Fun dungeon crawl with nice mix of voluntary pvp. Well thought-out game. This game has a little bit of everything. You dont have to pay, but you likely will just because it improves the gaming experience. Overall, it is one of the better games out there for ipad/iPhone. Contrary to one comment, you do control how your character fights (although it is turn based), thus making it a game of skill, also, at least somewhat. Unlike many games, this is not a race for the highest level.
Update: Have been playing the game for almost a year. They repeatedly have events that are glitched and cause players to spend a lot of money. Sometimes they will immediately roll back the game. Recently, they waited for 3 weeks to take back items from players where players had put in additional time and money to build, and failed to make adequate compensation for the lost time and money. Their customer support has gone down to canned letters, not fixing issues, then asking if you are happy with the service. If you put money into this game and expect to build a character, it is at your own risk. I have taken away my 5 stars because of this.
