COOKIE STACK Stack Game
COOKIE STACK is a free browser stack game where you drop sliding cookies one by one to build a 3D tower up to the moon. No download, it starts right in your browser on phone or PC.
A new cookie slides back and forth next to the top of the tower. Tap the screen or press Space and it drops right there, and only the part that overlaps the cookie below stays. The overhang crumbles off and falls, sticking to a ledge or the ground. Miss a little and the cookies get narrower, miss completely and it is GAME OVER.
Line it up exactly for a PERFECT and neon sprinkles burst from the cookie. Butter and cocoa cookies alternate layer by layer, topped with neon icing in pink, yellow, green, blue and more. Every time you clear a stage a cream layer drops onto the tower and your cookie goes back to full size.
There are 10 stages and 190 floors. You start above the rooftops and climb past sparrows on power lines, under and above the clouds, hot air balloons, a sunset, a rainbow bridge, a starry night and outer space. On top of the last stage waits a chocolate chip cookie moon. The icing glows brighter as night falls, and the marimba music is made in code.

Frequently asked questions
My cookies keep getting narrower. Can they grow back?
Yes. Every PERFECT drop makes the cookie a little wider, and keeping a PERFECT streak of three or more makes it grow faster. It never gets bigger than the starting size. In Hard mode a single PERFECT does not grow it, only a streak of three or more does.
If my tower falls, do I start over from the bottom?
No. You only redo the stage you fell on, from its first floor. Stages you already cleared stay, and next time Continue starts you on that stage. Progress is saved separately for Easy, Normal and Hard.
What is the difference between Easy, Normal and Hard?
All three have the same stages and floors. The sliding speed and how close counts as PERFECT are different. Normal is 1.25 times and Hard 1.55 times faster than Easy, and both speed up more with every floor. The width you win back with a PERFECT is smaller on harder modes.
What is the white layer between the cookies?
That is a cream layer, the sign of a cleared stage. When you finish a stage it drops onto the tower, and from there your cookie is back to full size for the next stage.
Does it end?
Yes. Finish the 28 floors of stage 10 and the cookie moon above opens its eyes as fireworks go off. Then a result card shows your floors, PERFECT count, best streak, falls, time and title, and you can save or share it. There is no endless mode after the ending.
