About Unstack Tower
Unstack Tower is a satisfying colour puzzle that challenges you to dismantle a tower of stacked coloured cubes in a specific sequence rather than simply knocking it apart. Each cube must be removed in the right order to progress, which turns the seemingly simple act of clicking blocks into a surprisingly deep exercise in planning and spatial reasoning. The visual clarity of the cube tower and the tactile feel of cubes sliding away in the correct sequence make each successful level feel like solving a small, self-contained riddle. Difficulty ramps steadily, introducing more colours and trickier arrangements as you advance.
How to Play
Study the tower's colour arrangement and identify the correct sequence in which to remove the cubes. Click or tap the cube that should be removed next according to the puzzle's rules. Removing cubes out of sequence may cause the tower to become unstable or trigger a fail state, so think before you click. As levels advance, longer and more intricate sequences demand greater attention and planning.
Tips & Tricks for Unstack Tower
- Scan the entire tower from top to bottom before making your first move to understand the full colour sequence.
- If you feel stuck, work backward from the target end-state to figure out which cube logically must come out first.
- Take your time on levels with many colours — a few seconds of study at the start prevents costly mistakes mid-sequence.
