. There is also the ability to turn off the vibration alert through the options menu.
