Bubblarium fills your screen with a beautifully animated underwater world: colorful fish drift past, a dolphin leaps above the waves, crabs scuttle along the sandy floor, and bubbles rise gently toward the surface. Tap any bubble to pop it, or just sit back and watch. TWO WAYS TO PLAY Zen Mode is pure relaxation. No timers, no pressure, no score. The aquarium runs as a living screensaver you can interact with whenever the mood strikes. Pop a bubble, watch the shark prowl, spot the UFO abducting your fish — or just let it breathe in the background. Bubble Rush turns the aquarium into an arcade challenge. Race the clock and pop as many bubbles as you can before time runs out. Combo chains multiply your score. Special bubbles — golden, pearl, danger, and mystery — change the rules on the fly. Watch out for the shark, crabs, barracuda, and UFO; they all have their own ideas about your bubbles. THE AQUARIUM IS ALIVE • Sharks prowl and snap at bubbles, costing you points in Rush • Dolphins leap above the water and dive back in • Crabs scuttle the floor and occasionally grab bubbles mid-swim • A barracuda darts through in a flash • A UFO surfaces and beams your bubbles into the sky • Angelfish, neon tetras, and seahorses drift through it all BUBBLE RUSH FEATURES • 8 difficulty tiers that unlock naturally as your lifetime score grows — from Reef Rookie to Bubble Legend • Golden and pearl bubbles worth bonus points; danger bubbles that punish careless pops • Mystery bubbles that trigger random events: score multipliers, bubble bursts, shark frenzies, and more • Combo multipliers for rapid pops • Game Center leaderboards and achievements • Round summary with stats after every game MAKE IT YOURS! Customize the scene from the menu: toggle creatures on or off, adjust fish count, bubble count, and crab count. Everything is saved so your aquarium always looks exactly how you like it. OPTIONAL ADD-ONS (one-time purchases, all $0.99) • Additional submarine scenery and a sunken shipwreck for the aquarium floor • Game Sub Pack: a navy submarine that patrols during Bubble Rush and fires torpedoes at your bubbles • Torpedo Pack: unlocks upgraded and danger torpedo variants for the game sub • Squid Pack: a squid drifts through your aquarium and hunts bubbles during Bubble Rush All add-ons are optional — the full Zen and Bubble Rush experience is complete with no additional purchase required.
