What's the problem? Though it's definitely in the 'unlucky' side, losing 13 times in a row is definitely a possibility. It's not like the possibility of you winning the gamble goes up after every loss.
Also, with freebitco.in, the possibility of you winning a x2 multiplier is 47.50% not 50%.
not quite, i have had more rounds today, i lost 10 times on another round , but i won 1 times and recovered my lost satoshi, say wathever u say this is not a provably fair game... also a friend played some months ago and he lost 17 times in a round, for y'all if you dont want to risk your satoshi, dont bet on this website.
In most online casinos, including crypto and non crypto casinos, games are provably fair. The mistake that players always make is that they ignore the fact that house edge has power there and they can't go against mathematics rules when you play with numbers.
Always win on long term is on casinos's side, games have house edge because to keep casinos running their business and getting profit from it. Without house edge, casinos would go bankrupt.
You also miss one fact, the provably fair games aren't tracking your previous bets and think, oh this man has done bet 15 times and now it's time to win. New bet = new story written on new paper where your old data doesn't even exist.
And if anyone wants to play dice, logically they should look for other websites where dice is their main target and offer dozens of promotions around it along with 1% house edge.
