Sorry to hear that, I think it might be better to stop playing for a while and sort out your finances if you can... as continuing to gamble will just drop you into deeper shit.. if you are already in deep shit go to a citizens advice centre if you have one nearby and get some help to sort out debts... it won't wave a magic wand, but it's a start...
Maybe you need to change your style of play. Practise a new strategy in fun mode for a bit without risking anymore of your own money? Or maybe just quit altogether and do something completely different, and if you come back just deposit a small amount to test the water...
I think the slots are high variance. I'm not really a big slots player, I just dabble in them every now and again, preferring table games.
I've only been a member of 3Dice for a few days but my experiences of the games so far have been good.
For blackjack what strategy are you using?
All blackjacks online are streaky I have noticed. Sometimes they seriously suck, and you can't get a win in edgeways, cause the dealer seems to get good hands pretty much constantly and you're always getting dealt crappy low hands like 15/16. When you're in this situation the only thing you can do is lose. It is frustrating and painful to be sure.
Don't use martingales, you can't beat any online blackjack with those, because it is quite common to lose more than 7 times in a row every session, and using martingales will either cause you to hit table limits or lose your entire bankroll. If you use a martingale only use a 4 or 5 step one and then bail out if you don't win...
It is better to use a strategy that sticks with the minimum bet when you're on the losing streak, and then up the bets on the winning streak, this doesn't always work, like today it went pear shaped for me... but I find it works better than the martingale. I have lost using this strategy also but at least the losses aren't so big.
Blackjack is a fickle game. I have noticed sometimes you can lose 11 games in a row, win 2 and then lose another 5 in a row, win 3 then lose 8.... which makes it impossible to win with any strategy. Unless you have ESP and bet extremely high when you know you're going to win. Sometimes with blackjack nothing works and its best to stop altogether and leave well alone or you'll end up losing everything.
If you find any strategy isn't working on any game, it is best to set yourself a losing limit, for me it is roughly $25 and I also set a winning target for me to make +$25... whichever I hit first I stop. You probably like to place larger bets than me, so I don't know what your target is... but if you hit either the negative or positive target stop... this is hard, as often it can spoil the enjoyment of playing, but is safer.
I am a low roller at the moment, as I am out of work and due to chronic illness can't afford to go crazy with my bets... but even as a low roller when I lose it hurts as I only have one stack to play with which I won't be replenishing unless I find a treasure chest...
All I have left at the moment is what is in my neteller account and some savings (which aren't for gambling, they are for keeping us alive whilst I pray for some more work.) Once all the funds have been bled dry from my neteller account, that's me done. No more gambling... I will live off my savings from that moment on and if I don't find work during that time, once my savings are gone, I will have to go on the street and try busking again...
incapacity benefit isn't enough to support a family, due to stupidly high food prices and energy bills... at the moment playing blackjack is keeping me floating... but once my neteller account is empty, which I guess will happen sooner or later then I will be dropped in shit creek without a paddle...
If gambling is bleeding you dry is best to stop, or only play with a set amount you can afford each month. This is also stuff everyone knows, is just hard to put it into practise, but we all need to, else it is easy to slip into financial ruin.
Maybe just play in fun mode to practise new strategies or play the free tournaments... so you can play the games but without risking anymore money... and practise out new techniques... till you feel confident enough to try again... but don't risk large amounts of money if you do, it isn't worth it...
My brother told me about a friend of his who got drunk and played blackjack online one evening, he started placing stupidly high bets and ended up losing 7000 in one night. He is an accountant, you would think he would know better
