On the left you can see chores. The one second chore (it actually take one second) gives you one dollar, but you have to wait 1 second. Sam with the $5 and $10 chores. When you have $10, you may press the $1 per second chore, where you get $1 per second, for a price of $10. This is more efficient if you are playing for more than 10 more seconds, and you do not have to click anymore. But don’t click either of the things on right before having enough money, because then it is game over.
