Is the number 777 good or bad?
Number 7 means the planet of shadow - Ketu. According to the Vedic tradition, Ketu 7 is classified as bad planet (papa graha), which holds and gives to population their bad karma.
Why the number 7 means bad karma?
There are several forms of karma, one of which is the karma associated with previous incarnations, with previous lives. We live in an era called Kali Yuga. This is the last of four Yugas. And we not only live in Kali Yuga, but we live at the very end of Kali Yuga, in the sandhi phase. Sign of Kali Yuga Sandhi is that in this era is realized mostly negative karma - human life is relatively short, and there are a lot of events and the trend is generally negative.
As we have already seen, number 7 relates to the karma of previous lifes - and in this life we receive results for the actions or the unhappiness we did before.
7 + 7 + 7 = 21 = 2 + 1 = 3.

Number 777 and casino
Often, these numbers 777 are used as casual numbers in the casino business.
Here we will give a clear answer whether this number is successful and happy that allows you to get or to "win" something. The answer is unequivocal - no, everyone is not successful and happy, because everyone does not have the same karma.
An example with a casino can be well described with the situation in the context of several lives. For example, in one of your previous lives you were a successful businessman, but one of your clients fooled you and did not pay for the work done. Due to this fact, for example, you died and did not receive money. In this life the one who did not pay will be unsuccessful gambler who will lose money in the casino, but you are in relation to the historically established debt and you will be "winner" because you will "win" money. If we look at the context of one single life, then it will be a great catastrophe, misfortune for one, for the other it will be great happiness. But if we would have the opportunity to remember all of our previous incarnations, then we would understand that through gambling hall we are getting back only what someone have been owed in advance or on the contrary - we reclaim the debts from those who have previously cheated us etc.
In this context, it can be said that the number 777 will be a fair number, which will be distributing to each for merit, because 3 is a Guru - in a Vedic tradition - teacher who make everyone to follow the dharma, and makes sure that everything is going right, with that - 3 through three 7 will distribute the karma to all by merit.
