Let's Dance Robot — part dance party, part physics playground, now with something to earn. Name your robot and watch it bust four custom dance moves in Classic Mode, each in its own room: a neon alley, a rooftop sunset, a cold arena under the stars, a violet room with a mirror ball. Then flip to Live Mode and run the show: charge up your robot, feel the beat, and release right on time to launch it flying. Nail the timing for a PERFECT — bigger throws, wilder caroms, way more points. Every crash earns rank. Climb ten ranks from Scrap to Legend and unlock a new look at every step: paint finishes like Gunmetal, Neon, Ember and Chrome, and trails your robot leaves in the air — vapor, comet, stardust, prism. New unlocks equip themselves; swap them any time in the Workshop. • Live Mode: charge-and-throw physics with beat-synced timing • Ten ranks, nine unlocks — finishes and trails you earn by playing • The Workshop: your rank, what's next, and everything you've unlocked • Time your release for PERFECT and GOOD bonuses; faster tracks score bigger • Today's Fling: one shared track a day, a daily leaderboard, and a streak for coming back • Game Center leaderboards for total crashes and best single fling • Four Classic dances, each with its own music, vibe, and room Free, friendly, and endlessly bouncy. What will your robot look like at Legend?
