Dots has been out a while and, though it is a fantastically addictive game — we rate it highly — the nature of mobile gaming dictates that titles get less interesting over time. That’s probably why Betaworks is breathing new life into Dots by adding a challenge mode.

The new game format lets you play against friends using Facebook or email. Rather than merely plodding along on your own against the clock, players go head-to-head for 60 seconds.

If, like me, you were a fan of the game but found your interest waning as other titles came out, then this update might revitalize your addiction.
