There are plenty of games around that are built to be played any time. There are few, sadly, that specialise in being played under select conditions. Like if you're stressed. Or have stumbled home from the pub at 3am.
A puzzle game we've featured previously on Kotaku, Chime may at first glance appear familiar. You have blocks of different shapes that have to be placed in order to make them disappear. So far, so Tetris. Yet there's also a strong musical influence in the game, apparent not only in the consistency of the tunes, but in the way the music is shaped to serve the puzzles. So far, so Lumines.
