What is Four in a Row?
Four in a Row is a digital board and logic game created by Bloob. It updates the classic connection format by letting you compete against multiple opponents on a shared vertical grid. Instead of restricting matches to two participants, games can include extra rivals competing simultaneously. The core loop centers on dropping coloured pieces into columns to align a set sequence before any rival completes theirs. The title runs directly in modern web browsers without requiring downloads or software installation.
Key features
- Flexible win conditions: Match settings allow players to adjust the required connection length up to six pieces in a row.
- Multi-opponent matches: Support for matches with more than two participants introduces chaotic multi-sided board states.
- Multiple match types: Play casual rounds against automated computer bots, host friend sessions, or face worldwide opponents.
- Cross-device controls: Fully compatible with both mouse clicking on desktop and touchscreen tapping on mobile devices.
- Flexible screen orientation: Plays smoothly in both portrait and landscape screen orientations.

Match configuration and win rules
Players can customize round parameters prior to starting. Standard rounds require forming a continuous sequence of four tokens horizontally, vertically, or diagonally. Custom configurations allow adjusting the victory condition, with support for connecting up to six pieces in a row. When multiple opponents share the board, every placement shifts board priority, requiring players to track several threatening lines at the same time.
Tips and strategy
- Prioritize center columns: Center slots provide the highest number of potential horizontal and diagonal connections across the board.
- Track multiple threat paths: Watch diagonal lanes carefully, as opponents frequently build diagonal alignments that go unnoticed until too late.
- Counter immediate threats first: Blocking an opponent who sits one disc away from completing their sequence must take precedence over extending your own line.
- Anticipate subsequent turns: Avoid dropping a disc into a slot that grants the next player an immediate winning drop on top of yours.
