That is a tricky map, here is how I beat it

The main idea is to add your army first, then build a city in a safe place and dance around the big stacks of the enemy. Eventually, you'll gain territories, build up your army from your cities and defeat your opponent.

Round 1: Build a city
r2: move 1 up.
r3: Prepare for Defence. add +1 to 1 and move down 1. This a very important moment. The enemy from W will attack with 2 your up position and then when you transfer down, will attack your down position. You'll be able to defend both of them with success.
r4: add +2 and attack W who by now have only 1.

From this point forward, enjoy the map.

or follow what I did....

r5: +2 or W, go up 1 to V go down 1 to X, go left 1 to Q, build a city on W.
r6: Deploy 1 to 2, 1 to 1, 1 to X, Build city on X, Capture L from Q, Capture Z from 1, Capture 3 from 2, Capture Y from X, Capture S from X....
The L will drive the one stack away to left and the right side will defend the other stock while on the south you'll gain more territories.

Enjoy

You got the point......

Maybe provide a link to the level so we know which one you are talking about.

... but can you beat it in 10 turns? ;)

Haven't tried, can you beat it in 9 turns now?

11 turns is already really good. 10 I think is the limit? I would be very impressed with anyone who did it in 9 turns - but if you do somehow do it then please take a video of your turns so I can see how you did it!

It is a really nice level. Annoying at first but good puzzle.
