OK, so I just played 3 games of
Evagari, which no one has ever heard of because the guy who invented it hasn't had any luck marketing it. I didn't plan on playing it; it was just the first game I could jump into.
That said, it's a pretty awesome game. It's reminiscent of both chess (4 pieces per player. each with a different type of move: a "star/knight", a "circle/king", a one-or-two space "triangle/bishop", and a one-space "square/rook") and checkers (all pieces, except the circle/king, transform or flip into a circle/king under the right circumstances - sometimes inadvertently).
The board has four 4x4 sections (16 tiles in a section), with the 4 corner tiles of each section being raised. The 4 sections come together in a square, so the 4 center tiles (one from each section) form a platform in the middle of the board. A non-circle piece on the center platform at the start of your turn flips into a circle. The twist here is that instead of moving a piece, you can rotate your section of the board 90 degrees, pushing all the pieces into a different alignment with relation to the rest of the board. A section with no pieces on it is taken out of play, and adjacent sections can slide into that space instead of rotating.
You win by flipping all of your pieces into circles, by being the last player with a circle on the board, or by accumulating points from captured pieces. You lose when you have no circles on the board, or the game stalemates and you have fewer points.
Frankly, I was really impressed. It's complex without being complicated, it's pretty quick (he's apparently done "speed" games that took less than 10 minutes, I think we averaged around 20 - 30 minutes), and the transforming board really shifts the game fast. I would definitely play it again. (Another nice thing: because the sections are all identical and symmetrical, you can add on. I suggested, and he's intrigued by the idea of, playing an 8-player, 9-section game with a fixed center section and 8 sections around the outside. There are a lot of possibilities for variants.)
He's got videos here
http://www.youtube.com/user/evagari (I haven't watched them), and a website here
http://evagari.com/ (which is a little overwrought IMO).
Also, I really like the idea of a game that you could easily draw out on some paper and play anytime, anywhere.
