Description
Hide-and-seek tag under the sea! Octopuses camouflage into coral and sand, free caught friends and escape for 110 seconds; divers hunt them down. Earn shells in matches to decorate your octopus den, and meet 24 real sea creatures that drop by, from clownfish to dumbo octopuses. Share a room code to play online with friends and family, up to 6 players. Playing alone? CPUs fill the empty seats. ■ New: My Den Buy furniture, coral, treasure and wallpaper with shells and place them anywhere, from scallop beds to a sunken pirate ship. 170+ items, counting seasonal items and puzzle rewards. Your octopus sleeps, sits and plays with what you place. The room follows your clock from day to night. Save up shells to expand to 3 rooms, each with its own walls, floor and decor. Widen any room up to 2x and swipe to look around. Snap a photo to share. Shells come from every match and are never sold for money. During events like Halloween and Christmas, watch ads for seasonal decorations. ■ Creature Book Sea creatures visit depending on what you place: clownfish for anemones, garden eels for a sandy floor. Some come only at night, and the sea angel only in winter. New visitors join your Creature Book and leave shells as thanks. Invite anyone you've met, or send them home. ■ Puzzle Festival (limited time) During a festival, matches earn up to 3 puzzle pieces a day, plus 2 in Golden Time (21:00-21:05, device time). 9 pieces finish a puzzle and unlock a limited item or hat; finish all 4 for a grand prize. When it ends, pieces in unfinished puzzles are gone. Rewards are yours to keep. Pieces can also be bought; a bought piece always fills one you don't have yet (no luck involved). ■ How a match works 3 octopuses vs 3 divers; your role changes each match. Sit on coral, rocks or sand and your color shifts to match. Camouflage burns energy, so you must leave your spot to eat fish. Squirt ink or dash to escape. ■ Free your caught friends Stay next to a caught friend for 2.5 seconds to set them free. Divers must guard what they catch, so every capture becomes a standoff. ■ Tricks and dangers Close your eyes to vanish for 10 seconds, or ride a sea turtle. A spear hit catches only 1 in 4 times. Sharks bite both sides. ■ Play alone or with up to 6 players - "Play Online" matches you with one tap; share a room code to play with friends, even just 2 - Ratings for octopus and diver, 4 seas plus seasonal seas, and 3 daily missions ■ Looks, not power Forms, colors, hats and den items only change looks. Tiny and Mini Squid are a little harder to spot. Ink and the Speargun stay at one use per match, even with a subscription. ■ About ads Ads never interrupt a match. A short ad may appear after results every few games; the Octopus Pass removes them. You can also choose to watch ads for items or double shells. ■ Monthly subscriptions (auto-renewing) and other purchases - Ink Monthly, JPY 280/month: use Ink once every match without watching an ad - Speargun Monthly, JPY 280/month: use the Speargun once every match without watching an ad - Octopus Pass Monthly, JPY 560/month: both of the above, plus no ads after matches. You also receive looks (Slender form, Halo hat) on your first purchase, and you keep them even after cancelling - Items can be used ONCE PER MATCH. Not unlimited. Your strength does not change - Payment is charged to your App Store account when you confirm the purchase - Renews automatically at the same price unless cancelled at least 24 hours before the period ends - Cancel any time in Settings > Apple Account > Subscriptions - If you already bought the one-time versions, they keep working without a subscription - Prices shown are the Japanese yen base price; you are charged the equivalent in your local currency. - Also available: puzzle pieces (consumable) and the Golden Octopus Statue den item (one-time).
