imagine if there are no tip limits, then one could simply claim faucet then tip another account, claim it again - rinse and repeat then withdraw
it would have been too easy to abuse for players who do not play and just come to claim freebies
you can withdraw your coins , then redeposit and you can tip as much as you like , you can convert bitcoins to ltc or doge to make the process go faster
and yes , the level system allows you to have 55 claims per day with 108 satoshi per diamond , up to 13 diamonds per game = 1404 satoshi max
in reality , I only managed to open all of the diamonds once , usually it is 3-10 diamonds for me , but a 500 satoshi faucet (on average ) is among the best ones at the moment
