Stackdom: Color Sort Puzzle

Sort every color, stack blocks from big to small, and beat the clock!

Stackdom is a fast spatial puzzle where stacked blocks stay on the board, so every move changes the space you have left.

Move colorful blocks around the grid, group matching colors and build each stack from largest to smallest. The twist is that stacked blocks never disappear, so every move changes the space you have left to solve the rest of the level.

Simple rules make Stackdom easy to pick up, but tighter spaces, taller stacks and more colors quickly turn each level into a clever spatial challenge.

STACK BY COLOR
Every block of the same color belongs together. Move pieces around the board, bring matching colors together and build complete stacks one step at a time.

BIG TO SMALL
Stacking order matters. Larger blocks belong at the bottom, with smaller blocks stacked on top. Build in the wrong order and you may run out of space for the pieces you still need to place.

STACKS STAY IN PLAY
Stacked blocks do not disappear. Every stack remains on the board, so solving one part of the level can make another easier — or block the space you were planning to use. That makes every move count.

BEAT THE CLOCK
You know what the finished board should look like. The challenge is finding the right sequence of moves before time runs out. Early levels give you plenty of room to learn the rules, while harder levels demand faster decisions, better planning and smarter use of limited space.
