太陽と月の王国 (Taiyo to Tsuki no Oukoku)

太陽と月の王国 (Taiyo to Tsuki no Oukoku), roughly translated as Kingdom of the Sun and the Moon, is a climbing game where there will be one loser among the players. The game uses a pyramid deck of cards (one 1, two 2s,..., ten 10s) and a player's "hand" of cards is split between cards that are dealt to a traditional hand, and cards that form a pyramid in front of each player. This pyramid is face down, except for the front row, and players can choose to play cards from their hand, their pyramid, or a combination. Players can play the same rank as a previous player, and if 4 of the same rank have been played, the round ends immediately, with the current player winning that round and the ranks of cards reversing. Rounds continue until only 1 player has cards left in hand; that player loses 1 life. Once 1 player has lost both of their lives, the game ends, and they lose.
