A very simple game rules-wise for what you do on your turn that underplays the subtle strategies involved in the game. It does have a slightly muddy scoring system that takes a playthrough to really understand its implications. After our first game, we were compelled to play again straight away, and have played it 10 times in 10 days at all possible player counts.
The way cards can be played, or saved to ensure you can score played cards is fresh and unique. Every turn is torturous, particularly deciding what to throw away, but it's that good torturous which tight, well executed games have.
There's a bit of bluff, and many chances to be quite clever despite the anguishing decisions. If you don't like games that require you to do a bit of simple card counting, you won't like this, especially at 2 players. But it's a good, solid “thinky filler” to quote Heavy Cardboard. Despite its simplicity, I don't see it getting boring any time soon.
Only 4 stars though, because, to be honest at this price point, I expected better card stock. It is literally the same card stock as a normal deck of cards that you might get from a book store and there isn't anything else in the box apart from the (clear and concise) rule book.
