Goal of the game is to have most roof pans in the own colour on the roof and also some ladders at the end of the game. Therefore as often as possible enemy tiles have been included in the game, flipped and thus transformed into its own color. This mechanism is known by Othello. If you play with 2 players, use the half of the board. If you play with 4 players, each 2 use their half of the board. It is not possible to play with 3. Each player has a character that is moved according to the dice roll. The target field specifies what the player is allowed to make. Options are: a) place one roof tile of his color onto the roof b) place two roof tiles of his color onto the roof c) miss a turn d) draw an event card and execute it immediately e) Interim Evaluation trigger (here ladders come into the game) The game ends when one half of the roof is fully occupied. Each roof tile is worth one point, each conducting one another point. Whoever has the most points wins the game. This was published by Ravensburger as a commercial game for Braas Systempartner
