1 Orc (not a Goblin!!!), 1 Ogre, 169 Goblins, 23 Ogres, 1 Ogre. Then, the third and fourth stacks in the first round will attack the Orcs. When placing 23 Orcs in the first stack, it's not certain that the Goblins in the second round will attack. When placing them in the third or fourth stack, you need to calculate. With a powerful stack of 169 Goblins, you don't need to worry about the retaliation. Theoretically, you can also try to influence morale and luck...
Regarding reloads and generation (in a very simplified form).
Reloading is actively used to "dig up" the desired hero.
Generation is used to force the computer to play the way we need it to.
And finally, experimenting with the arrangement in battle to achieve optimal morale/luck.
It's clear that if you play Hotspot without "digging up" the desired hero, you won't be able to complete it in 8 days.
