Please avoid placing boxes on blue ones, otherwise, the game will be over. Also, you can compete with the whole world through Game Center Leaderboard. Can't wait to see your score.
Chain

Chain Balls is a fast, satisfying chain-reaction puzzle. Tap once to drop a white starter ball. Watch it expand, collide with the bouncing coloured balls, and set off a chain that ripples across the screen. Time it right and every ball explodes, time it wrong and you'll leave too many behind. SIMPLE TO LEARN One tap. No tutorial required. The physics do the rest. TWENTY HANDCRAFTED LEVELS Normal mode eases you in at 33% and ramps up to 80% of balls required. Twenty levels: each one a new puzzle in how many balls you need to catch. HARD MODE - UNLOCKABLE Beat all 20 Normal levels to unlock Hard Mode: tighter targets (50% → 94%), double the score multiplier, and the same satisfying chain reactions at a whole new level of difficulty. GAME CENTER Compete on the global leaderboard with your total score across the full run. Collect seven achievements - from your first chain to half a million points. LOOKS AND FEELS GREAT Smooth 60fps physics, animated gradient backdrop, satisfying haptic feedback on every chain, and seven distinct pop sounds that play in the order of your chain depth. SETTINGS THAT RESPECT YOU Toggle sound, haptics, and a Reduce Motion mode that freezes all decorative animations without touching gameplay.
