Dive into Bubbly. Bubbly is an underwater bouncy arcade side scroller where every tap can help you and Bubbly win! Help your friendly Bubbly float through shimmering submerged obstacles and random gaps. Play for 30 seconds or 30 minutes of family friendly fun. Tap quickly to help Bubbly battle gravity. In "Rises" mode, you help push Bubbly down to pass through the obstacles. It's the opposite of normal gravity. Looks easy, but it is surprisingly hard! Or switch to "Drops" mode for a wild twist where Bubbly acts like your normal gravity world. You can adjust gravity strength for more float or more pull. And adjust the obstacle gap sizes to set the perfect challenge. You also get to set the number of obstacles that will randomly appear to make the game super short or super long. Control Box Features: - Pause / Resume to take a break - Switch between music tracks—or play in silence under the sea - Enable Autopilot AI where Bubbly tries to play the game with its own AI control. In AI mode, you can play along to help Bubbly, or just watch and enjoy. - Music & Atmosphere - Two original background tracks create the vibes—relaxing or intense, depending on your run. - Modes: Normal and Bubbles. Bubbles mode gives you 5 shields and spawns bubbling shield restore orbs. - Accessibility & Customization - Gravity Bubble is built with accessibility labels. Works in both portrait and landscape, and looks great in Dark Mode. - Challenge Yourself Start easy and widen the gap, or crank it down until every passage feels impossible. Earn your win screen, share your victory, and keep experimenting with new settings. - Why does everyone like this game? Quick, satisfying play sessions Smooth game play—no lag, no ads, no nonsense Whether you’re sneaking in a minute of fun or chasing your longest survival streak, Bubbly delivers pure, tap-happy satisfaction.

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.

Verdict
The clearest difference is ads: BubblyAI at none against Chain's shown. Chain's advantage is update cadence (weekly vs every 3 months) and iOS requirement (18.6 vs 27.1). On price, in-app purchases and device support there is nothing between them.
