Play Investour

An Investour match: four players around a board of city properties, with two dice in the middle

Dutch

A cunning memory card game you play online with friends. Everyone gets four face-down cards they can't look at. Swap your way to the lowest hand, remember what you've seen, and call Dutch before anyone else.

  • No sign-up. Create a table, share the code, and your friends join straight from their browser.
  • Special cards. Jacks swap any two cards on the table, Queens let you peek, Aces hand a rival an extra card, and red Kings are worth nothing.
  • Match out of turn. Hold the same rank as the card just discarded? Throw it on top, but guess wrong and you take a penalty card.

Play Dutch

A Dutch table for three players: each has four face-down cards, with the deck and the discard pile in the middle
