Fourfold

Fourfold is a game about seeing one move further than the person across the table. You drop a token into one of seven columns, it falls to the lowest open slot, and the first player to line up four — across, down or diagonally — takes it. That's the whole rulebook, and it takes about ten seconds to learn.

What takes longer is learning to spot the trap two moves before it closes. The computer opponents are built as a ladder rather than a dial: Easy makes real mistakes and is genuinely beatable, Medium blocks your threats and plans a few moves ahead, Hard sees the traps coming, and Perfect searches deep enough that beating it earns you a badge. Every game is tracked in My History — your record against each level, your best winning streak, and the last games you played.

Two ways to play

• Solo — climb the four-rung ladder, from Easy up to Perfect, with a running session score against whichever opponent you're facing.
• With a friend — open a private room, share the code or the link, and play head to head in the browser. Rematch as many times as you like; the series score rides along at the top of the board.
