From the $5 free bet, I managed to win $50, I use $30 for other crazy multi bets and use the other $20 to play slots but lose it at all.
Here is my some of crazy multi bets for the world cup matches:

Win of them will be nice, lose them all is also fine because they came from free bet promo only.
By the way, previously I wanted to try the in house games such as dice, plinko, but when I click it, it redirects me to the slot games page.
Is there something wrong or the in house games are not yet ready to play?
