About the game

Stack fast. Beat your time. Beat your friend.

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.
