Flash Focus is a $20 spin-off of the Brain Age series, and is well-worth the value.

User Rating: 8.5 | Miru Chikara o Jissen de Kitaeru: DS Ganryoku (Medikara) Training DS
Flash Focus recieved mixed reviews because it was 'debatable' whether or not the game actually helped your eyes. It will not seem as if it does at first but after a few play-throughs you quickly realize how much of a great value this game is. You go through some simple-to-VERY hard mini games that test your eyesight. The simple idea is worked out well, and really helps sometimes.

GAMEPLAY: 8.5/10

While, honestly, the developer's focus in Flash Focus wasn't to make a visually stunning game, it is actually very nice. The sports games (baseball, the punching one, etc.) feature some nicely rendered graphics.

GRAPHICS: 7.5/10

There are some simple tunes, not much but is well suited for the game.

SOUND: 7.5/10

This game is meant to be played every day and with its addictive system and replayability, I bet it will be.

LASTING APPEAL: 9/10

Overall, Flash Focus is well worth the value if you are looking for fun, yet challenging games that can actually help your health.
