### 1/5 — Aggrivated!

*2011-02-19, version 1.2*

I can't believe I paid for this junk! It's crap and it won't open!

### 2/5 — Poor sudoku implementation

*2011-02-12, version 1.2*

A good sudoku game should have only one solution.  This version provides puzzles with multiple solutions leading to guessing and not pure logic.

### 2/5 — Colourko

*2010-09-01, version 0*

Great app. for beginners. I'd rate it 5 stars when able to input your own Soduku problems,otherwise it performs as described by the author.
