Unwind your mind and sharpen your wits with Hoop Stack, the addictive color-sorting puzzle that blends logical planning with spatial harmony. While the task seems simple: sorting vibrant rings onto their matching pillars. Every move becomes a tactical decision as the colors multiply and the stacks grow deeper. From beginner-friendly puzzles to mind-bending multi-layered challenges, you’ll need to think three steps ahead. Use empty pillars as strategic buffer zones and master the sequence of movement to achieve a perfect sort. With its crisp, minimalist aesthetic and a soothing, “one-more-try”rhythm, Hoop Stack is the ultimate way to activate your brain during your morning commute or evening wind-down. Are you ready to claim the title of Hoop Sort Master?

Your ultimate goal is to reorganize the spectrum. You must sort every colored ring until each pillar holds only a single, uniform color. Navigate through a massive library of levels, optimizing your movement paths to clear the board and unlock increasingly complex spatial riddles!

The Logic of the Stack

• The Difficulty Curve: Higher levels introduce more colors and chaotic initial layouts, requiring deeper foresight.
• Victory Condition: A level is cleared only when every ring on the board is sorted by color, with each pillar containing a matching stack.
• Placement Restrictions:
  • You can only place a ring on an empty pillar or on top of a ring of the exact same color.
  • Each pillar has a strict capacity limit. Once a pillar is full, no more rings can be added until space is cleared.
• Movement Rules:
  • Only the topmost ring of any stack can be moved.
  • Rings trapped at the bottom must wait for the upper layers to be relocated before they can be played.

Game Controls

Mouse/Touch: Click or tap a pillar to select the top ring, then click the target pillar to drop it.

The layout is getting too complex! How do I find the best path?

Don’t let the chaos overwhelm you! The best strategy is to isolate the easiest color first. Find the color with the most rings already grouped or the one that is easiest to reach. By completing one solid pillar early, you free up a vital “buffer pillar” that makes managing the remaining colors significantly easier.

What should I do if all my pillars are full and I’m stuck?

Strategic pillar management is key. Look for a pillar that is nearly finished and prioritize completing it to “lock in” that color. Always try to keep at least one pillar relatively clear to act as a temporary transition point for mismatched rings.

I made a wrong move and ruined my sorting order. Is it game over?

Absolutely not! Hoop Stack is a zero-stress experience. There are no move-count penalties, so you can simply move the misplaced ring to an empty pillar and re-plan your route. Take a second to observe the whole board before your next move—patience is your greatest tool.
