Against the computer or a friend
Board games are the family where you are playing a person or a program rather than a difficulty curve. The opponent has a plan, and the game ends when one of you executes it.

What board actually asks of you
Four in a Row is the anchor here, and the opponent is genuinely adversarial: it looks several moves ahead, so it does not lose to the threat you set up two turns ago and it does punish the double threat you did not see. That changes what losing means. In an arcade game you lose to your own reflexes; here you lose to a move that was available and that you did not consider.
The core idea worth knowing before you start is the double threat — a single move that creates two separate ways to complete a line, so blocking one leaves the other open. Almost every game at a reasonable level is decided by who builds one first. Watching for the opponent's is more valuable than building your own, because the opponent will build one whether or not you do.
The family also covers the two-player-on-one-keyboard case, which is the quickest way to make a browser game social. Paddle Duel takes two players on the same board with no setup, no accounts and no lobby, which is a genuinely different experience from playing against a program that never gets tired.
Which one to open
Pick by what you want out of the next ten minutes, not by the name.
| If you want | Open this |
|---|---|
| A thinking opponent | Four in a Row. It reads ahead, so it rewards planning and punishes the obvious move. |
| Two people, one keyboard | Paddle Duel. Immediate, no setup, and the only game here that needs a second person. |
| Solo board classics | Nova Minesweeper and Lumen Sudoku. The same deliberate pace, played against a position rather than a person. |
