Its really up to you.
Its a dungeon crawl.

So some players grind a lot on Friday's when the new content comes out.

Some people run a few dungeons and battle a few times daily in the Arena.

Trying to stay away from the "you have to play daily" to more of a "play and enjoy this week's content or this month's event"

The web based game is just part of the gaming world we are building based around Thunk.

Happy easter!
