Up-stack every pile into a pyramid, then down-stack them all back, as fast as you can.

• Swipe UP ↑ on the glowing pile to build it up.
• Swipe DOWN ↓ to bring it back down.
• Go in order, left to right (or start from the right end and go right to left).
• Bigger piles take more swipes: a 3 takes 1, a 6 takes 2, a 10 takes 3.
• Wrong pile or wrong direction = fumble: +0.50s and the cups wobble.
• The clock starts on GO and stops when the last cup lands.

The Cycle: 3-6-3, which down-stacks into 6-6, which down-stacks into 1-10-1, which finishes back in 3-6-3.

The grey bar is your personal-best ghost. Beat it!

Every cup is one press, with the correct hand. Tap the LEFT or RIGHT pad (or the left/right half of the screen; F/J or ←/→ on a keyboard).

• Pick your start hand above the stage list. Right: you lead with your right hand and work left to right (how most right-handed stackers do it). Left: everything is mirrored, so you lead with your left hand and work right to left.
• The glowing spot shows the next cup. Cups on the side you start from are your start hand's, and cups on the far side belong to the other hand.
• A cup in the middle (tops of pyramids, single cups) goes to the hand you didn't just use, so you keep alternating.
• When signs are on, an L/R badge floats above the pile you're working on (always on top, never hidden by cups), and the pad you need glows. "Blind" stages take both away.
• Each pile has a wobble meter. Cups higher up shake it more, and so does going too fast. Over the top and the pile topples: +1.00s and you rebuild that pile.
• Wrong hand = a slip: the pile shakes and your hands freeze for a moment.
• Piles go in order from your starting side. "Mix-up" stages jumble the order, so follow the glow. "Back to front" stages run the piles the other way from usual. In "Sudden death" stages, one topple ends the run.
• Beat the stage times for ★, ★★ or ★★★. Stars and bests count for the stage whichever hand you start with.

This works like a real competition timer. It's on for Hands mode and off for Swipe mode by default; switch it with the ⏱ button above the stage or event list.

• Put both thumbs on the two pads at the bottom. The light goes red, then green after half a second.
• The clock starts the moment you lift a thumb. Lift while it's still red and it's a false start, so just try again.
• Stack as normal. When the last cup is done the clock keeps running until you slap both pads at the same time.
• On a keyboard, hold F and J (or ← and →).
