TIME NEVER STOOD A CHANCE. Cuckoo Boom is a vintage-styled reflex arcade for anyone who's ever wanted to kill time instead of watching it kill them. Tap the seconds. Crack the minutes. Hold down the hours. Feels simple — until the second you just crushed splits into two, and comes back doubled. Time doesn't go down without a fight. Built with the instincts of the cabinets we grew up on: no tutorial, no hand-holding, just reflexes, a streak that rewards precision, and a scoreboard that remembers everything. If you've been killing time since before "killing time" needed an app for it, Cuckoo Boom is yours. HOW TO PLAY • Tap the Second — one hit, gone. Fast, small, relentless. • Crack the Minute — three hits, cracking visibly with every one. • Hold the Hour — keep your finger down and watch the ring close in. • Let one escape and you lose a life. Miss a tap and nothing happens — hesitation costs you more than a bad shot. WHAT MAKES IT DIFFERENT • The Second splits. Closing out every world, the enemy you thought you understood breaks into two smaller ones coming at you at once. Nothing stays simple for long. • Streak multipliers reward speed and precision — the faster your run, the more every kill is worth. • Chain a big enough streak and earn a BOOM: a screen-clearing sweep that turns a losing stage into a comeback. • 16 stages across 4 escalating worlds, each with its own color and its own pace. Built to punish hesitation, not memorization. A vintage arcade feel, built for the pockets of time you actually have — the commute, the waiting room, the five minutes before a meeting starts. Cuckoo BOOM. Kill time.
