I am submitting my game here to see if it can be broken in a way that I can't break it through solo playtesting.
In summary, each player has 9 pieces. The pieces have a number on each side of them (like a coin): 1/2, 1/3 or 2/3. They place one of their pieces down while flipping over (and moving) one of their opponent's pieces. The first player to create the numerical value of seven with a line of pieces (horizontal, vertical or diagonal) loses.
My intent with this game is to create something:
** With hidden information (a certain % of chance is involved)
** That kids could play as well as adults
** It's something that is relatively quick resolving (game time is less than 10 minutes) with few pieces (18 in total, not counting the board)
The rules are almost written stream-of-conscious; They are not pretty and are not meant to be the final version but, hopefully, they are clear enough.
Thank you for your constructive feedback.
