There are some badges for unlocking game types and special puzzles and badges in bronze, silver, gold, platinum and ultimate levels in several categories as follows.

Score
Quickfire
Multiplier
Performance
Token
Pondering
Progress
Addiction

Nearly all of these you'll get just by playing quest mode. You will need to get to level 100 to get the ultimate progress badge. By the time I had done that I had all the badges apart from the last three pondering ones (given for taking time thinking).

Easiest way to get these last few is to do the special stages and just leave the game running and not completing the grid. After a period of time (some minutes) complete the grid and you should get the next level badge.

PS a general tip for the game is you can pause at any time and still see the grid. The clock does not decrease when paused. The game is easy anyway so you probably won't need to do this!

Another tip on getting some of the ultimate badges is to not do them or attempt them in Quest mode, but to instead go to one of the special subject-based game types - for example, countries and capitals.

Pick the subject based game type that you feel really comfortable with, or which you have the most knowledge of, and complete as quickly as you can a couple of the puzzles. The knowledge you have of this specific subject area should help you complete the grid quicker and therefore get you closer to some of the ultimate badges.

A final point - the ultimate and platinum pondering badges will take a long time. My advice - set up a timeless game, get yourself one move from finishing a level and then go off and make a cup of coffee. Allow about 20 or so minutes to get the platinum one, and about 30 to get the ultimate one.
