soccer game

i thought of creating a paper soccer game app...i googled it to see if anyone else made it already and i found that there was a paper soccer game made. then when i looked at the game and how it was played and its completely different from mine. so i was wondering if i could still make my version of the game. my dad is the one who introduced me to it when i was a little kid. to play the game you need a sheet of graph paper, and two colored pens. you draw the goals on each side of the paper determine where the center is and you're ready to begin. so each person gets to move three boxes in any direction, it could be up or down or diagonally. also the line you make doesn't need to be straight, you could change direction with each square you pass. for example, you could move straight up one square then make a turn diagonally for another square then up again. once you made your three moves its the next persons turn now this player has three squares to move. the players are not allowed to cross the lines that are already drawn on paper, they have to move around the use spaces. now the trick to the game is to try and trap opponent in the lines that are already there, and if the player successfully traps the other he gets to move seven squares and is allowed to go through the lines that are already there, plus if the player makes seven moves and is still in the middle of the lines that players gets additional seven moves until the lines is out in the open where the other player can make at least three moves. that is called a penalty kick, but the penalty kick can only go straight for seven squares without changing direction unless after seven your still inside the lines you could move in different direction. that is how the game goes and who ever scores first wins
