What should I do?
As long as you and the people you are playing with are in agreement as to what rules you are using, it doesn't matter what those rules actually are.
Many games that have existed for a long period of time and are taught by word of mouth tend to develop variations. But as long as all the players in one game know what rules are being applied, then the game should be fair for all players.
Some experimentation might be needed to find the ruleset that your group likes the most. But the beauty of games is that there is no wrong set of rules, as long as the rules are applied fairly.
Remember: the goal of playing a game is for everyone involved to have fun.
