The easiest game was Exorcist, nearly everyone recognized it, followed by Treasure Island, Bongo, Hustler, Mr. Puniverse and Tutti Frutti.

The toughest one was Cave Fighter by Bubble Bus. (Their other game - Hustler - is obviously more popular!) Locomotion, Xcellor8 and Dizaster Blaster were also apparently hard to figure out.

Almost everyone submitted only correct guesses, here are the mistakes:
Leaper -> Major Blink
Cave Fighter -> Varmit, Summer Events
Disaster Blaster -> Megabolts
Hollywood Poker -> Terra Cognita
Treasure Island -> Icicle Works
