King of Tokyo is a dice rolling, press-your-luck, yahtzee-style, Kaiju (Giant city destroying monsters) game for 2-6 players, and is a quick play at around 30 minutes.
In King of Tokyo, players take on the role of giant monsters, aliens, robots and so on—all of whom are destroying the city of Tokyo while also beating up on each other in order to become the one and only King of Tokyo.
At the beginning of your turn, you roll six dice, on each dice there are six symbols: the numbers 1, 2, and 3 (Victory Points), A Lightning Bolt (Energy), Heart (Health), and a Clawed Hand (Attack). After your throw choose whether to keep or discard each die, re-roll the discarded dice and choose which dice to keep or discard again, then re-roll one more time to determine victory points, energy gained, health restored, or the amount of damage you do to other players.
The bravest and strongest monster will occupy Tokyo, and earn extra victory points, but while in the city that player can’t heal and must face all the other monsters alone!
Special cards can be purchased with energy. These cards may have a permanent or temporary effect such as the growing of a second head which grants you an additional die, body armor, nova death ray, and more.
In order to win the game, one must either destroy Tokyo by accumulating 20 victory points, or be the last monster standing once the fighting has ended.
The thing I love about this game is that it can be very fast and furious in the best way possible. Sure you COULD wait until you’ve earned 20 victory points but after somebody’s monster starts pushing around other monsters a monster sized brawl starts and the game quickly turns into a violent game of king of the hill Kaiju style. This makes the game pretty quick allowing you to set-up for another round and get through a few plays in the time it takes for many other games.
The game is also very simple and light-hearted. You won’t have to worry about intense strategy or a lot of rules, you can nearly turn you mind off and roll dice. If kids can understand yahtzee they will have a basic understanding of King of Tokyo which is recommended for ages 8 and up.

Sex: None
Swearing: None
Drinking or Drugs: None
Horror/Occult: Monsters, big Godzilla/King Kong-esque monsters.
