Even if you are playing relaxed I don't think you'll have a better result, you can just admit easily that playing dice is not that easy the most important is you enjoy the game with money that you can afford to lose and maybe next time you'll have better results, I notice you are using martingale the very old strategy to try to beat the house I also try that many times with average success.
Of course for the future I will play more relaxed and consistent, and I hold back my appetite to consider the amount of the bet and adjust it to the capital, maybe it was my worst day, I'm also sure playing more relaxed will understand the game situation
The most important thing is to be consistent and be able to control yourself, I used to be basically the same always greedy for bets but ended up making an instant loss, so I think now we have learned a lot about how to play gambling calmly and can also be disciplined, that's what I apply when playing.
To play dice I prefer small bets over big, dice are fast rolls if small bets I can bet long, but everyone is always different and at Stake.com the lucky dice are more.
