4 in a Row vs Computer
About Four in a Row
This page drops you straight into a single player game of Four in a Row against the computer at Normal difficulty — a solid club-level opponent that blocks obvious threats and punishes careless play. It is a free Connect 4® style game you can play alone, any time, with nobody to wait for.
Too easy or too hard? Hit Change Mode after a round to pick Easy (a rookie that wanders and misses blocks) or Hard (a mastermind that searches six moves deep and rarely loses to a single threat). Every bot game uses a fresh seed, so the same opening will not always get the same reply.
How to play
- • You play red and move first — tap a column or press keys 1–7 to drop a disc.
- • The computer replies after a short think; its discs are gold.
- • Line up four of your discs across, down, or diagonally before it does.
- • Play Again starts a new round and keeps score; the first move alternates every round.

Frequently asked questions
How hard is the computer opponent?
Normal (the default here) plays like a decent club player. Easy is a beginner that misses blocks. Hard uses a minimax search six moves deep with a strong evaluation — it will see most double threats coming, so you have to build them quietly.
Can I beat the Hard AI?
Yes, but you need a plan: take the center column early, build threats on odd rows when you are red, and aim for two winning squares stacked in the same column. The strategy guide walks through each of these.
Is 4 in a Row vs computer free?
Yes — free, no download, and no account. It runs in your browser on phones, tablets, and computers.
Can I switch to playing a person?
Any time. Choose Change Mode to play two player on one screen, or start an online game and invite a friend with a link.
