Each Player needs to buy at least 1 Ticket to participate in the game. When the game begins, numbers are drawn in a random order, and the board on the right shows all the numbers in the order that they have been drawn.
The player needs to cross or dab all the numbers that are drawn in the ticket, as called by the dealer. If you join a game late, you can still cross the numbers that have been called out previously. The player who crosses out the numbers in a winning pattern, will need to click on the "Claim" button. If more than one claimant, whoever is the fastest would be declared the Winner for that pattern.
If your claim for a pattern is wrong, it will be treated as a Bogie and you would not be able to continue with the same ticket.
The game ends when all the 90 numbers are drawn, or when a winner has been declared for all the patterns of the game, whichever comes first.
