What is Stack Up?

Stack Em Up! is a casual single-player puzzle game where your goal is to connect stacks of the same color to combine them. By chaining same-colored stacks, you build longer stacks; you try to reach stacks of length 10 or more.

It’s stylised and simple in controls.

There are many levels that get progressively more challenging.

How to play Stack Up

Tap on a stack: You select a stack by tapping it.

Connect with other stacks of the same color: Once you select a stack, you try to link it to other stacks of the same color to form a longer chain.

Form stacks / chains of 10 or more: One of the objectives is to make long stacks (length ≥ 10). Bigger stacks give more “score” / help you meet level-goals.

Watch your moves: You have limited moves or constraints per level; you must achieve the objective before you run out of moves, or before you run out of opportunity.

Progress through levels: Levels get harder as you go, likely adding complications (more colors, tricky board layouts, etc.).
