"Ten Million" (10000000) is one of my favorite mobile games ever. It's a rather comical mashup of contemporary "match" puzzle games like Bejeweled and Puzzle Quest, and old school text-based Roguelikes. The only catch was you needed a mobile platform to play it.
But come tomorrow, you can grab it on Steam for PC/Mac. We were told by the developer, Luca Redwood, that Valve approached him in regards to bringing 10000000 to the PC, and the rest is history.
As for the price, I don't have a definitive answer yet, but Luca says it should be around "4 to 5 bucks," with a first week sale in tow.
