Clacks

About Clacks

Stack fast. Train smart. Race your best.

Clacks is a precision cup-stacking arcade built for quick runs, deep improvement, and same-device competition. Tap cups in the correct order, build each formation, then collapse it cleanly while the clock records every hundredth.

RACE COACH

Your run history becomes a private performance model. Race Coach measures recent pace, clean-run rate, consistency, trend, and personal best for each pattern. It identifies the skill most likely to help next, sets a reachable target, and builds a four-block practice session. Every calculation stays on your device.

SIX WAYS TO PLAY

- Quick Stack: choose a pattern and chase a personal best.
- Daily Stack: one deterministic challenge that changes each day.
- Tournament: progress through six distinct opponents.
- Practice: learn the next motion with clear cup guidance.
