7 Ate 9
7 Ate 9 is a quick-playing card game in everyone wants to rid themselves of cards as quickly as possible — but you can't play just any card you want! Each card features a large numeral (1-10) as well as a smaller numeral in the corner (±1, ±2, or ±3).
To play, place one card face down in the center of the table, deal the remaining cards out evenly among all the players, then reveal the central card. Players race to add the next card to the central pile. A card with a large 5 and a ±2 in its corner, for example, could be covered by either a 3 or a 7 (since 5-2=3 and 5+2=7). The first player to get rid of all their cards wins.
