Sometimes we can have fewer people playing the game (say a group of 5), increasing the probability of a Bingo so it would be good to reduce the numbers so that the games are a bit faster.

Really great website, simple to use. One thing I would suggest would be to only click the call / stop button once as opposed to clicking it and having to stop it for it to land on a number

For the ticket page, can you save the state of the ticket in case you accidentally close the window or refresh so that it doesn't lose your ticket or lose which numbers you've dabbed

I'd suggest having the bingo lingo appear on screen when the number appears so you don't have to look for it in the list
