- graphically: decision nodes connected/encircled by a dotted line
- player does not know where exactly where in the set he is
- i.e. player does not have full information on other players strategies
- Example Color Competition
- second player does not know what first player picked
- kind of simultaneous game
- at least for decision making it can be viewed as simultaneous
- therefore also a simultaneous game can be drawn as a graph
- Example Rock Paper Scissors
- both players do it at the same time, no information known before decision
