XTRA is a feature for the Pick 6 and Jersey Cash 5 games. It works as a multiplier - it will multiply any non-jackpot winnings by the XTRA number.
When playing Pick 6, the XTRA multiplier is included and automatically added to each ticket at purchase. A random XTRA number of either 1x, 2x, 3x, 4x, 5x or even 10x is displayed on the ticket along with your chosen numbers and indicates the multiplier value.
For Jersey Cash 5, the XTRA multiplier is an optional add-on feature. XTRA has a fixed price of $1 per play and can be added to the ticket on the checkout page. When the winnings numbers are drawn, an additional ball is drawn to determine the XTRA multiplier for all tickets included in the draw.
