It's a M-Monster!

Two players are in a haunted house with a roaming monster! Each tries to manipulate the monster's path so that their opponent gets caught, allowing them to escape.

The gameplay takes place in two phases. First the players take turns to place 15 room cards in a 4 x 4 layout, with one space. The player and monster cards are placed in the rooms during this phase.

Next, players take turns to rearrange the rooms by sliding one or more cards to fill the space, and then move the monster according to the instructions on its room card. The first player to be caught loses the game while the other player escapes.
