That machine is a lotto machine. I have seen it in my location in any time or is it use for another thing too. I have not used it to lay game so I am not too familiar with it but I ga e followed people to the Lotto centers so IA he seen it. People use numbers to play Lotto game. And according to players when you win, it hit big amount. And that is the jackpot.
The terminal almost looks like a bigger point of sale(P.O.S) machine, but instead of printing receipts for cash transfer or withdraw or recharges, it is used to stake, process games and print receipts for the players to hold onto and present Incase their numbers drop as a win.
I have seen this machine several times and understand that it operates on a fixed odds lottery system mode, wherein numbers between 1 to 90 is picked and one needs at least two of their numbers to drop in the official draw to win.
