Slide 5 (1980)

You and your opponent alternately slip chips into the slotted gameboard. Whoever is the first person to get 5 of their color in a diagonal, vertical or horizontal row wins the game. But be careful, Slide 5 can be your downfall, for the gameboard is very changeable... if a row is filled with 5 chips (not all of the same color), a player may insert another chip into that row causing the others to slide down into new positions and to force out the bottom chip. So look every which way before you Slide 5!
