Bottomless

One summer dive. One enormous wave. One very missing swimsuit.

In Bottomless, a boy searches the ocean for his lost trunks—and finds just about everything else. Tap left and right to swim through bright reefs, sunken wrecks and the midnight trench. Keep your rhythm, watch your air and decide when a risky detour is worth it.

ADVENTURE: GO DEEPER, ONE DIVE AT A TIME
Every attempt starts at the surface. Keep the salvage you collect, even when your dive ends, and spend it on more breath, stronger strokes and tighter turns. Buy permanent flashlight upgrades to see farther into the dark.

CASUAL: A FRESH BUILD EVERY DIVE
Start with 60 seconds of air. Discover equipment to refill your breath and improve your swimming for this run. Walls bounce you back, obstacles cost air, and creatures end the dive. Keep your coins for a separate cosmetic swimwear collection.

AN OCEAN WITH A MIND OF ITS OWN
Weave past swimming fish, pulsing jellyfish, lunging eels and hungry sharks. Fish can slow you down, stings burn through your air and a shark can end your dive. Optional air pearls, slipstreams and shields can turn a good attempt into a new best.

FIND EVERYTHING EXCEPT YOUR TRUNKS
Recover 24 absurd artifacts, including an antique toaster, a mossy bowling ball and a microwave that somehow still works. Treasure milestones are claimed once: your next dive must go farther to find the next one. Discoveries do not refill your oxygen.

A LITTLE MORE DIGNITY
Choose a cardboard box, flamingo float, wooden barrel or kelp skirt. Outfits change your look, never your swimming stats. The character is always covered by bubbles or an outfit.

SIXTY REASONS TO KEEP DIVING
Earn permanent medals for discoveries, skill and depth records—including comparisons with famous towers, lakes and the Titanic wreck. Tap any medal to see its challenge and progress.

• Two-thumb momentum swimming made for portrait play.
• Four illustrated ocean layers and a chibi cartoon cast.
• A comic opening for new adventures; Continue gets you straight back to diving.
• Offline gameplay and local progression, with no account required.
• Separate music, sound, vibration, reduced-motion and discovery-animation settings.

ADS AND AD-FREE
Adventure offers optional ads to double the coins from a completed dive. After three completed Adventure dives without seeing an ad, a run-end ad appears when available. Casual also has run-end ads.

The permanent Ad-Free Salvage purchase removes ads in both modes and automatically doubles Adventure coins, even offline. It does not multiply Casual coins, and bonuses never stack. Unavailable ads never block another dive.

Progress is stored on your device. There is no cloud save or online ranking. Store purchases and rewarded ads need an internet connection.
