In the co-operative card game Level 10 — which was first released as Okey Dokey — players work together to try to complete the challenge. In Okey Dokey, you are putting on a music festival with different performers and must play out all fifty cards in order to complete the performance.

In Level 10, you try to help Izzy play through all ten levels in each of five different video game worlds; each world is represented by a row of cards on the table. Players will play cards one by one to this 5x10 grid — 40 level cards and 10 reset cards — to (hopefully) complete the game. Players' hands are kept secret from one another and only slight suggestions can be made.

If a player cannot play a card on their turn, the players (and Izzy) lose.
