Summary: an excellent version of the game with an easy to use interface, the coloured bar highlights both row and column making it easy to see the numbers that are in both and to help avoid making duplicate number mistakes, although some of the puzzles in each section are a lot harder than they should be for the section that their in. It is well worth getting regardless of your level.
Summary: Not the easy to use product I expected. Seems to start at a higher level than what could be called beginners. Apart from muting the DS you dont seem to be able to stop the annoying accompanying music
Summary: I agree with a previous reviewer, this game's interface is irritating compared with that in the 'Brain Training' games. Space on the screen is wasted on background images making the grid very small. So much so that the small 'provisional' numbers are almost illegible. The number of puzzles is impressive and the difficult ones are pretty challenging. Being able to go forwards and backwards through moves is handy too, although not an essential tool.
