Battle Cubes is a small duelling game from Bizak in the Marvel Spider-Man range. This starter set holds two cubes: Spider-Gwen in white and Green Goblin in purple, each with the character's face on one side.
The packaging sets the game out in three steps: select your secret attack, launch the battle cubes, and the loser gets captured. On the box the system is called the RPS auto-battle system - rock, paper, scissors.
According to the manufacturer, every two-pack also comes with 6 tokens to collect and swap. The cubes are small enough to go in a trouser pocket to school or to a friend's house.
Good fun for two children who want to challenge each other without a board or a table, and for anyone who already has other cubes from the Spider-Man range.
