Seeing how we always get Word Search Puzzles, which tends to be a bit boring by now. How about a different kind of puzzle like:

1. Crossword Puzzle. More challenging for the brain to find the exact word to put into.

2. Card Memorize. Do a bit of flipping cards and try to find the same exact pictures (2 for easy, 3 medium) and try to be the fastest. (marking the ranks just like how the score on opening pack works.

And a bit of upgrade to the Word Search Puzzle, maybe the ability to rotate the Puzzle board to make a fresh search point?
