there are many questions in this.
you can set up a discount of $5 and $10 and $15 etc for however many games they opt out of.
custom reports only show up when using the Square dashboard online so you could view that in a web browser instead of the app.
I'm not sure you can even use Square to sell bingo cards as it may be considered gambling which is prohibited under the terms of service.
also, it is against the terms of service to offer cash advances. so you can't just take a credit card for $50 and give back $50 in cash (also because you'll lose money on the transaction)
