At the Very End of the Boundary Line

Description from the publisher: Beyond the horizon lies the sky, and beyond the sky lies the universe. This trick-taking game aims to reach the very end of that very horizon. Players take turns playing cards, and the person who played the strongest card wins the card that was played. When playing cards, there are restrictions: ・Play land/sea first ・Land and sea cannot be played at the same time ・The numbers must always be space > sky > (land/sea). When someone can no longer play a card, the game ends and the score is calculated. ・Land/sea: 2 points for the most cards ・Sky: 3 points for 1 card (maximum number of land/sea cards scored) ・Space: 5 points for 1 card (maximum number of sky cards scored) ・Sky/space that could not score: -3/-5 points This is repeated three times, and the person with the highest total score is the winner.
