Coffee Stack turns a fast-moving conveyor into a caffeine-fueled gauntlet. You ride the platform track, scooping up dixie cups, building cup sets, and flooding them with vivid green coffee as your tower grows. Every grab counts. Miss one and the stack wobbles; nail a clean line and the pile looks glorious. But the track bites back. Traps snap, gaps nudge, and grabby free hands swipe at your hard-earned cups. The belt don't forgive, lose too many and the run fizzles. Reading the rhythm is everything: you thread hazards, keep the balance, and guard that stack like it's sacred. Simple to learn, spicy to master. Clean feedback, a smooth flow, and a pace that sprints from cozy to "oh no, oh no" in seconds. You're not just hoarding cups you're crafting a rolling caffeine monument, one clink at a time. Hit Play and start stacking.
