Just don't play random mode, it will make you not hate the game. Seriously, it is that simple: Random is random. You have more chances of winning with more attack, but that doesn't mean you will be winning.

It is completely random . Although there was a post some months ago that a few people were actually saying that the better your computer is the most battles you win

So you want to understand random mode. First piece of advise, don't play it.

Random mode works on a percentage basis. If you have 100 attack and your opp has 50 you will win because your attack is double your opps attack.

If you have 100 and your opp 60 it is like a tug of war.

You have 10 players and your opp 6.

( - - - - - - - - - -// - - - - - -)

The odds are in your favor but your opp has a chance of winning.

Who's ever attack is higher but doesn't double has the higher chance of winning but might not.

I don't think level has anything to with anything. It goes like this, lets say 40 vs 24. You add them together (64), the 40 has 40/64 chance of winning and your opponent 24 has 24/64. So you have about 62% chance of winning and your opponent 38%. Random is underrated, it all evens out, the winning because of random and losing because of it.
