Seriously, you really need a front-end developer in your team.
Or at least pick a less-stressful color, gamblers will stare at their monitor for hours and the visuals are pretty important in that case.
My question is:
If ever a gambler questions the coinflip's match making for being suspicious about his previous opponents, claiming that those must be bots, what would be your answer?
And how can you explain to us that it is a "real" player, not a bot? Because it's technically possible.
As I said about the design that I would call it a placeholder for now while I'm creating the main functions of it. I'm always open for suggestions how/what colors to use so it would be a lot better

. To just add there's no team it's more like One Man Army.
About the bot, as there is no "bot system" in place so I'm not really sure what to answer and even if there is a "bot" I'm not sure what would be the problem as the odds wouldn't change.
