Jewels 2 is a puzzle game set in an archeological dig were a pre-sumerian culture left a great treasure. To unlock the treasure you must uncover 24 rune tokens from several places in the dig by solving for each one a logic/pattern recognition puzzle of varying difficulty. The main game screen consists of a map from where you can go directly to each puzzle as well as other interesting sites. There's an in-game journal that offers hints for most puzzles and if you are really stuck you can also consult with the digitally-captured professor Bhandam (the guy in charge of the dig) for hints.
The game also offers two difficulty settings for each puzzle.
