In Trespass both players set up large plastic numbers (0 through 9) on the first two rows of a 5X6 grid then each player secretly selects one of the numbers. The object of the game is simple... get your selected 'secret' number to your opponent's first row.Pieces may move, on a clear path, as many spaces that are open or make single or multiple 'jump' moves (similar to Chinese Checkers) or combine a move by sliding and then making a jump.Players alternate moving pieces with the only restriction being that they can't move a piece that was just moved by their opponent... moving your opponent's colour is allowed.If your secret number is moved to your opponent's first row, you win (whether you made the move or not). - BoardGameGeek
