In 'High Rollers' the contestant has to make their way over cylinders that are suspended over water, each slightly higher or lower than the previous one.
The rollers aren't fixed still so will spin around when stepped on. The contestant needs to move quickly, and have good balance, so that they're not rolled off. If they fall into the water, they lose. By making it onto the platform at the end of the rollers the contestant wins the game
To begin with, there were only three rollers that needed to be crossed. This was increased to five, and then to seven.
