Stack falling pairs and run a single-color cable from a bulb to a battery. The moment they link, the whole circuit sparkles and pops! ■ How to play • Red, blue, green and purple cables, plus bulbs and batteries, fall in pairs. Each color has its own shape mark, so they're easy to tell apart. • Tap to rotate the pair, swipe sideways to move, swipe down to drop! • Cables of the same color join up on their own. No lining up wire ends! • When a one-color line runs from a bulb to a battery, the line, bulb and battery all pop! • When the tiles above fall and link a new line, chain pop! ■ Bigger pops • 2 batteries on one line is ×2 power, 3 is ×3! • Stack other colors on top of your circuit to set up big chains. • Obstacles rise from the floor. Lit bulbs break the ones nearby, and more batteries reach farther! ■ Cute and cozy • Smiling bulbs and batteries, star sparks and a bouncy soundtrack • A one-pair tutorial • Amber, Mint, Rose and Ice bulb skins • Calm mode (less shake and flash), sound and haptics settings • Game Center leaderboards Remove ads + the Aurora skin is a one-time purchase (not a subscription).
