RNG and card shuffling
CoinPoker describes its card shuffling as Fisher–Yates, with a fresh shuffle for each hand. This guide explains that description and how to read fairness claims.
How the shuffle works
Fisher–Yates rearranges a deck through a sequence of swaps. The official explanation says the deck order is set before player actions begin.
Reading fairness claims
A shuffle algorithm describes how cards are ordered. It does not by itself establish the quality of the random input, certify an implementation or prove every part of game security.
Hand-history analysis
The official page suggests analysing hand histories and card distributions. Statistical checks need sufficient data and a sound method; a single result cannot establish whether a shuffle is fair.
