Folks who missed the opportunity to grab Bicolor when it was offered for free in the Apple Store app will be happy to hear that it's gone on sale again. Apple is offering the popular game for free from now through next Thursday as part of its App of the Week promotion.
For those unfamiliar with the title, Bicolor is a deceptively-complex puzzler that tasks players with solving 240 handmade puzzles. In each level you must figure out how to draw a path with one color, and then cover it up with another using the right amount of moves.
