Place pieces with numbers like in a crossword and check the sums.
This puzzle can be played by anyone who can add two numbers. Based on the crossword rules, but uses numbers instead of words. The sum of digits of the numbers is the clue. A logical blend of sudoku (the japanese number puzzle game) and the Crossword (popular puzzle of western world). A great game for logic game buffs.
Just plain, simple and challenging. Just what I wanted. No bells, whistles or music!!!
Probably quite good...

Pros
Looks good in the screenshots etc.
Cons
License says this is "tellware" - i.e., you promise to tell all your friends about this game. For fear of looking like an idiot to all my friends (many of whom wouldn't be interested in this type of thing), I haven't installed it.
