Making your own lottery application

The addition of a lottery Application to our local club and the restrictions working with lotto providers got me thinking. How can I generate lotto numbers and more importantly make a plugin to allow members to play it online while removing the 6% to 10% the provider charges for the service.

I went to ChatGPT and asked how to generate lotto number as a quick pick but also as a user input.

I eventually settled on this version of the code which allows registered club resellers to sell tickets on iphone or android device , accept cash or a till receipt. This option allows the committee to sell tickets at events with multiple sellers.

The full code is listed below.

Of course there are many paid plugins which already offer a solution , once I have reviewed this further we may revisit this…
