AV Jiu Ji Ma Jiang II (AV究極麻將2), also known as AV Kyuukyoku Mahjong 2 is an adult versus Mahjong game developed by Hummer Team and released by Ge De Industry Co. around 1995. It is a backport of Dial Q wo Mawase (ダイヤルQをまわせ!), an unlicensed Sega Mega Drive title.
Sark is unlike any word game you have played: a challenging addictive intergalactic brain battle you can play by yourself, with friends, and with players around the world!
25 letter cards are dealt one at a time from a 54-card deck. A player places each letter in their Sark Square (a 5x5 matrix) to form 3, 4, and 5-letter words across and down. Games last on average 5-10 minutes. A perfect score is 70 but there is no record of anyone scoring more than 60, and 50 is rare!
