Drop a disc into one of seven columns. It falls to the lowest empty spot. Line up four of your discs across, up and down, or diagonally before the other side does.
■ Start in one tap
- Play now opens a new game with your last settings, straight away.
- No sign-in and no setup before the first game.
■ Play the computer, or a friend
- Six computer levels, from Beginner to Master. Each level is tested against the next so they stay in order.
- Two players can take turns on one phone.
- The computer thinks on your device and moves quickly. No internet needed.
■ Fair turns
- Moving first is an advantage, so by default who goes first switches every game.
- You can also choose to always go first, or let the computer go first.
■ See what happened
- The last disc played has a small dot.
- When the computer blocks your four, the line under the board says so.
- The winning four are joined with a line, and the result says where and which way.
■ Play your way
- Press a column to see where your disc will land, slide to another column, and lift to drop. Lift outside the board to cancel.
- Unlimited undo.
- Hints that suggest a column.
- The game is saved after every move. Continue where you left off.
- Wins, draws, losses and streaks for each level, plus a list of your last ten games.
- Light and dark discs differ in brightness and pattern, not only colour.
- Works in portrait and landscape, and in dark mode.
■ Rules
- Seven columns and six rows. Turns always alternate.
- Four or more in a row wins at once.
- If all 42 spots fill up with no four in a row, it is a draw.
Drop discs, line up four. Play the computer at six levels or a friend offline.
