Attack matching algorithm

I am a level 49 with a town hall level 6. I’m near the top end of a TH6 which means I’m 16 hours from completing the upgrade to a Th7 and everything else is maxed out including my walls. In this current season I have 22 attacks and 3 successful defenses. I put this out there as an example of my playing over a week at TH6. My observations are that the algorithm used to find attacking players seems flawed. Now the flaw might be intentional but it’s not immediately obvious to the player (in this case me). I know I’ve spent well over 1k in gold (single session) searching for a viable adversary. By viable I mean someone I have a chance of getting 1 or maybe 2 stars from.


The flaw I’m speaking of is, I’ve been attacked by players that have no problems completely destroying the town. These same players have towns that are so powerful I have no hope of a successful attack unless they leave their Town Halls unprotected. In contrast during my searches I have to skip a lot of suggestions because I have little to no chance of victory. I would like at least a 50/50 chance.

From my limited observations it seems as if the attack matching algorithm functions mainly on a player’s level. There is probably a modifier of + or - X levels in the algorithm thinking that it is enough to make correct matches.


The problem might be with the window of the levels with finding matches. The algorithm should take into account an attacker’s abilities as well. Additional factors should include a tactical number based on available offensive forces vs defensive forces. A numbering system can be used to simplify the algo, as an example each level 4 Army Camp can be given a value of 4 while a Barbarian King can be given a value of 7. A similar rating can be used for defensive forces such as the level of a town’s walls with the number of level 7 cannon available. Therefore players with an Offensive rating of 15 can be matched with a player with an Defensive rating of 13 - 17. This would still give some variable based on tactics.

The algorithm only looks at trophies.

First off i spend 50k looking for a raid each time.

Second you get matched with people who have the same amount of trophies as you give or take 100.

Well then the trophy thing is even worse than I thought. There's no real balance to that at all. Spending 50K to find a viable raid target isn't a wise thing either. Not saying you are wrong but the mechanics of the game needs to be balanced.

I'm sitting at 1369 trophies right now with a very new TH7. It's not sporting for a person with a TH8 or TH9 to attack someone like me due to trophies.

The only reason I can see doing that is to limit the amount of coins available in the game.

What trophy range are you in?

I'm in the Gold 3 league with 1369 trophies. The problem is if the game really is using trophies as the matching factor it's very flawed.

It is not flawed. The players you attack and the ones that attack you are based upon trophies. You said town halls 8 and 9 are attacking you. When players that have a higher level th than you attack you then they get a decreased amount of loot than they would if they attacked a th the same level as them. However I am not sure if your complaining about the loot being stolen or the trophies.

Yes there is a minor loot penalty. I don't see a trophy penalty because a player with a TH7 and level 49 with 1420 trophies attacked me. Of course he wiped me out because he had a king, 4 full army camps but he got 29 trophies. I don't remember my total coin and elixir but it's minor. I'm not even complaining about the loot nor trophies. I can get it back in very little time. So that isn't really the issue, try to look beyond the reward system. The point is how and where does a level of balance come in to play? How is a high end TH6 going to defend against even a mid-level TH7.

That's the real issue isn't it? It's a question of balance between attacker and defender. The defender can not choose the opponent so we rely on the matching algo to make sure it's a fair fight. If Dahimi's assertion that the only factor is trophies (I don't see enough evidence of that yet) then yes the algo is flawed. It's not meant to make a balanced fight where tactics and strategy should play a key role in deciding a battle. Unless the point is to have a bunch of bottom feeders who zerg an opponent but I would like to see some thought given to defense designs and attack tactics.

I'm sorry i don't understand your point. I don't think it should be this complicated. If someone is having problems with too much loot being stolen they would drop trophies. The town hall level doesn't effect amount of trophies won in a battle, however it does effect the amount of available loot. It is actually a pretty big deduction. For example, someone with th9 attacks a th7. The amount of loot available for him is reduced to 25%.

Examples:
th10 attacking th7: reduced TO 25%
th10 attacking th8: reduced TO 50%
th10 attacking th9: reduced TO 90%
th10 attacking th10: not reduced (100%)

th7 attacking th6: reduced TO 90%
th7 attacking th7: not reduced (100%)
th7 attacking th8: (100%)
th7 attacking th9: (100%)

When attacking a th that is a higher lvl then yours the loot received is 100%
I tried to stress the point that when I say reduced TO, I mean the total amount the attacker receives is 25% of the total amount that would be received if the attacker had the same level th as the defender.
Hope this helps. I tried to explain it as best as possible.
