The cards are dealt randomly on each street (Flop, Turn, River) and are not known on the pre-flop. The Random Number Generator (RNG) used to deal cards on our website is licensed by Gaming Labs, an American RNG testing organization.
In addition, in June 2018, the RNG was re-certified by the Australian company [iTech Labs] (http://www.itechlabs.com.au)
