My childhood UNO is a lie

Most of us have played the popular card game UNO before some time or other. And we are probably very familiar with the basic rules - you can only throw a card that matches the colour or number/power type of the top card on the discard pile. The 'taiji' rule is something we should all know too - if someone tosses a Draw Two, you can quickly put another Draw Two and 'taiji' a resultant Draw Four to the next player. And so on and so forth.

Today was probably the first time I read the rules while playing it during reservist *cough*, and I realised my childhood UNO was all a lie. For one thing, the 'taiji' rule doesn't exist. If you put a Draw Two or Draw Four, the next player must draw it. And to add on, Draw Four comes with a condition - you can only put it when you have no other card that matches the colour of the card previously played. The fun part is that you can play it illegally, but just like many other things in this world, just don't get caught. If you are hit by a Draw Four card, you can challenge the player to show his hand to you. If he is guilty, he has to draw the four cards instead. If not, you would need to draw six cards.

Oh, and the rule that you can't end the game on a power card? That doesn't exist too.
