Like Warlords with different puzzle system..
Multiplayer is possible (PS3) both online and locally. The game has both a a story mode or you can jump right into a puzzle. There is an online leaderboard as well.
Keeping all things in perspective, this was a $20 download from PSN. I have easily got that much more value out of it and I am only about 5% through the game. I can see a point where the puzzles may get old but so far I have seen at least 4-5 different variations on the puzzle types and I suspect there may be more.
Surprisingly, this is one of those games where you can look up and you have been playing for hours!
