Gameplay in Stack Columns is mostly identical to that seen in "regular" Columns, however with a stronger focus on competitive play. Stack Columns introduces the Crush Bar from Columns III, now called the "Stack." If the beginner mode is not chosen, the Stack is built up after combos. Pressing when a stack is present allows you to "attack" an enemy, causing that pile to rise close to the top. The higher the stack, the more damage is done.
