I personally really like fast games, where you bet and then see how much has time to run. And most importantly - to have time to collect your winnings. Children usually help me - they run and feel what is happening, they tell me when it is better to take pictures. I don’t know what works more here, childish spontaneity or childish intuition, but in any case it will turn out very nicely. So you can do it with any such game
