   "PacNEM is an open source multiplayer Pacman browser game. It is a
   showcase for how easy it is to integrate blockchain features into games
   or applications. This game uses the NEM blockchain to reward players
   with various vanity tokens and for player high scores with NEM mosaics.
   Also, the PacNEM game integrates a Sponsor Engine which showcases how
   to implement instant payments in the advertisement industry for daily
   ad views with NEM mosaics.
   PacNEM uses the NEM blockchain in many different ways and aims to be an
   example of possible implementations of NEM features in your games or
   applications. This includes a secure implementation featuring mosaics,
   payment processing, multi-signature accounts and multi-signature
   transaction co-signing – all this without the need of developing
   in-game wallets! You can let people play with their own NEM wallets!!"
