Hi-Bol is a portable skee ball dexterity game for any number of players. The game folds up and seals with velcro; once opened a small ramp flips out while two straps hold it somewhat less than open. Set it down and you're ready to go. Increase the distance to increase the challenge. The game includes 7 wooden balls (6 white; 1 red); the red ball scores double so when to use it is always a tactical decision on the part of each player.
