Nut Stack Bench app analytics for September 11

Nut Stack Bench is a calm portrait sorting puzzle set on a bright Nordic workbench. Tap a source bolt to lift only its top nut, then tap an empty bolt or a stack with the same top color. Keep every bolt under its four-nut height limit and finish each work order with complete monochrome stacks. Solve 24 authored layouts that grow from three-color introductions to six-color master fittings. Replay completed orders, improve your best move count, undo or restart freely, and use optional solver hints when you want help. Normal play always works with zero Washers. Earn Washers from completed orders or tap the clearly labeled Home AD tag for a bounded Washer pack. The reward is granted only after the rewarded callback succeeds.
