Our own leaderboards (Score, Depth, Pod and the Daily Dive), livelier whale swimming and small fixes.
Sing to see in the dark. Dive the deep sea, rescue whale calves, grow your pod.
The trench is pitch black. You are a young whale, and you can't see a thing. So you sing. Echo Deep is a calm, glowing deep-sea game about listening. Every song you sing sends out a ring of sound, and for a moment the dark ocean lights up: rocks, glowing krill and lost whale calves calling for help. Then the dark closes in again. Dive as deep as you can, choose when to sing, and bring the calves home. WHY YOU'LL LOVE IT • One-tap sonar: tap to sing, drag to swim. Easy to learn, hard to master • A beautiful underwater world that reveals itself only when you sing, and the deeper you dive, the darker it gets • 60-second dives: beat the clock, quick to start and perfect for a short break • Three hearts to start: every rock you hit costs one, so sing before you swim • Glowshells add time to the clock and make your echoes linger: rocks you reveal stay lit longer for the rest of the dive • Grab hearts for another chance and speed boosts to dive faster and score more • Rescue lost calves: they follow you, multiply your score and join your pod for good • A bigger pod means more breath for longer songs • Four ocean zones: Kelp Forest, Whale Fall, Hydrothermal Vents and The Abyss • Three songs to master: Pulse, Beam and Lure, which pulls krill toward you • Play as 9 sea creatures, each with its own perk: a beluga with longer echoes, an orca that gathers calves from afar, a narwhal that cracks small rocks, a ghost whale that slips through your first hit, plus midnight humpback, manta ray, anglerfish and golden koi. Level the perks up with krill • Earn Pearls from a free daily chest, optional videos and Daily Dive streaks to unlock creatures faster • Daily Dive: the same trench for everyone each day, with its own leaderboard. Perks are off, so it is always fair • One score to chase: meters dived plus krill, multiplied by every calf in your pod, on the high-score leaderboard (plus deepest dive and biggest pod) • Cloud save keeps your pod and costumes safe • Smooth, calm and made for short breaks, with soothing ambient sound • Plays offline HOW TO PLAY 1. Tap anywhere to sing. Your song lights up everything it touches. 2. Drag to swim left and right through the trench. 3. Each song uses one breath, and breath refills slowly, so sing at the right moment. 4. Eat glowing krill for points and breath. Avoid the rocks hiding in the dark: each hit costs a heart, and you have three. Every dive lasts 60 seconds, so make them count. 5. Near the surface you can see everything. Deeper it gets darker, so sing to see. 6. Collect Glowshells to add time and keep rocks lit longer, hearts to heal, and speed boosts to dive faster. The dive ends when the clock or your hearts run out. 7. Find the lost calves and lead them down with you to multiply your score. 8. Beat your high score and climb the leaderboard. A relaxing whale game for fans of ocean games, deep-sea adventures, endless divers and calm one-tap arcade games. Echo Deep is free to play with ads. Rewarded ads are always optional. Creature perks are small, can be unlocked with krill or earned Pearls, and some creatures can also be bought. The Daily Dive is fair: every perk is off, so the daily leaderboard is pure skill.
