Endless
The classic game. Place your three pieces, clear lines and chase your best score.
Four ways to play
The classic three-piece block puzzle, plus a hand-built Journey, a puzzle of the day and head-to-head duels.
Journey
Hand-built levels across a reef map.
- Rescue pearls, hit a score or clear set lines
- A piece limit, with stars for pieces left over
- A boss fight every 10th level
- Secret caves unlocked by golden pearls
Daily
One shared puzzle a day, the same for everyone, with a result card to share.
Duel a friend
Send a link. Your friend plays exactly the same pieces as you, and the higher score wins. Bring a reef helper with one special power.
Power blocks
Clearing lines fills your power meter. When it's full, drag the reward straight onto the board.
Bomb
Clears a 3×3 patch with a big bang.
Zapper
Throws lightning down a row and a column at once.
Grow a reef that's yours
Your reef starts empty. At the end of your first game you choose your first reef friend from three. After that, lines you clear in any mode, Journey wins, bosses and secret levels all bring new creatures.
There are 16 kinds to find. Each one also has its own colour, expression and personality, and every one of those comes in four rarities. That makes thousands of combinations. Pick up to six to swim behind your games, and keep the rest in your collection book.
