I still have my Pegity board from the 60's. It is a 15 X 15 pegboard with four sets of colored pegs. The object is to be the first one to get five in a row. Just like the Line 5 game, I believe. If you play with more people it gets really hard to make a five ina row, plus the unfairness of it becomes obvious when your two opponents or three if playing four handed decide to gang up on you. We didn't play the game much except two handed on occasion. Seemed kind of dead at the time with all the other games that we could chose from (Monopoly, Chess, Battleship, Card games, tag, ditch it ....etc.) Had we thought about modifying it then I'm sure we'dve come up with something. Partners would probably work OK. You could play to help your partner get a five in a row while blocking the opponents. Pente would be an interesting game like that. You'd have to experiment with the play until you got it worked out a little. Three handed would probably be unfair as was Pegity. Three handed games of almost any kind are hard to find that are fair. 2 against 2, or 1 on 1 seem to work best.
