Platogo, an Austrian startup which we recently covered as being a Mini Seedcamp finalist, opens up in private beta tomorrow. Platogo, (as in Play Together Online) aims to be the one-stop-shop for simple online multiplayer gaming. You’ve heard of MMORPGs such as World of Warcraft, but Platogo focuses on simple, easy-to-learn, online flash games with nifty graphics which are easy to play, thus tapping into the far larger market of casual gamers. We have 50 exclusive Beta Invites for Techcrunch Europe Readers. The first 50 commenters on this post will get an invite code. And we’ll see if we can strong-arm the startup into handing out more. [Update: We got them to add 150 more].
