Make the game more streamlined, for example:

• the player need to add a coin in the pot (rolling dice is inactive and he can only add one coin)
• the player can roll his dice (button is active)
• the player need to add another coin in the pot (selecting dices is not possible, and he can only add one coin)
• the player can select the dice and reroll

So the player cannot add more than 1 coin and can only do that if necessary (for begin to play or for continue after the first roll)

Done!
