onlinegamesbrowser.comHow to play
The board stands upright, 7 columns wide and 6 rows tall. On each turn a player picks a column, and the disc drops until it rests on whatever is below. You are red; the other side is yellow.
- Under Play, choose Vs computer or 2 players. Against the computer, pick Easy, Medium or Hard.
- Tap a column to drop your disc into it.
- Connect four of your own discs in a straight line, horizontally, vertically or diagonally.
- If all 42 spaces fill up with no line of four, the game is a draw.
- The score keeps adding up until you leave, and the first move swaps each game.
Controls
- Touch or mouse: tap or click a column.
- Keyboard: number keys 1 to 7 pick a column, or select one with the arrows and confirm with Enter.
- New game empties the grid.
Tips
- Take the middle column early. More lines of four pass through it than through any other column.
- Before every move, look for the other side's lines of three and block any with an open end.
- Check the space under where you're about to play. Your disc can hand them the spot they need just above it.
- Set up two threats at once that need different spaces. They can only block one.
FAQ
How strong is the Hard level?
It searches 7 moves deep, favors the center, and blocks your lines of three while building its own. A double threat can still beat it. Medium searches 4 moves deep, and Easy makes a random move about half the time.
What's the best first move?
The middle column. It's part of more possible lines of four than any other column.
Can we play side by side?
Yes. With 2 players selected, red and yellow alternate on one phone or computer, and the tally runs for as long as the page stays open.
Can I play four in a row at school?
Four in a row needs no install and no account, so it opens in any up-to-date browser, Chromebooks included. A school filter can still block the site, and if it does, only the school's IT team can allow it.
