Sumo Card Game
Rules Version 1.1
1.1 Updates: Optional rules for Jokers, Challenge "tie" clarification, "out of ring" clarification

The Sumo Card Game is a two player game that uses a standard 52 card deck. Jokers may optionally be added to make it a 54 card deck, but are not required. The goal is to gain advantage each round and push your opponent out of the ring.

SETUP

1. Shuffle the deck, and deal out two seven card rows of facedown cards between the players. These represent the ring, and will be referred to as ring cards. Each pair of cards make up a column, so there are two rows, and seven columns. Each row is assigned to each player, as are the sides of the ring. If playing across from each other, each player should take the side to their right.
   
   
2. Deal out two cards, each face down and on opposite sides of the ring at the center columns. These represent the sumo wrestlers themselves, and will be referred to as sumo cards. The sumo cards are associated with the player who has same row.
   
   
3. Deal out three card hands to each player. These are attack cards. The remaining cards make up the deck. At the end of each round, each player will discard attack cards they have used that round into the discard pile, and draw from the deck until they have three attack cards again.

ROUNDS

(Explained in detail further down)

1. Players place attack cards facedown.
   
2. Flip over attack cards, determine winner. If a tie, skip to step 7.
   
3. If the ring cards in the current column are facedown, the pushed player may challenge using ring cards.
   
4. If the sumo cards are facedown, the pushed player may challenge using the sumo cards.
   
5. If pushing, move the sumo cards an appropriate number of columns in the direction of the pusher's side.
   
6. If the sumo cards have moved outside of the ring, the player who did the pushing this round wins. Note that the last column on either side is still inside the ring; the sumo cards must be moved beyond one of those last columns on either side for the game to end.
   
7. Place attack cards used this round in discard pile.
   
8. Players draw until each have three attack cards. If the deck runs out, shuffle the discard pile to remake the deck.

PLAYING CARDS

Players attempt to "push" each other using the attack cards in their hands. Each player selects an attack card from their hand, and places them face down. Once both players are ready, the cards are flipped over. The player with the higher number pushes the other towards the pushing player's side of the ring. In the event of a tie, the round ends with nobody being pushed. Face cards push harder than Number cards, and Aces push hardest of all.

• 6-10, Face Cards, and Aces - Always just play one card with this range. Jacks are essentially 11, Queens 12, Kings 13, and Aces 14.
  
  
• 4-5 - You can play 4 and 5 cards like the 6-10 Number cards, but you can also play pairs and get a higher number. You may play two 4 cards as though they were a single 8 card, and you may play two 5s as though they were a single 10 card. Two 4 or 5 cards are no better or worse than single 8 or 10 cards, respectively.
  
  
• 3 - You can play one, two, or even three 3 cards in a single round for values of 3, 6, and 9, respectively. Note that using three 3 cards to make 9 is the only way to play 3 cards, so your opponent will know. On the other hand, you will also get to draw three cards at the end of the round.
  
  
• 2 - 2 cards are wild. When you reveal a 2 as your attack card, you draw a card from the top of the deck and use that value instead. If that card drawn is a 2, you draw again until you get something other than a 2. If both players play a 2, draw cards in whatever order you've decided upon for drawing at the end of rounds, or just randomly decide who draws first.
  
  
• JOKERS - Jokers, if included, count as 2s, or can be played as 3s, 4s, or 5s in combination with 3s, 4s, or 5s. If you play the Joker on its own, it's treated as though it's a 2. Any Jokers that are ring or sumo cards are treated like 2s. If played as an attack card, however, you can play them as part of a combo with 3s, 4s and 5s.
  
  Every possible way to play a Joker:
  
  • Joker on its own as a 2. The Joker is always a 2 if it's a ring or sumo card, or if it's drawn as the result of a 2 or another Joker.
  • Joker and a 3 to make 6.
  • Joker and two 3s to make 9.
  • Two Jokers and a 3 to make 9.
  • Joker and a 4 to make 8.
  • Joker and a 5 to make 10.

