Hoop Stack is a color ring sorting puzzle where you move colorful rings between pegs. Pick up a ring from the top of one peg and place it on another peg — but only if the target peg is empty or has a ring of the same color on top. Sort all rings so each peg holds a single color to win!
1. Tap a peg to pick up its top ring.
2. Tap another peg to drop the ring there.
3. Rules: You can only place a ring on an empty peg or on a peg where the top ring matches.
4. Goal: Every non-empty peg must have all rings of one color and be full.
Use undo freely — it doesn't cost stars. Watch the hint if you're stuck. Empty pegs are your best friend: keep at least one free as a staging area. Plan two moves ahead — sometimes moving a ring up temporarily is the key.
