The game
Knock knock!
Every round, 1 new room goes under every door. Everyone picks a door in secret, puts that door card face down, and at “Knock knock!” everyone turns their card over at the same time. A game lasts about 10 minutes.
Room cards
Alone at a door? The rooms are yours
Alone at a door? You take ALL the rooms under it. Two or more at one door? You bump: nobody gets anything, and the rooms stay put and pile up. The card you just played rests face up for one round. When the rooms run out, the player with the most stars wins.

Questions & answers
How do I get the files?
Enter your email in the box above and tap the button – the PDF links (A4) appear right away on this page. You can switch the language of the files there too. US Letter size or everything in one ZIP: use the small link under the files (free checkout).
Do I need special paper or a printer?
Any home printer works. For everything you cut out (cards, boards, pawns, dice) we recommend thick card stock (250–300 gsm); print the rules and play sheets on plain paper. If the game has cards, the ZIP includes a short guide to double-sided printing.

No. The free edition costs nothing, and we ask for neither your address nor a card. If you like it, the full edition is a paid download.
