What?! You want us to guess the number which you are thinking just for merits? No offense but that's so insane dude. Do you really think this is a nice idea? Because for me, it seems non sense at all.
I understand that you are tired of discussing topics here in the forum over and over again that's why you wanted to add some fun by doing a game, but what I can't understand is why this game has no connections to bitcoin/cryptocurrency or being educational at least.
Besides your game has a very small chance of winning since there's a huge gap between 0-2000 so I bet no one can guess it. Anyway, I don't want to make an argument with you, I'm just sharing my opinion. So once again, no offense and good luck.
