Cove is a cozy little corner of the ocean packed with relaxing puzzles. Four games in one, so you never run out of something to play. Sink in, unwind, and grow your reef. FOUR PUZZLE GAMES, ONE COVE • Tide Blocks: drag and fit blocks to clear lines. Simple to learn, very hard to put down. • Reef Sudoku: classic number logic in easy, medium and hard, with pencil notes for the tricky ones. • Tide Pool: merge matching tiles, fill reef orders and watch your pool grow. • Word Tide: crack a fresh five-letter word every day, or play practice words as long as you like. RESCUE THE REEF Every line you clear sends a bubble to the tide. Fill the tide and a sea creature hatches and swims into your reef. Feed your creatures and they grow. Your reef is always there waiting, and it gets a little livelier every time you play. COLLECT SILLY SEA STICKERS Earn shells and nets as you play, then haul them in to see who you caught. Fill a seasonal album of charming sea characters, from the Rockstar Puffer to the Narwhal King. There's always one more to find. MADE TO RELAX A calm ocean palette, gentle music and satisfying little sounds on every move. Turn music, sound or vibration on and off whenever you like. Cove plays nicely with your own music and podcasts too. WHY YOU'LL LOVE IT • Four full games in one app • No energy timers. Play as much as you want • Daily streaks, daily quests and a new daily word to come back for • Plays offline, no account or sign-up needed • Free to play Dive in. The reef is waiting.
