This is Tetris Ultimate for the Nintendo 3DS. It's region-coded for 2DS and 3DS systems sold in North America. Its single player modes include marathon (clear fifteen levels), sprint (clear forty lines), endless, and ultra. The player can also see game replays. The game was delisted from all stores in 2019. The online modes no longer function. However, local play options should work for people who have a 3DS Street Pass fan group in their neighborhood. I bought Tetris Ultimate in used condition from a Gamestop store. The plastic case, cartridge, and Club Nintendo flier are all in Very Good shape. I will ship this game by USPS mail in a padded envelope. Domestic shipping is free.
