The most significant improvement of GT4 over previous offerings, for most, has likely been the evolution in the physics. Players must learn even more about the subtleties of real life racing in order to be able to 'drive' effectively in the game compared to previous racing games. However, traction and stability controls remain available to provide realistic driving aids for relative beginners, whilst they learn by completing various licence tests.

After the initial deal, the first of what may be several betting rounds begins. Between rounds, the players' hands develop in some way, often by being dealt additional cards or replacing cards previously dealt. During a round of betting, there will always be a current bet amount, which is the total amount of money bet in this round by the player who bet last in this round.
