In Galaxy Wrestling Federation, you need to overcome opponents so that you can win championship belts and win the entire event, but you have only a small hand of moves that you can make, so manage them well!
Each player receives a hand of ten wrestling cards and one victory card; each wrestling card has a strength value on it as well as an opposing value that it overcomes. On a player's turn, they choose an opponent who doesn't have the most cards on the table in front of them and challenges them to a bout of either strength or speed. Each player chooses a card in hand, then reveals them simultaneously. If your card overcomes the value that your opponent played, then you win the bout automatically — unless you each overcame the other's number, in which case the bout is a tie.
If no one overcame the other, then you compare the values of the cards themselves. In a strength bout, whoever played the higher value wins; in a speed bout, the lower value wins; in a tie, the bout is a tie. If a single player played their victory card, then they automatically win — unless the other player did the same, in which case you tie.
The winner of the bout returns their victorious card to hand (except for the victory card, which is a one-shot effect), while the loser places their card face up on the table in front of them. The winner receives a championship belt token, then the next player in clockwise order chooses an opponent.
In a bout, before both players reveal their cards, they count to three, and while they're doing this, a third player can interrupt by playing one card against one of the cards in the bout. If the interrupting player overcomes that player's card, they win the bout and receive a championship belt token, returning that card to hand. If they don't overcome the card, they place their card face up on the table, then the bout resumes.
When one player has three pairs of card values face up in front of themselves (e.g., 1/1/2/2/3/3), then the game ends. This player loses, and whoever has the most championship belt tokens wins!
