Stack Ball Unblocked — Play Free Online

Stack Ball on this page loads a Unity build whose own files name it Stack Ball 2 and credit a company called DMA, packaged for the GameDistribution network. It is a tower-smashing game played in a tall portrait frame: a light blue ball bounces on top of a twisting stack of slabs wrapped around a white pole, and your job is to drive it all the way down to the base.

What you are looking at

Each level is one tower. The slabs are coloured in two kinds: bright yellow pieces you can break and black pieces you must not touch. Because the stack twists as it goes down, the yellow and black sections spiral around the pole, so the colour under the ball can switch from one slab to the next. At the bottom sits a round base with a checkered rim, which is where a level ends.

A bar at the top of the screen shows the current level number on the left and the next one on the right. A settings button sits in the lower-left corner of the start screen.

Controls

The start screen reads "Touch to play". Press and hold the mouse button (or your finger on a touch screen) and the ball stops bouncing and slams downward, cracking through each yellow slab it lands on. Let go and it goes back to bouncing in place on whatever it is standing on.

If the ball comes down on black while you are holding, the run ends. The screen dims, shows "Game Over!" and asks you to touch again to restart the tower.

Playing it well

• Hold only while yellow is below the ball. With the colours spiralling, a safe stretch can give way to black after just a few slabs.
• Release early rather than late. Bouncing in place costs nothing, while one late release ends the level.
• Watch the spiral, not just the slab under you. Following the twist of the yellow band lets you see the next safe window coming.
• Expect the black share to change from tower to tower. Some stacks give you long yellow runs, others leave only short gaps.

About the build

The game files also contain a combo circle and code for switching a bonus on and off, though the first towers do not explain them. On the opening tower the progress bar runs from level 1 to level 2.
