There's usually some description of why a game is marked playable, I think by clicking on the yellow symbol you'll get the lost of reasons.
The most common reasons are requires using the on-screen keyboard and small fonts. Some playable games are completely fine: Occasionally I find a game that only requires using the keyboard once or twice but is still marked 'playable'.
