Deal

One deck of 52 cards is used, with cards ranking in descending order as follows: 2 A K Q J 10 9 8 7 6 5 4 3. Twos, Tens and Aces have special privileges. Each player is initially dealt five cards (2–2–1). The rest of the cards form a face-down stock.

Play

In turn each player, with or without drawing the top card from the stock, places one or more cards of the same rank from his or her hand onto a pile next to the stock according to the following rules:

• If the pile is empty, any card (or set of cards) may be played to start it.
• If the pile is not empty, the new cards must be of at least the same rank than the previous cards in the pile.
• Twos can be played on any card except an ace or ten. Only a two can be played on top of another two.
• Nothing can be played on a ten except another ten; likewise only an ace may be played on an ace.
• If the top card is lower than a seven, no court cards may be played.
• Aces can only be played onto a court card or another ace.

A player who cannot or does not want to play, must take the entire pile in hand and the turn rotates left.

A player who, after playing, has fewer than five cards in hand, must draw cards from the top of the stock to bring the hand up to five cards. Obviously this is only possible if the stock is not exhausted.

A player who gets rid of all his or her cards after the stock has been exhausted is out and does not participate in the game any more. The first player to go out is the winner. The loser is the player who has cards left when everyone else has gone out. In some circles the loser is called paskahousu.

Valepaska

In Valepaska, also called Valepaskahousu and Kusetuspaskahousu and often considered standard Paskahousu in English literature, the cards are played face down, and players announce the cards that they play (for example "one jack" or "three eights"). Players are allowed to lie, and plays may be challenged by any other player. In a challenge, the played cards are exposed: if the play was honest, the challenger must pick the pile up (and the challenged player starts the new pile); if the play was deceitful, the challenged player takes the pile (and play passes to the next player). Only the immediately preceding play may be challenged.

According to Finnish website Korttipelit (card games), there are no standard rules for which player continues play following a challenge. The website recommends that an exposed liar never start the new pile.^[2]

Pöytäpaska

Pöytäpaska (Table Paskahousu) also known as Espanjalainen paskahousu (Spanish Paskahousu) In addition to their regular hands, each of the 2–3 players is dealt four face-down cards and four face-up cards. These cards are played after the stock and the cards in the player's hand have been exhausted. The face-up cards are played first. The player can then attempt to play the face-down cards without looking at their rank. If the play is not in accordance with the rules, the player must pick up the entire pile into their hand. These cards in hand must be played before the player can attempt to play another face-down card.^[1]

To avoid deadlocks and lengthy games, some rules may be relaxed after the stock is depleted, such as:

• rules restricting the play of court cards
• rule that the ace does not clear the play pile
• rule restricting the play of the ten
• rule restricting the play of other cards on a two

Ruotsalainen paskahousu

In Ruotsalainen paskahousu (Swedish Paskahousu) all the cards are dealt, and there is no stock. The game proceeds like the ordinary Paskahousu.^[1]

Miscellaneous rule variations

These rules can be used with the basic game or with any of the variants mentioned above.
