This game only has 350 games AFAIK
(100 Sudoku, 100 Kakuro, 50 Slither Link, 50 Nurikabe, 50 Akari (aka Light On)
Beat All Slither Link, All Nurikabe, All Akari, 60 some Sudoku and 80 some Kakuro in one night. The game is way too easy and short
The most difficulty Light On barely takes 20~30 seconds, Nurikabe about 50~70 seconds, I suck at slither link but still most were less than 2 minutes.
Stylus control is fine, except it is picky about double tapping a line to make a X or removing in slither link but you can drag around 0 to mark Xs instead of tapping 4 times.
Nurikabe has similar problem with slither link, but since the box is bigger it isn't as frustrating
Sudoku control is great
Kakuro is just about the same as puzzle series
I didn't have problem with Akari either, there was some problem of marking two conesecutive cells with lights because of drag instead of multiple touch feature, but it's conveniant to mark lights around 4 or dots around 0 so it evens out.
It's more like a sampler than hardcore puzzle game. A great game if you can't figure out how to play some puzzle games, you can grab this one try different games learning with English tutorial, and 50 puzzles that will get you used to the rules. Then grab the Japanese puzzle series game of the ones you liked, for more challenge.
I completed all puzzles in Puzzle Series Vol 12 Akari, and then never replayed it. After playing this I had the urge to put it back and play again. My high score is already awesome but Akari is sooo fun~ I don't mind replaying it. It's more logical to me than Nurikabe or Slither link, things branch out too often without hint, Brain Buster doesn't have that "try thing out and cancel the whole thing" system so it was a bit down.
