Connect Six: Six in a Row

Connect Six is the pure strategy game you can learn in a minute and think about for years. Place your stones on the board and be the first to line up six.

THE WHOLE RULE
Black places one stone to open. From the next turn on, each side places two stones per turn. Connect six or more of your stones in a row — horizontally, vertically or diagonally — and you win. That is the entire game.

Two stones per turn is also what makes Connect Six fairer than five-in-a-row. In gomoku the first player is so far ahead that tournaments add forbidden moves and swap rules; Connect Six fixes it with one line — black opens with a single stone. Nothing else is needed.

PLAY AGAINST A REAL AI
Four levels. Easy is a friendly place to learn the shapes. Normal punishes loose moves. Hard looks ahead. Expert reads the threats one turn ahead and will not hand you the game. The AI runs on your device, so there is no waiting on a server.

Choose your board before you start: 13×13, 15×15 or 19×19. A smaller board leaves fewer places to run, so threats meet sooner.

310 PUZZLES
• Daily puzzle — one position a day, and a streak that survives a missed day
• Puzzle rush — how many can you solve in three minutes
• My mistakes — puzzles built from your own lost games, at the exact turn you missed the defence
Three kinds: finish the line, stop the win coming next turn, or build a threat that cannot be blocked.

21 BADGES
Bronze, silver and gold across seven families — win streaks, daily streaks, puzzles solved, rush scores, games played, wins against Hard and Expert, and winning on all three board sizes.

TWO PLAYERS, ONE DEVICE
Pass the phone. No AI, no account, no second install.

SEE WHY YOU WON — OR LOST
When a game ends the board stays right where it is, and the six stones that decided it are highlighted. Replay any finished game stone by stone, or take back your last turn while you are still playing. Stats keep your win rate, your streaks and your record at each level.

EVERY MATCH IS KEPT
Finished games go to your History with the final board, the result, the difficulty and how many turns it took. Up to 50 games, stored on your device only.

NEVER MISPLACE A STONE
Tap once to preview a stone, tap the same spot again to place it. Undo any selection before your turn is committed. Pinch to zoom into a crowded corner and drag to look around the board.
