A keno ‘split ticket’ is simply a way of making more than one straight ticket bet on the same ticket.
Each separate bet or ‘game’ is denoted by circling or drawing a line to separate off a group of numbers.
On a split ticket each game must have its own unique numbers. Any given number can only be included in one game (group of numbers). There can be no overlap.
The only advantage to a split ticket is the convenience of playing two or more games on the same piece of paper. It makes no difference to the payout. Each bet is viewed as entirely separate, and you pay for each of them.
