REFLEX-4

REFLEX-4 is basically the game of Connect Four, but there's one difference.  You can only choose a column to drop your chip by following an arrow that moves above the game board; your piece will fall into the slot that the arrow is above when you press the space bar.  It can be challenging at first, but with practice it gets easier.  The game has an easy-to-use and pleasant user interface, sound effects, and keeps track of stats too.
