Stack Control is an Icehouse game of stacking shared pieces. Each player is assigned a color, and there is at least one neutral color in play as well. On your turn, you can stack pyramids of any color, either helping score potential points for yourself or to eliminate rival pyramids. If all your pyramids leave play, you lose! Otherwise, when there are no more moves, if you have more pips worth of pyramids in towers you control, you win. Stack Control combines the shared pieces of Volcano with the scoring mechanism of IceTowers, and bears a striking similarity to Sid Sackson's Focus.
