He surrendered to the Miner with 2 stacks and had hidden fighters under the castle.
Immediately, I took the Dungeon with Tazy, level 5, with the Expert logo!
The second day, I consistently played as a single player and started clearing out the hives.
In the end, I had 6 reds, 3 angels, and 27 imps, and I reached level 124 - the map is very large.
On level 125, the opponent encountered me in the center and wrote "gg" - he only had 5 bears and 8 imps.
