This is part of a range of Lego games made from standard Lego pieces, and that means you need to build the board and pieces yourself before you start playing.
Once you have built it, you have a game for two to four players. The board represents a small graveyard, and the pieces are monsters that sit on top of the headstones. The object is to get four monsters in a row - basically the same as the old game Connect Four. There are some additional rules. You roll a die to determine what parts of the graveyard you can put your next piece. Sometimes, you get the option to replace another player's monster with yours. There are skeletons, which act as wildcards, and there is a fearsome spider that can scare away all the monsters in one of the quarters of the graveyard. These additional rules make the game much more interesting, while retaining the simple and easy-to-understand rules of Connect Four. Lego, as a creative company, encourage you to modify the rules or add your own.
The construction and gameplay is much more straightforward than either
LEGO Games 3841 Minotaurus or
LEGO Games 3843 Ramses Pyramid, which actually makes this game more fun, because you can get set up and start playing much more quickly. It's a good family game; there's enough strategy to make it interesting, but there's enough randomness to give everyone in the family a reasonable chance of winning. Each game is unlikely to last longer than 15 minutes.
There's nothing terribly original about this game, but it's good simple fun, and you can't really say fairer than that.
