## What is Nut Stack?

Turn a colorful mix of nuts into perfectly sorted stacks. Nut Stack is a nuts-and-bolts color sorting puzzle with glossy metal pieces, satisfying movements and clever challenges.

TAP. MATCH. STACK.
Tap a bolt to pick up its top nuts, then tap another bolt to move them. Match the color on top or use an empty bolt with enough space. Bring each color together and finish the board, one satisfying stack at a time.

EASY TO START, MORE TO DISCOVER
Begin with simple color puzzles and work your way through hundreds of levels. As boards grow and new obstacles appear, every free space becomes part of the solution. Look ahead, make room and find the right order.

A FRESH TWIST ON COLOR SORTING
Uncover hidden colors, work through stone shells and meet new obstacles as you progress. Different layouts keep each puzzle feeling fresh.

A HELPING HAND WHEN YOU NEED IT
Unlock useful boosters as you play. Undo a move, shuffle things up or add an extra bolt to create space for your next idea.

ENJOY THE LITTLE DETAILS
Brightly colored nuts, polished steel bolts and tactile sound effects make every move feel satisfying. Play a quick puzzle during a break or settle in for a longer sorting session.

Your next perfect stack is one tap away.
