Whereas most faucets only allow you to claim once per hour or once per day, this allow you to claim as often or as little as you like*
The faucet will gradually fill up - quite quickly initially but it will slow down over time - until you make a claim. So the longer you leave it the more you will be able to claim.
You may prefer to claim a smaller amount every 5 minutes, or visit once per day and claim the large amount that has built up while you were away!
