Larry is a miner in charge of the machines at South Wheal Francis.
Every day, he has to set the machines all working by switching on all the levers.
Unfortunately, on this occasion, something has gone awry, and switching one of these levers on, causes two others to change.
This is causing Larry some bother, as he can't figure out how to get all the levers on at the same time, and he needs to get the machines running!
Play the cartridge to help Larry, and get all the levers in the right position, so the machines are running ready for a days work.
The cartidge can be found by clicking on Larry's banner at the top of the page.
