I would like to know because I don't seem to get it... How come I sometimes loose when for example both cards have 7 power and one 10 pillz and the other 7
I know highest attack does not always win you the battle but still, such a difference?

Don't play 'Random' rooms.

I'm playing elo, it's posted in elo o_o

Room option: 'No random, the highest attack always wins.'

In randoms the only guaranteed win is to double the end total. While the more Pillz you throw in will increase your chance of winning, it is still an increased chance. If randoms are throwing you, just do what Endymio_LW suggested, play non-randoms.

Someone else who doesn't understand this.

1. this
as a demonstrative pronoun, this denotes something that is present or near in place or time, or something just mentioned, or that is just about to be mentioned

2. this
as an adjective, this has the same demonstrative force as the pronoun, but is followed by a noun; as, this book; this way to town

Glad to be of help razvan.

When two cards have equal attack, the card with lower stars wins. If they are equal in star count, the attacking card wins.

Oh well, thanks for that, I need help at grammar

Next time it happens, try taking a screenshot, it would be easier to see what is happening, there could be things like banger/Ulu Watu bonus that you forgot about when you say 7 power, or a Leader (unlikely because you are playing ELO), or when the 10 pills is 7 pills + fury vs 7 pills, in which case they would be same attack (7 power x (7 pills + 1 starting pill) = 56 attack for each), fury only matters if you win a round.
