Clacks

Stack fast. Beat your time. Beat your friend.

Clacks is a hand-drawn cup-stacking arcade. Tap cups in the right order, watch them snap into place with a satisfying CLACK, then unstack them back down. Beat your time. Beat your daily best. Beat six mascot opponents in a tournament.

Game features

• Three real cup-stacking patterns: 3-3-3, 3-6-3, and the full Cycle chain. Each pattern uses the descriptive notation that any cup stacker recognizes.
• Six mascot opponents drawn from a small cast of friendly faces: Pip the eager kid, Doc the methodical builder, Gran the sneaky grandma, Bolt the precise robot, Pup the speedy dog, and Goof the cup-dropping clown.
• Five play modes: Quick Stack to set personal records, Daily Stack with a shared worldwide pattern that rotates at midnight UTC, Tournament knockout against the six mascots in sequence, Practice mode with hint highlights that show the next cup, and Local 2-Player split-screen so two people can race on a single device.
• A hand-drawn cardboard aesthetic. Every cup is drawn with a loose ink line and a small wiggle so the row of cups feels well-loved.
• Procedural marimba soundtrack with a light drum kit. The music speeds up during the final cups of every run so the finish always feels like a sprint.
• All sounds and music are synthesized on device. There are no audio files in the binary -- the clacks, bonks, and cheer chords are generated procedurally each time they play.
• Local records for personal best by pattern, daily best, and tournament progress.
• Twenty hand-curated achievements covering target times, daily streaks, tournament wins, mascot match-ups, and a few small surprises.
• On-device data only. SwiftData keeps your run history, daily attempts, tournament progress, and achievement unlocks locally.