If the players care about who places their card(s) face down first, have the player whose side the sumo cards are closest to, AKA the player who is currently winning, place their card(s) facedown first. If in the center column, such as on the first turn, randomly decide who does so first. This game does not require this level of strictness, but some players may prefer it.

PUSHING

When pushing an opponent, the sumo cards are moved towards your side of the ring. If your opponent pushes you, the sumo cards move towards their side of the ring. If the sumo cards are pushed outside of the ring, then the player who last pushed the other player wins.

Classes and Distance

There are three classes of cards: Number, Face, and Ace. Each class is progressively better at pushing the lower classes.

• Number cards can only push lower Numbers one column. Combos made using 3s, 4s or 5s count as the sum of those cards.
  
  
• Face cards push all Number cards two columns. Stronger Face cards push weaker Face cards one column. Kings push Queens and Jacks, and Queens push Jacks. Face cards cannot push Aces.
  
  
• Ace cards push all Number cards three columns, and all Face cards two columns. The only thing Aces cannot beat are other Aces, which results in a tie.

Example: Tedd plays a Jack, Elliot plays two 5s to get a 10. Jacks are Face cards and 10 is a Number, and Face cards always push Number cards two columns. Elliot is pushed, and the sumo cards move two columns towards Tedd's end of the ring. If this takes the sumo cards past the last card on Tedd's end, Tedd wins.

CHALLENGING PUSHES

If still facedown, it is possible to prevent pushes by using ring cards and sumo cards, though sumo cards can only be used if the ring cards in the current column have already been used. Note that only the pushed player can challenge the results, and that it is entirely optional unless not doing so would cause them to lose once pushed.

As has been said, the sumo cards are positioned with a column of cards on the row, and start in the center. Those cards aren't just to show where the sumo cards are. If the ring cards in a column the sumo cards are currently in are facedown, they can be flipped over. 2s are treated just as they would be if these were attack cards, and the cards drawn as the result of 2s are always discarded as such. Ring cards and sumo cards are never discarded.

The player whose row has a higher value wins the challenge. If the pushed player wins, the push is canceled, and the sumo cards stay where they are for this round. If the player doing the pushing wins, the challenge affects nothing, and the push still happens using the values determined by the original attack cards. In the event of a tie, the push is canceled.

If the pushed player loses the challenge using ring cards, or the ring cards are already face up, they can still challenge the push using the sumo cards if they are still face down. This works exactly as challenging does with ring cards, except there can only be one sumo card challenge per game. It is, in essence, a last ditch effort to not get pushed out of the ring.

Once again, note that only the pushed player may make challenges. The pushing player cannot issue a sumo card challenge to try to still push after losing a ring card challenge.

Example: Tedd's attack card is an Ace, and Elliot's attack card is a 9. If Elliot doesn't challenge, his sumo card will be pushed out of the ring, and he will lose. The ring cards in the current column are facedown, and he challenges. Tedd's ring card is a King, and Elliot's ring card is a 3. Elliot has failed to stop the push with this challenge.


Elliot's not beat yet, however, as their sumo cards are still facedown. Elliot's sumo card turns out to be an Ace, and Tedd's is a 2. 2s are wild, so Tedd draws from the deck, but gets a 4. This second challenge succeeds, and Elliot is not pushed . The sumo cards are now face up and cannot be used for challenging again, and do not move this round.


Note that even though Elliot got an Ace versus a 4 during that final challenge, Tedd is not pushed. Challenges prevent, and do not cause, pushing for the current round.

Also note that Elliot would have lost had he not challenged the push, so he had no choice but to do so. If the pushing had been such that it would not have cost Elliot the game, he would not have had to challenge it. It can be good to save the ring and sumo cards when only facing a one or two column push, depending on how close you are to either side of the ring.

END OF ROUND

At the end of the round, assuming nobody has won, the attack cards used this round are placed in the discard pile, and each player draws from the deck until they each have three attack cards. If the players care about the order the players draw cards in, determine that order before the game.

If the deck runs out of cards, set the discard pile facedown and shuffle it. It then becomes the new deck that cards will be drawn from.

THE END

And that's the game. Play cards, and push your opponents out of the ring. Enjoy!
